1. ExchangeRate-API

Development Tools, Payments, Trading & Currency Exchange

ExchangeRate-API is one of the most developer-friendly and widely-used currency exchange rate APIs available globally. Founded to provide reliable, accurate, and affordable foreign exchange data, the platform delivers real-time and historical exchange rates for 165 currencies across 200 countries — including the Nigerian Naira (NGN) — through a clean, well-documented RESTful API. It is particularly popular among Nigerian developers building fintech apps, e-commerce platforms, and financial tools that require accurate NGN conversion rates against major world currencies. **What ExchangeRate-API Does** The API provides two primary services: real-time exchange rates and historical rate data. The standard endpoint returns the latest exchange rates for all 165 supported currencies relative to a chosen base currency. The pair conversion endpoint returns the conversion rate between any two specific currencies. The enriched data endpoint includes additional localization information such as currency symbols, decimal separators, and locale-specific formatting — useful for building polished financial UIs. **Nigeria Support** NGN (Nigerian Naira) is fully supported as both a base and target currency. Nigerian developers can fetch the current USD/NGN, EUR/NGN, GBP/NGN rates in a single API call, or query any cross rate between NGN and any of the other 164 supported currencies. This makes ExchangeRate-API suitable for any Nigerian application that displays, converts, or tracks exchange rates. **Historical Data** ExchangeRate-API provides access to historical exchange rate data going back to 1990 — available on all plans including the free tier. This is a rare feature among free exchange rate APIs and makes the platform valuable for building Naira devaluation charts, historical FX analysis tools, and financial reports requiring period-specific exchange rates. **Authentication** The API uses API key authentication. Keys are issued immediately upon free sign-up with just an email address — no credit card required. The key is appended to every request URL as a query parameter. For developers who want to test without even signing up, ExchangeRate-API also offers a no-key open access endpoint that returns exchange rates without authentication, though at a lower rate limit. **Pricing Plans** ExchangeRate-API offers three tiers: - **Free**: $0/month — 1,500 requests/month, daily rate updates, no credit card required - **Pro**: $10/month ($100/year) — 30,000 requests/month, hourly rate updates - **Business**: $30/month ($300/year) — 125,000 requests/month, rate updates every 5 minutes, priority support All plans include historical data, enriched data, high availability, and a long-term support (LTS) commitment — meaning the API will not break without advance notice of deprecation. **Rate Limits** Rate limits are enforced on a monthly basis. The quota consumed is tracked and the remaining allowance is provided in response headers. When the monthly quota is exhausted, the API returns HTTP 429 (Too Many Requests). After 20 minutes without requests, rate-limited open-access (no-key) IPs are automatically unblocked. **No Sandbox (Test with Free Tier)** ExchangeRate-API does not provide a dedicated sandbox environment. Testing is done using the free tier itself — since the free tier requires no credit card and provides 1,500 real API calls per month, this is typically sufficient for development and integration testing. **Use Cases for Nigerian Developers** ExchangeRate-API is appropriate for any Nigerian project that needs exchange rate data as a data source rather than as a core payment processing feature. It does not process transactions — it only provides rate data. Common Nigerian use cases include: displaying live NGN rates on remittance platforms, powering multi-currency invoice tools, building Naira rate trackers, and auto-converting product prices in NGN to USD/EUR for international storefronts. **Important Limitation for Nigeria** ExchangeRate-API provides mid-market exchange rates sourced from financial data providers. These rates are the "official" interbank rates, not the parallel market (black market) NGN rate that often differs significantly in Nigeria. For apps that need to track or display the Nigerian parallel market rate, Monierate is a more appropriate data source. ExchangeRate-API's NGN rates reflect the official CBN/interbank rate. **Challenges** The free tier's daily update frequency means the rate data can be up to 24 hours stale — not suitable for high-frequency trading or real-time FX conversion in production payment flows. For production fintech use where real-time accuracy matters, the Pro plan ($10/month) with hourly updates is the minimum recommended tier. **Frequently Asked Questions** Q: Do I need a credit card to start? A: No. The free plan requires only an email address. Q: Does ExchangeRate-API support NGN? A: Yes. NGN is one of 165 supported currencies. Q: How current are the rates on the free plan? A: Updated once per day. For hourly updates, upgrade to Pro ($10/month). Q: Does it provide black market / parallel market NGN rates? A: No. Only official mid-market rates. Use Monierate for Nigerian parallel market rates. Q: Can I use this for live payment processing in production? A: For rate display yes, but not for actual transaction processing — this is a data API, not a payment gateway.

2. Fincra

Payments, Development Tools

Fincra is a CBN PSSP-licensed payment gateway and fintech infrastructure company enabling African businesses to collect payments locally and cross-border across 50+ currencies in 40+ countries — with a single API covering 150+ countries globally. Fincra processes millions of API requests monthly and provides checkout, virtual accounts, direct debit, and cross-border payment products to businesses ranging from startups to enterprise clients. The company maintains a dedicated developer hub at FincraHub for the Nigerian and African developer community. What the API Does The Fincra API enables developers to: process card payments (Verve, Visa, Mastercard), bank transfers, M-Pesa, mobile money, and PayAttitude; issue multi-currency virtual accounts (NGN, USD, GBP, EUR) for collections from anywhere in the world; set up direct debit mandates for recurring collections from Nigerian bank accounts; initiate cross-border payouts in 50+ currencies; and receive real-time webhook notifications for all transaction events.

Q: Does Fincra support M-Pesa? A: Yes. M-Pesa is supported as a payment method for East African collections. Q: Are sandbox and live environments the same? A: No. They are fully isolated with separate business IDs, API keys, and identifiers. You cannot transfer test data to live. Q: Does Fincra support direct debit for subscriptions? A: Yes. The Direct Debit API enables recurring collections from Nigerian bank accounts on a schedule.

3. Web3 Storage

Cloud Storage, Blockchain

Web3.Storage is a decentralized file storage API built on the InterPlanetary File System (IPFS) and Filecoin networks, providing developers with a simple HTTP API and JavaScript client for storing files in a way that is persistent, content-addressed, and decentralized. Unlike traditional cloud storage where files live on servers owned by a single provider, files stored through Web3.Storage are pinned on IPFS — a distributed peer-to-peer file system — and backed by Filecoin — a blockchain-based storage marketplace — ensuring long-term persistence without dependence on any single company or data center. The fundamental difference between Web3.Storage and traditional cloud storage is how files are addressed and retrieved. In traditional storage, files are accessed by location — a URL pointing to a specific server and path. In IPFS and through Web3.Storage, files are addressed by their content hash — a cryptographic fingerprint of the file's content called a Content Identifier (CID). Two identical files always have the same CID regardless of where they are stored, and a CID never changes as long as the file content is unchanged. This content-addressing property makes stored files verifiable: anyone can check that the file they downloaded matches the CID they were given. Uploading to Web3.Storage is accomplished through an HTTP API or the official JavaScript/TypeScript client library. A single upload call can include individual files or entire directories, and Web3.Storage returns a CID for the entire upload. The CID can then be used to retrieve the content through any IPFS gateway — either the public IPFS network, Web3.Storage's own gateway, or private gateway infrastructure. This gateway-based retrieval allows Web3.Storage content to be served to standard web browsers and applications without requiring IPFS client support. NFT (non-fungible token) metadata and assets are one of the primary use cases for Web3.Storage. When an NFT is minted on a blockchain like Ethereum or Solana, the token typically references a metadata JSON file containing the token name, description, image, and attributes. That metadata file itself references the actual NFT image or media asset. If these files are stored on a centralized server, the NFT's metadata and image can disappear if the server goes offline. Storing NFT metadata and assets on IPFS via Web3.Storage and referencing them by CID in the smart contract ensures the assets remain accessible as long as the CID is pinned, independent of any company continuing to operate. For Nigerian Web3 developers building NFT marketplaces, DeFi applications, DAOs, and blockchain games, Web3.Storage provides the storage layer that connects the decentralized application logic on-chain with the actual media and data assets off-chain. Nigerian crypto projects launching collections on Ethereum, Polygon, or Solana can use Web3.Storage to host their token metadata and artwork in a manner consistent with best practices in the NFT ecosystem. Decentralized application (dApp) front-ends can also benefit from hosting their static assets — HTML, JavaScript, CSS, images — on IPFS via Web3.Storage. When the frontend bundle is content-addressed and pinned on IPFS, the application becomes more resilient: even if the original developer's hosting goes offline, anyone holding the CID can serve the same frontend from an IPFS gateway. The Filecoin backing of Web3.Storage means uploaded content is not just pinned on IPFS but also stored in deals on the Filecoin network, a blockchain that incentivizes storage providers to reliably maintain stored data over time. Filecoin storage proofs provide cryptographic verification that stored data is actually being maintained, adding a layer of durability assurance beyond typical cloud provider SLA commitments. Web3.Storage's free tier provides substantial storage for small projects and open source work, making it accessible to Nigerian blockchain developers exploring decentralized storage without immediate budget commitment. The JavaScript client library is the primary integration path, with upload utilities that handle chunking, multipart uploads, and CID generation automatically.

4. CoinGecko API

Blockchain, Development Tools, Trading & Currency Exchange

CoinGecko is the world's largest independent cryptocurrency data aggregator, providing comprehensive market data for over 10,000 cryptocurrencies, 600+ exchanges, and 1,000+ NFT collections through a well-documented REST API. Founded in 2014 and trusted by millions of users and thousands of applications globally, CoinGecko aggregates price data from centralized and decentralized exchanges to provide reliable, manipulation-resistant market data for the entire crypto ecosystem. For Nigerian developers and businesses building crypto-related applications, CoinGecko is the most accessible and comprehensive source of crypto market data with a genuinely useful free tier. Nigeria has one of the highest per-capita cryptocurrency adoption rates in the world, driven by use cases including cross-border remittances, inflation hedging, e-commerce payments, and speculative trading. Nigerian crypto users trade a wide variety of assets — Bitcoin, Ethereum, BNB, USDT, USDC, and hundreds of altcoins — creating demand for portfolio trackers, price displays, trading tools, and crypto news aggregators that need reliable price data. CoinGecko covers all assets that Nigerian users are likely to hold or trade, including stablecoins critical for Nigerian users managing foreign exchange risk. The /simple/price endpoint is the most commonly used API for Nigerian applications — it returns current prices for specified coins in specified currencies including NGN (Nigerian Naira). Displaying portfolio values in naira is important for Nigerian users who think about their crypto holdings in the context of their domestic purchasing power. With NGN price conversion, a Nigerian portfolio tracker can show "Your Bitcoin is worth ₦28,400,000" rather than requiring users to mentally convert from USD. Historical price data via the /coins/{id}/market_chart endpoint provides time-series price, market cap, and volume data for any coin over any time period. This is the foundation for rendering price charts — giving Nigerian crypto apps the data needed for day charts, week charts, month charts, and custom timeframe views. OHLCV (open, high, low, close, volume) data is available for candlestick chart rendering. Market data endpoints return global market overview — total market cap, Bitcoin dominance, DeFi market cap, and trending metrics. Exchange data shows 24-hour trading volumes for hundreds of exchanges, including data for exchanges popular with Nigerian traders. Trending coins endpoint returns the top 7 most searched coins on CoinGecko over the past 24 hours — a useful signal for Nigerian crypto community features showing what the market is focused on. NFT floor price data from CoinGecko covers major NFT collections, providing floor prices in ETH and USD. Nigerian NFT collectors and marketplace operators can use this data to display current floor prices for popular collections without needing separate NFT-specific data providers for pricing. The free Demo API key provides 30 requests per minute and 10,000 requests per month — sufficient for small-to-medium Nigerian applications. The key is obtained after account registration on coingecko.com. For applications requiring higher throughput, Pro plans start at $129/month with 500 requests per minute and priority support. Pro API also unlocks additional endpoints including historical OHLCV with more granularity, on-chain DEX data, and advanced exchange analytics. CoinGecko's data quality is generally considered reliable and manipulation-resistant because it aggregates from many sources and applies algorithms to detect and exclude wash trading. For Nigerian developers needing trustworthy price data for portfolio displays, educational platforms, and analytics tools (rather than trading execution), CoinGecko's methodology is appropriate. For trading applications requiring institutional-grade data with SLA commitments, professional data providers with formal agreements may be more suitable.

6. Busha

Blockchain, Trading & Currency Exchange

Busha is Nigeria's first SEC-licensed digital asset platform offering crypto infrastructure for businesses and developers across Africa. The company operates two distinct API products: the Commerce API for accepting crypto payments, and the Business API for building comprehensive crypto wallets, on/off-ramps, and treasury management tools. Busha supports seven African currency corridors including NGN (Nigeria), KES (Kenya), GHS (Ghana), UGX (Uganda), TZS (Tanzania), XOF (West Africa CFA franc), and RWF (Rwanda) — making it one of the broadest multi-corridor crypto APIs on the continent. What the API Does The Busha Commerce API enables businesses to accept crypto payments from customers and settle proceeds to their accounts. It supports crypto deposits, currency conversion, and payouts via a RESTful interface. The Business API goes further — supporting full wallet management, on-ramp (fiat to crypto), off-ramp (crypto to fiat), and multi-currency treasury operations. Busha also offers stablecoin holdings as an inflation hedge tool and corporate card issuance for expense management. How Developers Use It Developers access the Commerce API documentation at developers.commerce.busha.co and the Business API at docs.busha.io. Authentication is via API keys — specifically the X-BC-API-KEY header for Commerce API requests. Keys are obtained from the Settings > API Keys section of the Busha dashboard. The API follows REST conventions with JSON payloads over HTTPS. A sandbox environment is available for testing before going live. Pricing Fiat transactions in Nigeria: NGN 150 flat deposit fee; NGN 107.50 withdrawal fee (inclusive of 7.5% VAT). Crypto withdrawal fees vary by network (e.g., 0.00005 BTC for Bitcoin withdrawals). No public monthly API subscription fee — enterprise Business API access requires contacting Busha directly. Authentication Commerce API uses the X-BC-API-KEY header. Keys can be either a secret key or a public key depending on the operation. Secret keys are used for server-side operations; public keys for client-side. Compliance Busha holds a license from the Nigerian Securities and Exchange Commission (SEC), making it the first digital asset operator licensed by the SEC in Nigeria. This is a major compliance advantage for businesses that need to work with a regulated crypto platform. The company complies with Nigerian AML/KYC requirements and requires KYC verification for all business partners. Challenges and Gotchas (1) Commerce API and Business API are separate products with separate documentation — do not confuse them. (2) Rate limits are not publicly documented — high-volume integrations should confirm limits with Busha directly. (3) Fiat settlement is to NGN bank accounts only for Nigeria — no direct USD wire. (4) Enterprise Business API access may require more extensive onboarding than Commerce API. (5) Crypto volatility between deposit and conversion can affect settlement amounts if using non-stablecoins. Company Background Busha was founded in Nigeria and is headquartered in Lagos. The company began as a consumer crypto exchange and expanded into B2B crypto infrastructure, becoming the first platform to obtain an SEC digital asset operating licence in Nigeria. Busha targets both consumer users and business clients, with a growing enterprise segment offering treasury and payment APIs. FAQs Q: Is Busha regulated in Nigeria? A: Yes. Busha is Nigeria's first SEC-licensed digital asset platform, providing strong regulatory assurance for business partners. Q: What is the difference between Commerce API and Business API? A: Commerce API is for accepting crypto payments from customers. Business API provides full wallet, on/off-ramp, and treasury infrastructure for building your own crypto-enabled products. Q: Is there a sandbox for testing? A: Yes. Busha provides a sandbox environment for development and testing before production. Q: Can I use Busha to pay suppliers in Kenya from Nigeria? A: Yes. Busha supports cross-corridor settlements between NGN, KES, GHS, and other African currencies via crypto-backed rails. Q: What cryptocurrencies are supported? A: Bitcoin, Ethereum, USDT, USDC, BNB, Solana, and other major assets are supported across multiple blockchain networks.

7. Glassnode

Blockchain, eCommerce

Glassnode is the premier on-chain analytics platform for cryptocurrency, providing over 900 metrics derived directly from blockchain data for Bitcoin, Ethereum, and other major assets. Unlike price data APIs that only track market prices and trading volumes, Glassnode analyzes the underlying blockchain itself — tracking how coins move between addresses, how long holders have been holding, how much is flowing into and out of exchanges, and how miners are behaving. This on-chain intelligence is the foundation of serious crypto market analysis and is trusted by institutional investors, hedge funds, research firms, and sophisticated retail traders globally. For Nigerian crypto investment firms, analysts, traders, and fintech companies, Glassnode provides the data layer for going beyond surface-level price charts. Nigeria's growing crypto investment community includes increasingly sophisticated participants who understand that on-chain data reveals market structure — accumulation patterns, holder conviction, exchange selling pressure, and mining economics — that price charts alone cannot show. Glassnode's API makes this institutional-quality data programmatically accessible. HODL Waves are one of Glassnode's signature metrics — a visualization showing what percentage of Bitcoin's supply was last moved in specific time bands (1 day ago, 1 week ago, 1 month ago, 1 year ago, etc.). When the "old coin" bands expand, it indicates long-term holders are accumulating and not selling. When young coin bands expand, it indicates recent buyers are active — often correlated with bull market tops. Nigerian analysts publishing market research can use Glassnode's HODL Wave data to characterize market cycles with on-chain evidence. SOPR (Spent Output Profit Ratio) measures whether coins being spent on any given day are in profit or loss relative to when they were acquired. SOPR above 1 means coins are being sold for profit (potential selling pressure); SOPR below 1 means coins are being sold at a loss (potential capitulation). The adjusted SOPR filters out short-term noise. Nigerian traders tracking Bitcoin's macro position in its market cycle use SOPR as a key sentiment and positioning indicator. Realized Capitalization calculates Bitcoin's market cap using the price at which each coin last moved, rather than the current market price. This reveals the total cost basis of all Bitcoin holders. Realized Cap-derived metrics — MVRV (Market Value to Realized Value), NUPL (Net Unrealized Profit/Loss), and Realized Price — are fundamental inputs for cycle analysis and identifying historical price floors and tops. Exchange Flow metrics track the net movement of Bitcoin and Ethereum into and out of known exchange deposit addresses. Large inflows suggest traders are moving coins to exchanges to sell; large outflows suggest accumulation. For Nigerian market intelligence platforms, exchange flow data is a leading indicator worth monitoring daily. The Derivatives module covers perpetual futures funding rates, open interest, options data, and liquidation levels — essential for Nigerian traders and analysts who monitor derivative market positioning as a sentiment indicator. The DeFi module covers Ethereum DeFi metrics: TVL by protocol, stablecoin supply, lending rates, and DEX volumes. The free tier provides access to a subset of metrics at daily resolution — sufficient for basic analysis and prototyping. Paid plans (Starter at $29/month, Advanced at $99/month, Professional at $799/month) unlock hourly and 10-minute resolution data, more metrics, and API rate limits suitable for production applications. All Glassnode data is available via a REST API with JSON responses, making it straightforward to integrate into any Nigerian analytics application or research workflow.

8. Breet API

Development Tools, Blockchain

Breet is a Nigerian crypto and stablecoin infrastructure company that enables businesses to accept cryptocurrency payments and automatically settle the proceeds in local fiat currency. The platform serves 400,000+ verified users and has executed over 500 million trades. Breet is regulated under the Nigeria Data Protection Act 2023 and certified by the Nigeria Data Protection Commission (NDPC) — making it one of Nigeria's most compliance-ready crypto payment providers. What the API Does The Breet API enables developers to: generate unique crypto deposit addresses per customer or transaction; accept payments in 13+ cryptocurrencies including Bitcoin, Ethereum, USDT, USDC, Solana, Tron, BNB, Avalanche, XRP, TON, Litecoin, Bitcoin Cash, and Dogecoin; auto-convert received crypto to Nigerian Naira (NGN) or Ghanaian Cedi (GHS); settle converted fiat directly to a business bank account; and receive real-time webhook notifications for all transaction events. The entire flow — from crypto deposit to NGN bank settlement — can happen without manual intervention. How Developers Use It Developers sign up at breet.io, complete KYB verification (typically within 24 hours), and receive an App ID and App Secret for authentication. The API is REST-based with JSON responses. A live sandbox environment is available for testing the full integration before going live. The typical integration flow: generate a deposit address for a user or invoice, monitor webhooks for deposit events, and configure auto-settlement rules to push NGN to your bank account. Most integrations go live within days with dedicated integration support from Breet. Pricing Breet charges as low as 0.5% per transaction with no setup fees, no monthly subscription fees, and no hidden FX spreads. Developers can optionally add a 0 to 10% markup on top of the Breet base fee — creating an additional revenue stream from crypto payment processing. Volume-based rates are available for high-throughput businesses on request. Authentication All API calls require an App ID and App Secret issued from the Breet merchant dashboard. These credentials are passed with each request for authentication. Settlement and Geographic Support Breet supports NGN (Nigerian Naira) and GHS (Ghanaian Cedi) as settlement currencies. Crypto deposits can be received from anywhere on-chain globally. Bank settlements are currently limited to Nigerian and Ghanaian accounts. Compliance Breet operates under the Nigeria Data Protection Act 2023 and holds NDPC certification. Business customers must complete KYB before accessing the live API. Breet is a fintech company and not a licensed bank — crypto assets are noted as volatile and Breet does not provide investment advice. Challenges and Gotchas (1) KYB is required before going live — businesses must prepare CAC documents and director IDs. (2) No card payment or USSD support — Breet is crypto-in, fiat-out only. (3) Rate limits are not publicly documented — ask Breet for limits before high-volume integrations. (4) Settlement is to NGN bank accounts only — no USD or international wire settlement currently. (5) Crypto volatility risk exists between deposit and settlement unless using stablecoins (USDT/USDC). Company Background Breet was founded in Nigeria and is headquartered in Lagos. The company started as a consumer crypto trading platform and expanded into B2B crypto payment infrastructure. It is backed by Nigerian and African venture capital and focuses exclusively on the African market, with Nigeria and Ghana as primary supported countries. FAQs Q: Can I accept USDT and settle in NGN automatically? A: Yes. Breet auto-converts USDT (and any supported crypto) to NGN and pushes settlement to your Nigerian bank account. Q: Do I need a crypto licence to use Breet API? A: No. Breet holds the necessary regulatory certifications. You only need to complete KYB as a business customer. Q: Is there a sandbox for testing? A: Yes. Breet offers a live sandbox environment for full integration testing before production. Q: What is the settlement time? A: Typically within minutes for stablecoins. Volatile assets like BTC may have slight delays depending on network confirmations. Q: Can I add my own fee on top of Breet pricing? A: Yes. Breet allows you to apply a 0 to 10% markup on top of their 0.5% base fee, creating a revenue stream from your integration.

9. Moralis

Blockchain

Moralis is a Web3 data API platform that provides pre-indexed blockchain data through simple REST API calls, eliminating the need for developers to build and maintain custom blockchain data indexing infrastructure. Instead of running a full node and writing custom scripts to parse and store blockchain events, Nigerian Web3 developers can call Moralis endpoints to retrieve pre-processed, structured data — wallet token balances, NFT portfolios, transaction histories, DeFi positions, and token prices — across multiple blockchains with millisecond response times. The fundamental challenge that Moralis solves is blockchain data access. Raw blockchain nodes provide event logs and state data in a low-level format that requires significant parsing and indexing work to transform into useful application data. Fetching all ERC-20 tokens held by a wallet address requires calling balanceOf on every token contract — impractical at scale. Fetching all NFTs owned by a wallet requires indexing every Transfer event across every NFT contract. Building this infrastructure from scratch takes weeks or months. Moralis has already built this indexing layer and exposes it through clean REST endpoints. Wallet API is the foundation — a single API call retrieves all native tokens (ETH, MATIC, BNB), all ERC-20 tokens with balances and USD values, and metadata for any wallet address across multiple chains simultaneously. This is the core of any portfolio tracking application. For Nigerian crypto users tracking their multi-chain holdings, Moralis provides the data layer that makes this possible without custom indexing. NFT API retrieves all NFTs owned by a wallet address, with metadata (name, description, image URL, attributes), collection information, current floor price, and transfer history. Building a Nigerian NFT gallery or NFT-gated application requires knowing which NFTs a user holds — Moralis provides this in one API call that would otherwise require custom event log indexing across thousands of NFT contract addresses. Transaction History API provides complete transaction history for any wallet — native transfers, ERC-20 token transfers, NFT transfers, internal transactions, and decoded smart contract interactions. For Nigerian blockchain applications showing users their transaction history, this eliminates the need to build custom transaction indexing and provides clean, decoded data rather than raw event logs. DeFi Positions API shows a wallet's current positions across major DeFi protocols — Uniswap, Aave, Compound, Curve, and others — including supplied assets, borrowed amounts, liquidity pool shares, and yield farming positions. For Nigerian DeFi users managing complex positions across protocols, a unified dashboard showing all DeFi exposure in one view requires exactly this cross-protocol position aggregation. Token Price API provides real-time and historical token prices sourced from on-chain liquidity (DEX pricing) for any ERC-20 token, including long-tail tokens not listed on major price aggregators. This is valuable for Nigerian DeFi applications displaying portfolio values and PnL calculations. Moralis Streams API provides real-time webhook notifications for blockchain events — address activity, token transfers, NFT mints, smart contract events — across all supported chains. Nigerian applications that need to react in real-time to on-chain events (payment receipt confirmation, NFT transfer, DeFi event) use Streams instead of polling. Chain support covers Ethereum, Polygon, BNB Smart Chain, Avalanche, Fantom, Cronos, Arbitrum, Optimism, and Solana. The breadth of coverage reflects the multi-chain reality of the current NFT and DeFi ecosystems where Nigerian users operate. The free tier (40,000 API calls per month) is sufficient for small production applications. For Nigerian developers building portfolio trackers, NFT marketplaces, DeFi dashboards, or any application requiring aggregated wallet data, Moralis dramatically reduces development time compared to building custom indexing from scratch.

10. Infura

Blockchain, Development Tools

Infura is a blockchain infrastructure service operated by ConsenSys, providing managed Ethereum nodes, IPFS storage, and related Web3 APIs. Founded in 2016 — making it the original managed Ethereum node provider — Infura is most famous as the infrastructure powering MetaMask, the world's most widely used Ethereum wallet. This heritage makes Infura the most battle-tested and widely trusted Ethereum node provider in the ecosystem, relied upon by millions of applications and users globally. For Nigerian blockchain developers, Infura represents the established, reliable choice for Ethereum development infrastructure. The name recognition and MetaMask relationship provide an implicit trust signal — infrastructure mature enough to power the wallet used by over 30 million users globally is reliable enough for Nigerian DApps. The free tier (100,000 requests per day, 10 requests per second) is sufficient for development and moderate production use. Ethereum support is comprehensive — mainnet, all active testnets (Sepolia, Goerli), and the Ethereum Holesky testnet are available. Archive node access allows querying historical Ethereum state at any past block — essential for analytics applications that need to reconstruct historical account balances, contract states, or price data at specific points in time. Archive queries incur additional costs but are invaluable for research and analytics use cases. IPFS (InterPlanetary File System) integration is a significant Infura differentiator. IPFS is the decentralized storage network used to store NFT metadata and media files in a content-addressed manner — files stored on IPFS are identified by their content hash, making them immutable and verifiable. Infura provides an IPFS gateway and pinning service, allowing developers to upload files to IPFS through Infura's infrastructure and have them pinned (kept available persistently). Nigerian NFT projects and Web3 applications needing decentralized file storage use Infura IPFS as part of their storage architecture. Polygon RPC support extends Infura beyond Ethereum to the most widely used Layer 2 / sidechain for Nigerian-accessible DeFi, given Polygon's significantly lower transaction fees. Filecoin (decentralized storage protocol) is also supported for teams integrating with Filecoin-based storage solutions. Gas API provides real-time gas fee recommendations for Ethereum and Polygon, giving applications current fast/standard/safe-low gas price suggestions. This is essential for transaction-sending applications that need to set appropriate fees without overpaying. Transaction API provides specialized endpoints for transaction management — submission, status tracking, and receipt retrieval — with standardized error handling. This simplifies the transaction lifecycle management that is critical for Nigerian fintech and payment applications using blockchain transactions. WebSocket subscriptions allow real-time event streaming — new blocks, pending transactions, contract event logs, and other Ethereum event types — via persistent WebSocket connections. Applications displaying live blockchain data to Nigerian users use WebSocket subscriptions for event-driven updates. The Project ID authentication model is straightforward: each Infura project receives a Project ID that is embedded in the HTTPS and WebSocket endpoint URLs. The Project Secret provides additional security for server-side calls. API key rotation and project management are handled through the Infura dashboard. Infura is the most conservative choice for Nigerian Ethereum developers — maximally trusted, most documentation, most tutorials referencing it, and MetaMask compatibility guaranteed. Teams that prioritize stability and ecosystem integration over the most recent enhanced API features typically choose Infura as their primary Ethereum provider.

11. Helius

Blockchain, Development Tools

Helius is the leading developer platform for Solana, providing enhanced RPC node access, purpose-built Solana APIs, webhooks for real-time event monitoring, and developer tooling specifically designed for the Solana blockchain ecosystem. Founded in 2022 and rapidly adopted by many of the top Solana protocols and applications, Helius fills the same role in the Solana ecosystem that Alchemy or Moralis fills in the Ethereum ecosystem — transforming raw RPC access into developer-friendly, high-level APIs that reduce the complexity of building on Solana. Solana is one of the fastest and cheapest smart contract blockchains, with transaction fees typically below $0.001 and confirmation times under 1 second. These characteristics make Solana particularly attractive for Nigerian users and developers who need high-frequency, cost-efficient transactions. DeFi applications, NFT marketplaces, payments, and gaming on Solana are accessible to Nigerian users at a fraction of the cost of Ethereum mainnet interactions. Helius provides the infrastructure foundation for building these applications. The enhanced transaction parsing API is Helius's most immediately valuable feature for application developers. Raw Solana transactions contain instruction data that is difficult to interpret without knowing the specific program being called. Helius parses these raw instructions into human-readable transaction descriptions — identifying token swaps on DEXes, NFT purchases and sales, liquidity provision events, token transfers, and other activity types with clear labels and amounts. Nigerian applications showing users their transaction history can display meaningful descriptions rather than cryptic instruction data. The DAS (Digital Asset Standard) API provides standardized access to Solana NFT and compressed NFT data. Solana's compressed NFTs (cNFTs) are a technical innovation that reduces NFT minting and storage costs by orders of magnitude, enabling mass-scale NFT use cases. DAS API provides uniform access to both regular NFTs and compressed NFTs through a consistent interface, abstracting the underlying complexity. Nigerian NFT projects building on Solana benefit from this standardized data access for portfolio displays, marketplace listings, and NFT verification features. Webhooks via Helius allow real-time monitoring of Solana addresses and program interactions. When a specified wallet receives tokens, an NFT transfer occurs, or a smart contract event matches defined criteria, Helius delivers a webhook event to the application. This eliminates the need for Nigerian applications to poll the blockchain continuously, reducing both latency and API usage costs. The Priority Fee API provides real-time recommendations for Solana transaction priority fees — the additional micro-lamport payments that help transactions land faster during network congestion. For Nigerian applications where transaction confirmation speed matters to user experience, this API ensures fees are set appropriately without overpaying during normal conditions. Archive node access through Helius allows querying historical Solana state and transaction data at any past slot number — important for analytics applications, historical price data, and audit tools that need to reference the blockchain's past state. Standard Solana RPC nodes only retain recent state; archive queries require specialized infrastructure. The free tier (1 million credits per month) covers development and low-to-medium traffic production. Credits are consumed at different rates by different API endpoints — basic RPC calls consume fewer credits than enhanced parsing calls. Paid plans from $49/month scale to the throughput needs of larger applications. For Nigerian developers entering the Solana ecosystem, Helius is the recommended starting point — superior to Ankr or QuickNode for Solana-specific development due to the purpose-built enhanced APIs, active development by a Solana-native team, and deep integration with the Solana developer community.

12. Pyth Network

Development Tools, Blockchain

Pyth Network is a first-party oracle network that aggregates and publishes real-time price data directly from institutional market participants — trading firms, market makers, and exchanges like Jump Trading, Jane Street, Virtu Financial, Binance, OKX, and CBOE. Unlike oracle networks that aggregate prices from DEXes or centralized API providers, Pyth's data comes from the firms that actually make markets and set prices in traditional and crypto markets. This first-party model means Pyth prices are more accurate, more responsive, and more manipulation-resistant than data derived from secondary sources. For Nigerian DeFi developers building on Solana, Ethereum, or any of Pyth's 50+ supported chains, Pyth is the most credible source for high-frequency price data. Nigeria's growing DeFi developer community is increasingly building on Solana — attracted by its high throughput and low fees — as well as on EVM chains. Pyth is the dominant oracle solution on Solana, used by the majority of Solana DeFi protocols. Any Nigerian developer building lending protocols, perpetual futures, options, or structured products on Solana will encounter Pyth as the standard price oracle. On EVM chains, Pyth competes with Chainlink as a high-performance alternative, particularly for applications requiring sub-second price updates. The pull oracle model is Pyth's key architectural innovation. Rather than pushing price updates on-chain continuously (which costs gas on every update), Pyth keeps the latest prices available off-chain in its Hermes service. When a smart contract needs a price, it fetches a signed price update from Hermes and passes it to the smart contract in the same transaction — the contract verifies the signature on-chain and uses the fresh price. This means prices are only written to the blockchain when actually needed, significantly reducing oracle infrastructure costs. For Nigerian DeFi protocols with many users, this translates to lower per-transaction costs. Each Pyth price update includes not just the price but also a confidence interval — the range within which the true price lies with high probability. A BTC/USD update might report a price of $65,000 with a confidence interval of $50, meaning the true price is between $64,950 and $65,050. This confidence interval is a critical signal: when market conditions are volatile and the confidence interval widens significantly, a DeFi protocol can increase collateral requirements or pause liquidations to avoid acting on imprecise prices during market stress. Pyth covers over 500 price feeds including cryptocurrencies, US equities (Apple, Microsoft, Tesla, S&P 500 ETF), forex pairs (EUR/USD, GBP/USD, and increasingly USD/NGN), and commodities (gold, silver, crude oil). For Nigerian developers building products that bridge traditional finance and DeFi — tokenized stocks, FX-backed stablecoins, commodity-linked tokens — Pyth is the only oracle that covers all these asset classes under one integration. The Hermes REST API (hermes.pyth.network) allows off-chain applications to fetch the latest prices and historical price data without any authentication or API key. This is useful for Nigerian applications that need current prices for display purposes — portfolio dashboards, price tickers, and market data widgets — without on-chain interaction. WebSocket streaming provides real-time price updates for applications that need continuous price feeds in their frontend. Pyth is entirely free to use — there are no subscription fees, no API keys to manage, and no per-query costs. The price data is subsidized by the first-party data providers who benefit from the adoption of protocols using Pyth data. For Nigerian developers and startups, this zero-cost access to institutional-grade price data is an extraordinary advantage.

13. RedStone

Blockchain

RedStone is a modular oracle network designed to overcome the limitations of traditional push-based oracle models like Chainlink's Data Feeds. Instead of continuously updating prices on-chain regardless of whether anyone needs them (wasting gas on every update), RedStone introduces two delivery models: RedStone Core (calldata model) and RedStone Classic (push model). This architectural flexibility, combined with coverage of over 1,000 price feeds — including assets that Chainlink and Pyth do not cover — makes RedStone the oracle of choice for DeFi protocols working with liquid staking tokens, liquid restaking tokens, real-world assets, and long-tail cryptocurrency markets. For Nigerian DeFi developers building sophisticated protocols, RedStone fills critical gaps that competing oracles leave unfilled. Chainlink and Pyth cover the most liquid, highest-volume assets (BTC, ETH, major stablecoins) but have limited coverage for the long-tail of the crypto market. RedStone's 1,000+ feeds include emerging DeFi tokens, liquid staking derivatives, and RWA tokens that are becoming central to advanced DeFi strategies. A Nigerian protocol supporting diverse collateral types needs an oracle that covers the full asset universe its users hold. The RedStone Core model works by embedding signed price data in transaction calldata rather than storing it in smart contract state. When a user calls a contract function that needs a price — for example, depositing collateral into a lending protocol — the frontend fetches a signed price package from RedStone's data availability layer and appends it to the transaction calldata. The smart contract (wrapped with RedStone's EVM connector) extracts and verifies the price from calldata before executing the main logic. The key advantage: gas is only consumed for pricing when an actual transaction occurs, not on every price update interval. For protocols with many supported assets but infrequent individual usage, this dramatically reduces oracle costs. The RedStone Classic model behaves like traditional push oracles — price updates are pushed to on-chain contracts on a schedule or when price deviation thresholds are exceeded. This is suitable for applications that need on-chain prices accessible to any contract without requiring users to attach price data to their transactions. RedStone Classic is backward-compatible with the Chainlink AggregatorV3Interface, allowing protocols to switch from Chainlink to RedStone without changing their consumer contract code. LST (Liquid Staking Token) and LRT (Liquid Restaking Token) price feeds are a RedStone specialty. Tokens like stETH, wstETH, weETH, rsETH, and ezETH are yield-bearing — their value grows over time as staking rewards accrue. Correctly pricing these tokens for DeFi collateral purposes requires tracking the current exchange rate against the underlying asset (ETH), not just the DEX spot price, which can diverge. RedStone's LST feeds specifically handle this exchange-rate-based pricing, making them more accurate than generic price feeds for yield-bearing assets. RWA (Real-World Asset) token feeds cover tokenized government bonds, money market funds, and other yield-bearing traditional finance instruments increasingly appearing in DeFi. Nigerian platforms building RWA-backed stablecoins or yield products can use RedStone's RWA feeds to maintain accurate on-chain valuations without custom oracle infrastructure. RedStone is entirely free to use for standard feeds. The @redstone-finance/evm-connector npm package and corresponding Solidity library are open source and integrate into any EVM project. Nigerian developers can start building with RedStone oracles in a few hours — the documentation includes comprehensive examples, the testnet deployments are available for integration testing, and the team is responsive to questions in their developer Discord.

14. Square API

eCommerce, Payments, Development Tools

Square API is a comprehensive payment and commerce platform API from Square, Inc. (now Block, Inc.) that enables developers to build custom point-of-sale applications, online payment flows, inventory management systems, subscription billing, and retail commerce solutions. Square provides a deeply integrated suite of commerce APIs covering payments, orders, inventory, customer management, loyalty programs, and employee management that work together to provide a complete retail and services business management platform. IMPORTANT NOTE FOR NIGERIAN DEVELOPERS: Square does not currently operate in Nigeria and does not support Nigerian merchants registering for Square accounts, processing NGN transactions, or receiving settlements to Nigerian bank accounts. Square operates in the United States, Canada, United Kingdom, Australia, Japan, France, Spain, and Ireland only. Nigerian businesses looking for equivalent payment processing capabilities should use Nigerian-licensed alternatives such as Paystack, Flutterwave, Monnify, or Kora. Despite not supporting Nigeria directly, Square API is documented here for several relevant reasons. First, Nigerian tech professionals working for international companies, remote contractors, and developers building products for non-Nigerian markets frequently work with Square. Second, Nigerian developers building applications for clients in Square-supported markets need API documentation to understand the integration requirements. Third, the architectural patterns used by Square — particularly their Payments API, Web Payments SDK, and order management system — are studied by Nigerian developers learning payment system design. The Square Payments API processes card-not-present payments through the Web Payments SDK (a JavaScript library that renders a PCI-compliant card entry form in web browsers) and the In-App Payments SDK (for iOS and Android native apps). These SDKs handle card data capture and tokenization in the browser or app, then pass a payment token to the backend which makes a charge call to the Square Payments API without sensitive card data ever touching the developer's servers. This architecture demonstrates PCI compliance best practices relevant to payment developers globally. Square Orders API provides comprehensive order lifecycle management: creating orders with line items, modifiers, and taxes, updating order status, applying discounts, processing partial fulfillments, and attaching payments to orders. This orders-centric model — where payments fulfill orders rather than existing independently — is architecturally different from many payment APIs and represents a more complete retail commerce model that connects inventory, pricing, and payment into a unified order record. Square Inventory API tracks product stock levels across multiple locations, providing real-time inventory counts, adjustment tracking, and low-stock alerting. For developers building multi-location retail management systems in Square-supported markets, the inventory API enables the stock synchronization between physical and online sales channels that prevents overselling and allows accurate availability display. Square Subscriptions API handles recurring billing, creating subscription plans with billing cadences, trial periods, and pricing tiers, and automatically charging customers on schedule. Subscription webhooks notify the integrating application of billing events, failed payments, and subscription status changes. This recurring billing infrastructure is used by subscription box services, membership businesses, and SaaS products operating in Square markets. Square Loyalty API builds customer loyalty programs directly into the payment flow, automatically awarding points on eligible purchases, tracking redemption history, and applying loyalty discounts at checkout. For businesses in Square-supported markets wanting to reward repeat customers without separate loyalty program infrastructure, the integrated loyalty system captures purchase data automatically through the normal payment flow. Nigerian developers can access Square's sandbox environment freely for learning and testing purposes, using test credentials to exercise all API endpoints without processing real payments.

15. Sequence

Blockchain, Trading & Currency Exchange

Sequence is a comprehensive Web3 infrastructure platform specifically designed for games and consumer applications, providing smart wallet technology, NFT tools, marketplace infrastructure, fiat on-ramps, and a multi-chain indexer under one unified platform. Where general-purpose Web3 tools like Thirdweb focus broadly on developer experience, Sequence goes deep on the gaming and consumer use case — with Unity and Unreal Engine SDKs, in-game marketplace contracts, and player-friendly onboarding flows that hide crypto complexity entirely from end users. For Nigerian game developers and NFT platforms, Sequence solves the most critical problem in Web3 consumer adoption: friction. The Nigerian gaming market is large and mobile-first, with millions of players who have smartphones but no crypto wallets, no understanding of gas fees, and no interest in learning blockchain concepts just to play a game. Sequence's embedded smart wallet eliminates every barrier: players sign in with email or Google, receive a wallet automatically, and play the game. The crypto infrastructure is entirely invisible until the player chooses to withdraw or trade their earned assets. The Sequence Smart Wallet is a smart contract wallet (built on ERC-4337 account abstraction) that is created for every new user automatically. Unlike externally owned accounts (EOAs) like MetaMask, smart contract wallets support gasless transactions (the game developer sponsors gas), social recovery (the user can recover their wallet via email if they lose access), and batched transactions (multiple operations in one transaction). For Nigerian game studios, sponsoring gas fees for players is a business decision similar to offering free shipping — it removes a barrier that would otherwise prevent most users from engaging. The Embedded Marketplace allows Nigerian NFT platforms and games to deploy their own branded marketplace — for buying, selling, and auctioning NFTs — without building marketplace smart contracts from scratch. The marketplace supports fixed-price listings, Dutch auctions, and offer-based trading across any NFT collection. It is deeply integrated with the Sequence wallet, so a player who earns an NFT in-game can immediately list it for sale in the game's marketplace without leaving the application. The NFT Minting API allows Nigerian developers to mint NFTs programmatically via API calls — no smart contract interaction required from the application layer. When a player achieves a milestone or makes a purchase, the game server calls the Sequence Minting API with the player's wallet address and the token metadata, and the NFT is minted on-chain. This server-side minting model is far simpler than requiring the player to initiate a blockchain transaction. The Fiat On-Ramp integration enables players to purchase cryptocurrency or in-game tokens directly with a debit/credit card through the Sequence interface. For Nigerian players who want to buy in-game items without managing a separate crypto exchange account, this is the most convenient entry point. Card payment support for Nigerian Verve and Visa cards (subject to issuer restrictions) broadens the addressable market for Nigerian Web3 games. The Multi-Chain Indexer is a high-performance API for querying token balances, NFT ownership, and transaction history across Ethereum, Polygon, BNB Chain, Arbitrum, and other chains. It indexes data much faster than querying blockchain nodes directly and provides a consistent API structure regardless of chain. Nigerian game backends can use the indexer to check a player's on-chain inventory, verify NFT ownership before granting in-game benefits, and display portfolio values. The free tier and affordable Growth plan ($149/month) make Sequence viable for Nigerian indie game studios and startups in early stages, with clear upgrade paths as player counts grow.

16. Tatum

Blockchain, Trading & Currency Exchange

Tatum is a blockchain-as-a-service platform providing a unified REST API that enables developers to interact with over 100 blockchain networks — including Bitcoin, Ethereum, BNB Chain, Tron, Solana, Polygon, Cardano, XRP, Dogecoin, and dozens more — through a single consistent API structure. Rather than learning the specific RPC interfaces, SDK libraries, and node management requirements for each blockchain, Nigerian developers using Tatum interact with every chain through the same endpoint patterns. This dramatically reduces the time required to build multi-chain cryptocurrency wallets, exchanges, and payment systems. Nigeria's position as Africa's largest crypto market means Nigerian developers frequently need to support multiple blockchains simultaneously. Nigerian users hold Bitcoin as a store of value, USDT on Tron for cheap transfers, Ethereum for DeFi access, and BNB Chain for affordable trading. A wallet application serving Nigerian users must support all of these chains. Without Tatum, building multi-chain support means separate integrations for each blockchain — different RPC formats, different transaction structures, different fee models, different SDK libraries. With Tatum, one API key and one consistent REST interface handles everything. Wallet generation through Tatum creates HD (hierarchical deterministic) wallets with master private keys and extended public keys for any supported blockchain. From a single mnemonic, developers can derive unlimited individual receiving addresses — the standard architecture for exchange and custodial wallet systems that need unique deposit addresses per user. Tatum handles the cryptographic complexity of key derivation for every chain, while the developer retains and stores the private key material securely. The Virtual Account system is Tatum's most powerful feature for exchange and wallet builders. Virtual accounts are an off-chain ledger system where user balances are tracked in Tatum's database rather than on the blockchain for every small transaction. Users can transfer balances between each other instantly and for free off-chain, while actual blockchain settlements happen in batches or when users withdraw. This is the architecture behind centralized exchanges — and Tatum makes it available to Nigerian exchange operators without building custom ledger infrastructure. Transaction broadcasting covers the full lifecycle: constructing a signed transaction (Tatum generates the raw transaction with correct nonce, gas, and fee parameters), signing it with the wallet's private key, and broadcasting it to the blockchain network. For Bitcoin, this means handling UTXO selection and change address management. For Ethereum, this means nonce management and gas estimation. Tatum abstracts all chain-specific mechanics. NFT operations include minting, transferring, burning, and querying NFTs across EVM chains and Solana. Nigerian NFT platforms can mint collections programmatically by calling Tatum's NFT API rather than deploying and managing smart contracts directly. Token operations support creating ERC-20 / BEP-20 tokens, transferring them, and checking balances — all through REST API calls. Webhook notifications alert Nigerian backend servers when specific blockchain events occur: incoming transactions to monitored addresses, transaction confirmations, NFT transfers, and smart contract events. This enables Nigerian exchanges and payment processors to detect deposits automatically without polling the blockchain. The free tier with 1 million credits per month and 5 requests per second is sufficient for Nigerian projects in early stages. Paid plans scale from $79/month to $599/month with higher throughput, and enterprise plans provide dedicated infrastructure with SLA guarantees for production Nigerian exchanges and fintech platforms.

17. Stellas Microfinance Bank API

Banking & Fintech, Development Tools, Payments

Stellas Microfinance Bank provides payment APIs and collections services focused on microfinance use cases. The Stellas MFB API enables payment processing and collection management for microfinance operations. Nigerian microfinance companies use Stellas APIs for payment processing.

18. BlockCypher

Blockchain, Development Tools

BlockCypher is a cloud-based blockchain API platform that provides REST API access to Bitcoin, Litecoin, Dogecoin, Dash, and Ethereum without requiring developers to run their own blockchain nodes. Running a full Bitcoin node requires significant hardware resources, continuous uptime, and weeks of initial blockchain synchronization. BlockCypher eliminates all of that — a Nigerian developer can query Bitcoin addresses, build and broadcast transactions, and monitor for payments within minutes of obtaining a free API token. For Nigerian fintech companies, payment processors, and wallet developers working with Bitcoin and other UTXO-based cryptocurrencies, BlockCypher is one of the most mature and reliable API options available. Nigeria is one of the top countries globally for peer-to-peer Bitcoin trading, driven by use cases including cross-border remittances (sending value internationally at low cost), savings in a stable digital asset (hedging against naira depreciation), and merchant payments. Nigerian developers building Bitcoin-related applications — wallets, payment gateways, OTC desks, remittance services — all need reliable API access to the Bitcoin network. BlockCypher's 99.99% uptime SLA and globally distributed infrastructure make it suitable for production Nigerian fintech applications. Address and transaction querying covers the fundamentals: get the balance and transaction history for any Bitcoin address, get details of any transaction by hash, and get block information by height or hash. The /addrs/{address}/balance endpoint returns confirmed and unconfirmed balances along with transaction counts — the data needed to display a wallet balance. The /txs/{hash} endpoint returns full transaction details including inputs, outputs, amounts, confirmations, and block information. BlockCypher's Confidence Factor is a unique feature for unconfirmed Bitcoin transactions. When a user sends Bitcoin but the transaction has not yet been included in a block (0 confirmations), BlockCypher analyzes the network's mempool, the transaction fee, and propagation patterns to estimate the probability that the transaction will be confirmed. A confidence of 99%+ on a zero-confirmation transaction is generally safe to act on for small amounts — useful for Nigerian merchants who want to provide faster payment confirmation experiences. Webhook notifications allow Nigerian applications to subscribe to address activity events: receive an HTTP POST notification when any transaction involving a monitored address is detected in the mempool or confirmed in a block. This is the foundation of any payment detection system — instead of polling the blockchain, the application registers a webhook and gets called when payment arrives. BlockCypher supports webhooks for new transactions, confirmations, double-spend attempts, and other events. The Transaction Builder API handles the complexity of UTXO transaction construction: selecting which unspent outputs to use as inputs, calculating change, and handling fee estimation. Nigerian developers can pass a list of sending addresses, destination addresses, and amounts, and BlockCypher returns a partially constructed transaction ready for signing. After signing with the private key locally, the transaction is submitted to BlockCypher for broadcasting. Multisig (multi-signature) transaction support allows building 2-of-3 or other threshold signature schemes — critical for Nigerian crypto custody solutions and escrow services that need multiple key holders to authorize fund movements. BlockCypher handles the technical complexity of multisig address creation and PSBT (partially signed Bitcoin transaction) workflows. The private BlockCypher Test Chain (bcy/test) is a custom test blockchain that produces blocks instantly and where test tokens can be obtained from a faucet for free. This allows Nigerian developers to test complete Bitcoin payment flows — including multiple confirmations and webhook delivery — without waiting for real Bitcoin testnet blocks. The free tier with an API token provides 200 requests per hour, sufficient for development and low-traffic production use. Paid plans scale to 30 requests per second (Micro at $20/month) and beyond for high-volume Nigerian applications.

19. CheapDataHub API

Communications, Payments

CheapDataHub is a Nigerian VTU (Virtual Top-Up) platform that offers both a consumer-facing reseller app/website and a dedicated REST API for developers (documented separately at cheapdatahub.ng/api-for-developers/). The API lets developers programmatically purchase airtime and data bundles for MTN, Glo, Airtel and 9Mobile, pay electricity bills to Nigerian Distribution Companies (Discos) in prepaid and postpaid modes, subscribe to DSTV, GOTV and Startimes cable TV packages, and buy exam PINs for WAEC, NECO, NABTEB and JAMB. Developers sign up for an account and receive API keys automatically; there is no separate developer-application process. Documented endpoints include wallet balance lookup, airtime purchase, data purchase, electricity purchase, cable TV purchase, exam-PIN products/purchase, and transaction status/history, all served from a live base URL at cheapdatahub.ng/api/v1/resellers/ and consumed as JSON over HTTPS. A public plan-IDs page lists the numeric plan_id values (e.g. network, bundle size, validity, and price) that must be passed in data and cable-TV purchase requests, and CheapDataHub states these are kept up to date as network pricing changes. The platform supports real-time webhooks for transaction status changes (initiated, processing, successful, failed, refunded) so integrators can react to delivery outcomes asynchronously instead of polling. Documented error responses cover unauthorized access, insufficient wallet balance, duplicate requests, validation errors and server errors, and code samples are provided in PHP (cURL), JavaScript (Axios) and Python (Requests) for at least the airtime endpoint. CheapDataHub markets itself as a low-cost aggregator with claims of over 20,000 active users, 99.9% uptime and sub-2-second average delivery time, alongside a mobile app on Google Play and the App Store. It positions the API as suited to developers and small businesses building their own VTU resale platforms, school portals, or fintech-adjacent apps that need to sell airtime, data, bills or exam pins without negotiating directly with telcos, Discos or DStv/GOtv/Startimes.

20. eBills API

Communications, Payments

eBills is a Nigerian digital payments platform, operated by FraNKAPPWeb Technologies and based in Awka, Nigeria, that lets businesses and developers programmatically sell VTU (Virtual Top-Up) services. The eBills API is a RESTful, JWT-authenticated API covering airtime top-ups for MTN, Glo, Airtel, and 9mobile; data bundles across all major Nigerian networks plus Smile; cable TV subscription renewals for DStv, GOtv, Startimes, and Showmax; electricity bill payments across roughly a dozen Nigerian distribution companies (including IKEDC, EKEDC, and KEDCO); recharge card (ePIN) printing for all networks; and betting wallet funding for platforms such as Bet9ja, SportyBet, and BetKing, among others. To integrate, a developer first creates a reseller account on the eBills platform and funds a wallet, then completes tiered KYC verification (email, BVN, or full identity verification) that governs daily transaction limits. API credentials are issued through a developer dashboard, and requests are authenticated using JWT bearer tokens obtained via a token endpoint, valid for seven days per token. Developers can optionally whitelist their server IPs for added security. eBills positions its API around cost savings: integrators pay zero service fees and receive discounted rates versus the standard consumer-facing prices on the site, spanning discounts on data, airtime, cable TV, electricity, ePINs, and betting funding. The platform also offers ancillary consumer services (bulk SMS, WASSCE/JAMB exam pin sales, and Chinese currency funding) that are not confirmed to be part of the developer API surface. eBills is aimed at Nigerian developers, fintech startups, and businesses that want to embed bill payment and airtime/data resale into their own apps or websites without dealing directly with telecom and utility billers, similar in category to other Nigerian VTU aggregator APIs.

21. GSubz API

Communications, Payments

GSubz is a Nigerian VTU (Virtual Top-Up) platform and API provider that lets developers integrate instant airtime recharge, mobile data bundle purchases, cable TV subscription payments (DStv, GOtv), and electricity bill payments into their own websites and applications. It supports the major Nigerian mobile networks - MTN, Glo, Airtel, and 9mobile - alongside utility billers, positioning itself as a reseller-friendly backend for VTU and bill payment businesses. The GSubz API is a straightforward REST-style HTTP API built around a small set of endpoints: `category` and `service` to discover available service types, `fields` and `plans` to retrieve required parameters and data/TV plans for a given service, `variation` to fetch pricing for a specific plan, and `pay`/`verify` to submit and confirm transactions. A `balance` endpoint lets integrators check their GSubz wallet balance programmatically. Payments are split into two models: flexible payments (like airtime, where the buyer sets the amount) and fixed payments (like data plans and TV subscriptions, where the amount is predetermined by the selected plan). Authentication is via a Bearer API key sent in the Authorization header of every request, obtained after registering a free GSubz account. Developers fund their account wallet and transactions are debited at GSubz's discounted resale rates rather than paying a separate API fee, making it economically similar to other Nigerian VTU resale platforms (e.g. VTpass, Sailmony). GSubz also operates a Chinese-goods dropshipping storefront under the same brand, but the API documentation itself is scoped strictly to VTU/bill-payment services (airtime, data, TV, electricity), which is what this listing covers. The documentation does not mention rate limits, IP whitelisting, or webhook/callback notifications for transaction status - developers should expect to poll the verify endpoint to confirm transaction outcomes. GSubz is aimed at Nigerian developers, resellers, and small businesses building VTU storefronts, WhatsApp/Telegram bots, school portals, or internal tools that need to sell airtime, data, cable TV, and electricity tokens programmatically to Nigerian end users.

22. Airtel Money API

Development Tools, Payments

Airtel Money pan-African mobile money API providing collections, remittances, payments, and disbursements across multiple African countries including Nigeria. Airtel Money enables businesses to integrate mobile money capabilities across Airtel's presence in 14+ African countries through a single unified API. Supports multi-country deployments for businesses operating across Africa with seamless cross-border mobile money transfers and localized payment experiences.

23. InstantMobileNG API

Communications, Payments

InstantMobileNG is a Nigerian Value Added Service (VAS) and VTU (Virtual Top-Up) platform that has operated since 2015, describing itself as one of the founding providers of VTU digital marketing business in Nigeria and claiming over 30,000 clients served. The company's core consumer-facing business is automated sale of airtime, mobile data bundles, cable TV subscriptions (DStv, GOtv, StarTimes), electricity bill payments, exam result-checker pins (WAEC/NECO), and instant bank transfers, alongside VTU reseller portal setup and affiliate programs. For developers, InstantMobileNG exposes an API so third-party websites and apps can plug directly into its VTU services rather than reselling through its portal manually. The documented API (hosted under a platform called MODATA, base path modata.com.ng/api/) uses bearer-token authentication and simple GET/POST endpoints, including POST /data/ for buying data bundles (network, mobile number, plan ID, ported-number flag) and POST /topup/ for airtime top-ups (network, amount, mobile number, VTU or Share-and-Sell type). Cable TV, electricity, and education (exam pin) services are also listed as integrable, though their endpoint-level documentation is thinner than the data and airtime endpoints. Access is gated behind payment: developers pick one of three one-time developer packages (₦10,000, ₦15,000, or ₦35,000), pay by bank transfer, then email their name, contact details, developer website address, and payment date to support for manual verification. Approval is stated to take 1-48 hours on business days, after which an API key/token and admin dashboard access are issued for monitoring transactions. There is no free trial or free API tier described anywhere on the site. InstantMobileNG is best understood as a straightforward, low-barrier VTU integration option for Nigerian developers and reseller-website operators who are comfortable with a manual, payment-gated onboarding process rather than instant self-serve signup, and who want a single provider covering airtime, data, cable TV, electricity, and exam pins.

24. Peyflex API

Communications, Payments

Peyflex is a Nigerian VTU (Virtual Top-Up) and fintech platform operated by Peyflex Telecommunications Limited (RC 7796939), a private limited company registered with Nigeria's Corporate Affairs Commission in August 2024 and headquartered in Kakuri, Kaduna. Founded by Faith Amaole (Amaole Faith Adaeze), the company positions itself as unifying bills, data reselling, and related services into one platform for everyday users and resellers, available via its website and mobile app. Through its consumer platform, Peyflex offers mobile data bundle purchase/reselling (MTN, Airtel, Glo, 9mobile), airtime recharge, electricity bill/meter payments, cable TV subscriptions (GoTV, DStv, StarTimes), WAEC exam registration and result-checker PINs, betting account funding (e.g. SportyBet, Bet9ja-style platforms), cryptocurrency buy/sell, international data-only eSIMs, and virtual numbers for OTP verification. For developers and resellers, Peyflex provides a free 'Developer API' that lets third-party websites, apps, and reseller platforms integrate its VTU infrastructure directly. Access requires creating a Peyflex account, then generating a developer API token from the Developer API section of the user dashboard. As documented on Peyflex's Postman-hosted API reference, the API currently exposes endpoints for airtime top-up, data bundle purchase, cable TV subscriptions, electricity bill payment, exam PIN (ePIN) generation, and betting wallet funding; crypto, eSIM, and virtual-number endpoints are listed as 'coming soon' for the API even though those services exist on the main consumer platform. Peyflex markets the API as requiring no KYC to integrate or begin testing, and backs integration with a Postman documentation portal, an instructional video guide, and dedicated WhatsApp support (including account activation help and virtual meetings for developers who get stuck). Because pricing and discount tiers are built around reseller volume, the API is aimed primarily at Nigerian developers and resellers building their own VTU storefronts, bill-payment features, or fintech add-ons rather than at large-scale enterprise messaging or payment aggregation.

25. SME Plug API

Communications, Payments

SME Plug is a Nigerian Virtual Top-Up (VTU) and data automation platform based in Ibadan, Oyo State, that lets resellers, digital vendors, and developers programmatically distribute airtime, SME/gifting data bundles, cable TV subscriptions, electricity tokens, and bulk SMS to customers across MTN, Airtel, Glo, and 9mobile. For data delivery, SME Plug offers three operating models: an automated SIM system that dispenses SME and gifting data straight from a registered SIM without needing a running device, a device-based mode that vends data through a connected/active phone, and a wallet-based reseller mode that requires no direct vending hardware at all. The platform also supports auto-subscription for recurring data renewals and bulk vending to many phone numbers in a single request. On the API side, SME Plug publishes a Postman collection documenting Bearer-token authenticated REST endpoints for checking wallet balance, retrieving the list of supported networks, and purchasing data plans. Every request can trigger a transaction webhook, configured from the account settings dashboard, that notifies the integrator's server of success or failure with fields such as status, reference, customer_reference, transaction type, beneficiary, memo and price — removing the need to poll for transaction status. Beyond the documented data API, the wider SME Plug dashboard advertises airtime top-up, cable TV subscriptions (DStv, GOtv, Startimes), electricity bill payment (prepaid tokens and postpaid billing), bulk SMS from 2.5 kobo per unit, and flat-fee (₦25) inter-account bank transfers. The platform also includes reseller and staff account management with activity tracking and real-time sales analytics, making it geared toward Nigerian VTU resellers and small digital-service businesses as much as toward individual API integrators.

26. Paystack API

Payments, Development Tools

Paystack is Nigeria's most widely adopted payment gateway API and is a subsidiary of Stripe, the global payments infrastructure company that acquired Paystack in 2020. Founded in 2015 by Shola Akinlade and Ezra Olubi, Paystack was part of Y Combinator's 2016 batch and quickly became the default payment choice for Nigerian developers and businesses. The company is CBN-licensed and PCI-DSS compliant, and currently serves thousands of businesses across Nigeria, Ghana, South Africa, and Kenya. The Paystack API is RESTful and uses Bearer Token authentication. Every request must include an Authorization header with the format: Authorization: Bearer sk_live_xxxx (for production) or Authorization: Bearer sk_test_xxxx (for sandbox). API keys are obtained from the Paystack dashboard at dashboard.paystack.com. Paystack provides both public keys (used in client-side code to initialize the checkout) and secret keys (used server-side for all API calls). Developers must never expose the secret key in client-side code. The standard Paystack integration flow involves three steps: initialize a transaction server-side using the /transaction/initialize endpoint (passing email, amount in kobo, and optional metadata), redirect the user to the returned authorization URL or embed the Paystack inline popup using the JavaScript SDK, then verify the transaction on your server using /transaction/verify/:reference after the customer is redirected back. This three-step flow ensures transactions are validated server-side before fulfilling orders, preventing fraud and order manipulation. Paystack supports the widest range of payment channels of any Nigerian gateway: Verve, Visa, and Mastercard debit cards; bank transfer (pay by transfer); USSD (for customers without smartphones); mobile money (in Ghana); and QR code payments. The Paystack Checkout modal intelligently displays only the channels available for the customer's device and location. In terms of pricing, local card transactions cost 1.5% plus ₦100, capped at ₦2,000 per transaction. The ₦100 flat fee is waived for transactions of ₦2,500 or less. This means very small transactions (micro-payments) are effectively charged at 1.5% only. International card transactions cost 3.9% plus ₦100, with no cap. Bank transfers (receiving payments via bank account) are charged flat: ₦10 for amounts up to ₦5,000; ₦25 for ₦5,001 to ₦50,000; and ₦50 for amounts above ₦50,000. Outgoing transfers (disbursements) are: ₦10 for ₦0–₦5,000; ₦25 for ₦5,001–₦50,000; ₦50 for above ₦50,000. There are no setup fees and no monthly platform fees. Businesses processing more than ₦10 million per month are eligible for volume-based discounts by contacting Paystack enterprise support. The Paystack sandbox environment mirrors production exactly — all features available in live mode are available in test mode. This is a critical advantage for Nigerian developers who need to test subscription billing, split payments, and bulk transfers without using real money. Test mode uses test card numbers provided in the Paystack documentation and simulates bank transfer payments via a confirmation prompt. Paystack also provides a Subscriptions API that allows developers to create subscription plans with daily, weekly, monthly, or annual billing cycles. When a customer first pays, a subscription authorization token is generated and stored securely by Paystack. Subsequent charges happen automatically without requiring the customer to re-enter card details. This is the foundation for building SaaS billing, membership platforms, and digital subscription products in Nigeria. The Split Payments (multi-split) feature allows marketplace operators to automatically split collected revenue between multiple subaccounts at the time of transaction — specifying percentages or flat amounts for each recipient. This is commonly used by Nigerian food delivery platforms, logistics aggregators, and gig economy apps. The Bulk Transfers API enables disbursement to hundreds of Nigerian bank accounts in a single API call by submitting a list of transfer recipients. This is used for payroll, agent commissions, loan disbursements, and customer refunds. From a compliance standpoint, Paystack is PCI-DSS Level 1 certified — the highest level of payment card security certification. All card data is encrypted and processed on Paystack's infrastructure. Merchants are not required to be PCI-DSS certified themselves. Paystack operates under CBN supervision and complies with the Nigerian Data Protection Regulation (NDPR). Webhook events from Paystack must be validated using the HMAC-SHA512 signature sent in the X-Paystack-Signature header. Developers should validate this signature before processing any webhook event. Paystack retries failed webhooks for up to 72 hours. Known challenges for Nigerian developers: (1) International card transactions have no cap on the 3.9% fee — high-value international payments can be expensive. (2) Bank transfer payments can take up to 30 minutes during bank downtime, so developers must handle pending states gracefully. (3) BVN and NIN verification are not built into Paystack directly — these require Dojah or Smile Identity as a separate integration. Frequently Asked Questions: Can I use Paystack without a registered business? Yes — individuals can create a starter account and start accepting payments. However, you will need to provide CAC documents to unlock higher transaction limits and settlements. Does Paystack support USD payments? Paystack processes international cards in USD, but settlements are in NGN after conversion. USD settlement is available only for Paystack International accounts. Can I process recurring payments automatically? Yes — use the Subscriptions API to save a customer authorization token and charge them on any schedule automatically. Is the test environment exactly like production? Yes — Paystack test mode has full feature parity with live mode, including subscriptions, splits, and bulk transfers.

27. Bitget API

Blockchain, Trading & Currency Exchange

Global cryptocurrency exchange with institutional-grade APIs and liquidity tools. Bitget provides comprehensive trading APIs, white-label solutions, and institutional features for fintechs and businesses wanting to integrate crypto trading. Strong platform for building crypto trading applications and investment platforms.

28. Ciprand

Blockchain, Data Validation, Development Tools

Ciprand is a random data generation API hosted on RapidAPI that provides cryptographically secure random strings, passwords, UUIDs, and numeric values on demand. It eliminates the need for developers to implement custom random generation logic while ensuring the generated values meet security requirements for authentication tokens, invite codes, and test data. Security-sensitive applications require high-quality randomness that is unpredictable and non-repeating. Standard pseudo-random number generators in many programming environments are not cryptographically secure — they use deterministic algorithms that, given knowledge of the seed or sequence, could be predicted. For generating security tokens, one-time passwords, reset links, and API keys, cryptographically secure random generation is essential. The API accepts parameters specifying the desired output: string length, character set composition (alphanumeric, alphabetic only, numeric only, custom character set), number of results to return in a single call, and output format. This flexibility covers a wide range of use cases from simple random ID generation to complex password policies with specific character requirements. UUID generation produces universally unique identifiers in standard formats, suitable for use as database primary keys, correlation IDs in distributed systems, transaction identifiers, and any context requiring guaranteed uniqueness across systems and time. For Nigerian backend developers building authentication systems, random token generation is a recurring need. Password reset flows require generating unpredictable tokens with expiry. Email verification requires unique confirmation codes. Two-factor authentication generates one-time codes. API key provisioning requires unique, unpredictable key values. Ciprand handles all these scenarios with a single API call. Nigerian development teams that practice test-driven development benefit from random test data generation. Tests that use hardcoded values can mask edge case failures that only appear with certain input patterns. Using randomly generated test data at each test run exercises more of the input space and catches more bugs. Ciprand's API can generate random usernames, passwords, tokens, and IDs for test scenarios automatically. Nigerian SaaS platforms with referral programs, invitation-only access controls, or voucher systems need to generate large batches of unique, random codes. Ciprand's batch generation capability returns multiple random values in a single API call, making it efficient for bulk code generation operations. The API is hosted on RapidAPI, which provides a unified authentication layer via the X-RapidAPI-Key header. The RapidAPI marketplace also provides usage monitoring, rate limit management, and billing in a single dashboard — reducing the operational overhead of managing a separate vendor relationship. Nigerian developers already using RapidAPI for other services can add Ciprand without creating a new account. Integration is straightforward via standard HTTP GET requests. The response returns the generated random values as JSON, ready to use directly in the application workflow. Ciprand's alphanumeric generation with excluded-character support allows developers to specify characters that should be omitted from generated strings — useful for generating codes where visually ambiguous characters (0/O, 1/l/I) could cause human transcription errors. Nigerian platforms issuing readable codes that users must type manually (loyalty points vouchers, offline activation codes, support ticket IDs) benefit from excluding ambiguous characters for improved usability. The API's batch generation mode returns multiple unique random values in a single request, efficiently generating thousands of codes in one API call for bulk operations like voucher campaigns, loyalty point distributions, and access code provisioning.

29. CashEnvoy

Blockchain

CashEnvoy is one of Nigeria's earliest payment gateways, operated by E-Settlement Limited (ESL) and regulated by the Central Bank of Nigeria. The platform enables Nigerian merchants to accept online payments from customers using Nigerian debit cards (Verve, Visa, Mastercard), international cards, and the CashEnvoy wallet. The company claims to have processed over 10 million transactions and serves 5,000+ active merchants. What the API Does The CashEnvoy API enables developers to integrate payment processing into websites and applications, accepting NGN and USD transactions. Core capabilities include card payment acceptance (Verve, Visa, Mastercard), CashEnvoy wallet payments, and multi-currency support. The integration process is described as developer-friendly with API documentation provided through the merchant portal. How Developers Use It Developers create a merchant account at cashenvoy.com, obtain API keys from the dashboard, and integrate using the provided documentation. Authentication is via API key from the merchant dashboard. The API enables payment initiation, transaction verification, and merchant settlement processing. Pricing CashEnvoy does not publish its transaction fees publicly. As a CBN-regulated payment gateway, fees are likely in line with Nigerian payment industry standards. Contact CashEnvoy directly for current fee schedules. Compliance CashEnvoy is regulated by the Central Bank of Nigeria (CBN), which means it must comply with Nigerian payment system regulations, PCI-DSS standards for card processing, and merchant onboarding requirements including KYC for businesses. Challenges and Gotchas Important considerations: (1) CashEnvoy has a reported headcount of 1 employee as of early 2026 — this raises legitimate concerns about support responsiveness, active development, and long-term platform viability. (2) The platform is functional but far less actively developed than Paystack or Flutterwave. (3) API documentation is limited and not publicly accessible without account creation. (4) No support for newer payment methods like bank transfer checkout, USSD, or crypto. (5) Developers should carefully evaluate support SLAs and integration longevity before choosing CashEnvoy over more actively maintained alternatives. Company Background CashEnvoy was founded as one of Nigeria's early digital payment platforms and is operated by E-Settlement Limited. It was a notable player in the early Nigerian fintech ecosystem, predating the Paystack era. While the platform remains operational, it has not kept pace with the growth and feature velocity of newer Nigerian payment gateways. FAQs Q: Is CashEnvoy still active in 2026? A: The website is live and the API appears functional. However, the company reportedly has a very small team which may affect support and future development. Q: Does CashEnvoy accept Verve cards? A: Yes. CashEnvoy accepts Nigerian debit cards including Verve, Visa, and Mastercard. Q: What currencies does CashEnvoy support? A: NGN (Nigerian Naira) and USD are supported. Q: Should I use CashEnvoy for a new project? A: For new projects, consider Paystack or Flutterwave as primary options given their active developer ecosystems, robust documentation, and larger support teams. CashEnvoy may be suitable as a fallback or for specific existing integrations. CashEnvoy's wallet payment system complements card and bank transfer acceptance by allowing customers who have funded CashEnvoy wallets to pay merchants directly from their wallet balance. As an alternative payment method category, wallet-to-merchant payments reduce the friction associated with card entry for repeat customers who prefer stored payment methods. For Nigerian subscription services, recurring billing platforms, and marketplaces where repeat transactions are common, CashEnvoy wallet acceptance adds a payment option that returning customers may prefer over repeated card entry. For smaller Nigerian merchants and independent sellers who find leading payment gateways like Paystack or Flutterwave either difficult to qualify for or more feature-rich than their simple needs require, CashEnvoy provides a usable gateway option with straightforward onboarding and standard payment acceptance features. The competitive Nigerian payment gateway market means that having multiple provider options benefits merchants through pricing pressure and choice of provider based on specific feature, fee, or relationship preferences.

30. ComplyCube

Blockchain

ComplyCube is an ISO-certified cloud-based platform for automated Identity Verification (IDV), Anti-Money Laundering (AML) screening, and Know Your Customer (KYC) compliance workflows. Designed developer-first with a REST API, mobile and web SDKs, no-code integration options, and CRM connectors, ComplyCube enables businesses to build end-to-end identity and compliance workflows without requiring multiple vendor relationships. The platform covers over 220 jurisdictions and supports more than 10,000 document types, making it suitable for both Nigerian-focused deployments and multi-market expansions. Its transparent pricing model — where monthly subscription fees convert into a flexible credit pool usable across any check type, with billing only on successful verifications — makes it an attractive option for startups and growing businesses that want cost predictability. ## What the API Does ComplyCube provides the following core verification products: **Document Verification**: AI-powered analysis of government-issued IDs including Nigerian international passports, NIN slips, voter cards, and driver's licenses. The engine performs OCR extraction, security feature validation, tamper detection, and document template matching against its 10,000+ document library. **Biometric Liveness and Face Match**: Selfie-based face verification against the document photo, with passive and active liveness detection to confirm physical presence and prevent spoofing. **AML & Sanctions Screening**: Real-time and batch screening against OFAC, UN, EU, UK Treasury, and other global sanctions lists, PEP databases, and adverse media sources.

The platform supports FATF KYC/AML recommendations, EU AMLD5/6, FCA guidance, and applicable AML/CFT regulations globally. For Nigerian deployments, ComplyCube's check capabilities align with CBN Customer Due Diligence regulations. AML coverage includes OFAC, EU, UN, UK Treasury, and global PEP databases. ## Challenges & Gotchas for Nigerian Developers 1. **Credit pool management**: Monthly subscription fees become a credit pool — unused credits expire at the end of the billing period. Plan verification volume carefully to avoid wastage. 2. **Per-check pricing range**: The $0.10–$1.50 document check range varies significantly by document type and region. Confirm Nigeria-specific document check pricing in your plan. 3. **No native BVN verification**: ComplyCube does not directly integrate with NIBSS BVN data. Supplement with a dedicated Nigerian BVN API if required. 4. **USD billing**: ComplyCube charges in USD. Nigerian developers need a USD-capable payment method. 5. **NDPR considerations**: Biometric and identity data processed by ComplyCube falls under NDPR as sensitive personal data. Review the data processing agreement for Nigerian user data handling. ## Company Background ComplyCube is a UK-based company and ISO-certified compliance automation platform. It serves clients across banking, fintech, insurance, crypto, real estate, and gaming. The company is known for its developer-focused documentation, transparent pricing guides, and educational content around KYC API pricing best practices. ## Frequently Asked Questions **Q: Am I charged for failed verifications?** A: No. ComplyCube only charges credits for successfully completed verifications. **Q: Does ComplyCube support Nigerian identity documents?** A: Yes.

31. Vtunaija API

Education, Payments, Utility Tools

Nigerian VTU platform with comprehensive service coverage including airtime, data, bill payments, and exam pins. Vtunaija provides good customer support and developer-friendly APIs. Serves multiple needs beyond standard VTU including exam registration pin sales for JAMB, WAEC, and other educational institutions.

32. Covalent

Blockchain

Covalent provides a Unified API that abstracts blockchain data across more than 100 networks under a single, consistent API structure. Rather than building separate integrations for Ethereum, BNB Chain, Polygon, Avalanche, Arbitrum, Optimism, and dozens of other EVM and non-EVM chains, Nigerian developers can use one API with one key and one endpoint pattern to query any supported network. This dramatically reduces the development time for multi-chain applications — a growing necessity as Nigerian crypto users hold assets across multiple blockchains. Nigeria's crypto-savvy population increasingly operates across chains: trading on Ethereum DEXes, farming yield on BSC, minting NFTs on Polygon, and bridging assets between chains for better gas costs. Any application serving Nigerian users in 2024 and beyond must handle multi-chain data. Covalent is purpose-built for this use case — the same endpoint structure works across all chains, just by swapping the chain_id parameter. The Get Token Balances endpoint (/v1/{chain_id}/address/{address}/balances_v2/) is Covalent's signature feature. It returns every token held by a wallet address — native asset, ERC-20 tokens, and LP tokens — along with current USD prices, logos, and token decimals. For Nigerian wallet apps, this single endpoint can power an entire portfolio overview screen that displays all holdings with current values, without requiring separate price API calls or token metadata lookups. The Get NFT Balances endpoint returns all NFTs held by an address with full metadata: image URL, traits, collection name, floor price, and ownership history. For Nigerian NFT projects and marketplaces, this provides a complete NFT portfolio view without needing to query individual contract APIs or maintain a separate NFT metadata database. The Get Transactions endpoint returns the full transaction history for a wallet, enriched with decoded log events and value transfers. Covalent parses raw Ethereum log data into human-readable decoded events — for example, a Uniswap swap shows up as "Swapped 0.5 ETH for 900 USDC" rather than raw hex log data. This decoded enrichment makes it far easier for Nigerian developers to build transaction history displays. Class A endpoints (token balances, transactions, NFTs) are available on all chains. Class B endpoints provide protocol-specific data for major DeFi protocols: Uniswap, Aave, Compound, Curve, and others. These return user positions, liquidity pool data, and protocol-specific metrics that go beyond generic blockchain data. The Log Events by Topic Hash endpoint enables querying contract events across an entire blockchain by topic, with pagination — effectively enabling blockchain-wide event indexing without running infrastructure. Nigerian developers building analytics tools or protocol monitoring dashboards can use this to track all swaps on a DEX, all mints of an NFT collection, or all liquidations on a lending protocol. The free tier provides 100 requests per minute and covers all Class A endpoints. Premium plans starting at $99/month unlock higher rate limits, Class B DeFi endpoints at higher volumes, and dedicated support. Covalent's credit-based billing means complex queries that return large amounts of data cost more credits than simple queries, providing a fair usage model. API keys are obtained free at covalenthq.com, and no credit card is required to start building.

33. NodeReal

Blockchain, Development Tools

NodeReal is a blockchain infrastructure provider specializing in BNB Smart Chain with additional support for Ethereum, Polygon, and other chains. Backed by Binance and closely integrated with the BNB Chain ecosystem, NodeReal is the go-to choice for Nigerian developers building on BNB Smart Chain — offering the deepest BNB-specific tooling, enhanced BNB Chain APIs, and the fastest BNB node infrastructure due to proximity to Binance's own infrastructure. The platform provides 100 million compute units free per month, matching Alchemy's generous free tier for high-volume Nigerian applications. BNB Smart Chain is particularly relevant for Nigerian Web3 users because of its significantly lower transaction fees compared to Ethereum mainnet. While Ethereum gas fees can reach tens or hundreds of dollars per transaction during peak periods, BNB Smart Chain typically costs fractions of a cent — making DeFi, NFTs, and on-chain interactions accessible to Nigerian users who cannot afford Ethereum mainnet gas costs. Many Nigerian crypto applications choose BNB Smart Chain specifically for this cost accessibility, and NodeReal's BNB specialization makes it the optimal node provider for these deployments. Enhanced BNB APIs from NodeReal go beyond standard JSON-RPC to provide pre-indexed BNB Chain data — wallet transaction history, NFT portfolio data, account analytics, and token balances — similar to what Moralis or Alchemy enhanced APIs provide but optimized specifically for BNB Chain data. This eliminates custom indexing requirements for Nigerian applications building BNB Chain features. Archive node access enables historical state queries for any past block on BNB Smart Chain and Ethereum — essential for analytics applications, portfolio historical P&L calculations, and protocol audit tools that need to reconstruct past blockchain state. NodeReal's archive infrastructure is available on paid plans. The 100 million free compute units per month on the free plan is comparable to Alchemy's free tier, making NodeReal cost-competitive for Nigerian high-volume development. Paid plans at $99/month and above provide dedicated infrastructure with SLA-backed uptime for production deployments. For Nigerian developers building specifically on BNB Smart Chain, NodeReal combines the deep chain expertise of a specialized provider with Binance's infrastructure backing — a combination that delivers superior BNB Chain performance compared to generalist providers serving many chains with less per-chain optimization. NodeReal's Enhanced API goes beyond raw RPC by providing structured, higher-level endpoints for common blockchain data queries that would otherwise require multiple RPC calls and custom parsing. Transaction history by address, token balance queries, NFT metadata retrieval, and token transfer history are examples of Enhanced API capabilities that dramatically reduce the complexity of building blockchain-connected applications. The platform supports both BNB Smart Chain (the most widely used chain for DeFi in emerging markets due to lower fees) and Ethereum, making it particularly relevant for Nigerian Web3 projects targeting cost-conscious users who prefer BNB Chain's lower transaction costs over Ethereum's higher fees. For Nigerian Web3 projects building with BNB Chain — whether DeFi protocols, NFT marketplaces, or token-based loyalty programs — NodeReal provides the specialized infrastructure support for that ecosystem that general-purpose multi-chain providers cannot match. The combination of fast node access, enhanced APIs, and BNB Chain ecosystem expertise makes NodeReal a strong choice for BNB Chain-focused development. Monthly plans provide cost predictability for Nigerian development teams and startups managing their infrastructure budget, with clear upgrade paths as application traffic grows from development through production scale.

34. Bundle API

Blockchain, Payments

African crypto savings and investment platform with staking, savings products, and payment integrations. Bundle focuses on consumer-friendly crypto investment with some merchant and partner API capabilities. Enables users to save and invest in crypto with automated features and payment integration.

35. Ceviant Payments

Blockchain

Ceviant Payments is a dual-regulated payment infrastructure company holding both a CBN Payment Solution Service Provider (PSSP) licence in Nigeria and FCA registration (FRN: 712297) in the United Kingdom. The company also operates under HMRC Anti-Money Laundering regulations and complies with the Payment Services Regulations 2017. This dual regulatory framework makes Ceviant one of the few payment providers that can serve enterprise clients operating across both Nigerian and UK financial systems under a single infrastructure partnership. Ceviant is also PCI-DSS certified for card data security. What the API Does The Ceviant Pay API enables businesses to automate payment processing across multiple channels — domestic bank transfers, card payments, and enterprise disbursements. A key differentiator is Ceviant's direct API connectivity to banks in emerging markets, allowing clients to connect with banking services outside of traditional banking channels without multiple bilateral integrations. The API is designed for enterprise trust, security, and scale. How Developers Use It API developer access is not self-serve — developers must contact Ceviant directly through their developers page at ceviant.co/developers. Once onboarded, API credentials are issued for integration. The platform is REST-based with enterprise-grade security controls. A sandbox environment is available for testing. Pricing Enterprise pricing only — not publicly listed. Ceviant targets institutional and enterprise clients with custom contracts based on transaction volume and corridors. Contact Ceviant through their website for pricing. Compliance CBN PSSP-licensed for Nigeria, FCA-registered in the UK, HMRC AML-registered, and PCI-DSS certified. Ceviant's dual licensing is a significant advantage for businesses with cross-border Nigeria-UK operations. Challenges and Gotchas (1) Not self-serve — requires direct sales engagement before any API access. (2) No consumer-facing checkout widget or self-service integration. (3) Pricing is entirely opaque. (4) No crypto or USSD support — purely traditional payment rails. (5) Best suited for enterprise; not designed for small startup self-integration. Company Background Ceviant is registered in the UK and Nigeria (RC: 1904697 as Ceviant Payments Nigeria Limited). The company is backed by Launch Africa Ventures and targets enterprise financial institutions, banks, and large fintechs needing compliant cross-border payment infrastructure between Africa and Europe. FAQs Q: Is Ceviant regulated in Nigeria? A: Yes. Ceviant holds a CBN PSSP licence in Nigeria. Q: Can Ceviant process UK and Nigerian payments? A: Yes. Ceviant is dual-regulated in the UK (FCA) and Nigeria (CBN), making it suitable for cross-border GBP-NGN operations. Q: Is there a sandbox? A: Yes. A developer sandbox is available after onboarding. Q: Can a startup integrate Ceviant independently? A: Ceviant is primarily enterprise-focused. Self-service API access is not available — contact their team directly. Ceviant's dual regulatory positioning — CBN PSSP licensed in Nigeria and FCA registered in the United Kingdom — makes it particularly relevant for Nigerian businesses with UK operations or serving UK-based customers, and for Nigerian fintechs seeking regulatory credibility with international partners and investors. The combination of Nigerian and UK regulatory recognition provides a foundation for cross-border payment operations that many purely Nigerian-licensed providers cannot offer. Direct bank API connectivity in emerging markets, as provided by Ceviant, enables more reliable and lower-latency payment processing than gateway intermediaries by establishing direct relationships with correspondent banks in target markets. For enterprise clients processing high-volume transactions in African markets where indirect routing can add settlement delays and introduce additional failure points, direct bank connectivity improves both reliability and settlement predictability. For Nigerian fintechs and financial institutions seeking to establish correspondent banking relationships for cross-border payment services, Ceviant's enterprise infrastructure and dual regulatory standing provide a compliant pathway to international payment rails that individual Nigerian fintechs would find difficult to establish independently through direct bank relationship development.

The API provides full programmatic access to spot trading, order management, portfolio querying, and real-time market data through REST endpoints and WebSocket streams. Coinbase is a publicly listed company (NASDAQ: COIN) subject to US financial regulations, making its API the preferred choice for developers and institutions who need a highly compliant, US-regulated exchange as their trading infrastructure. Nigerian developers should note clearly that Coinbase does not support Nigerian users — Nigeria is not included in Coinbase's list of supported countries, and Nigerian residents cannot create Coinbase accounts, make deposits, or trade on the platform. This API entry is documented for completeness and for Nigerian developers who may be building applications for non-Nigerian markets. For Nigerian-focused exchange integrations, Busha Commerce API, Quidax, or other locally available exchanges are more appropriate. For developers working in supported regions, the Coinbase Advanced Trade API replaced the legacy Coinbase Pro API and provides enhanced features for algorithmic trading, portfolio management, and market making. The Advanced Trade interface includes advanced order types such as limit orders, stop orders, and bracket orders — tools that professional traders and algorithmic systems require for sophisticated execution strategies. Market data endpoints are publicly accessible without authentication. The GET /api/v3/brokerage/market/products endpoint returns all available trading pairs with current prices, 24-hour statistics, and market status. The GET /api/v3/brokerage/market/product_book endpoint returns real-time order book depth for any product. These public endpoints can be used by anyone — including Nigerian developers building price comparison tools or market data dashboards for non-Nigerian users — without creating a Coinbase account. WebSocket streaming provides real-time data for market data subscriptions: price updates (ticker), order book changes (level2), and user-specific order and trade notifications (user channel). The user channel requires authentication and delivers real-time updates whenever an order is placed, filled, cancelled, or modified. For algorithmic trading systems, the WebSocket feed is essential for maintaining an up-to-date view of open orders and account state. Portfolio management endpoints allow querying account balances, open orders, order history, and filled trade history. The portfolio structure in Coinbase Advanced Trade supports multiple named portfolios within a single account, with the ability to allocate funds between portfolios. This is useful for developers building multi-strategy trading systems where different strategies should have separate fund allocations and P&L tracking. OAuth 2.0 support enables third-party applications to request permission to read portfolio data or even trade on behalf of users — the appropriate pattern for user-facing apps that do not want users to directly share API keys. A portfolio management app can use OAuth to request read-only access to a user's Coinbase balances and transaction history, displaying it alongside data from other accounts. The Coinbase Advanced Trade sandbox environment (api-sandbox.coinbase.com) provides a test environment where developers can simulate trading without real money. Test funds are available for placing test orders, testing WebSocket streams, and validating application logic before connecting to production.

38. MobileVTU API

Utility Tools, Payments

Simple REST API for Nigerian airtime and data top-up services. MobileVTU provides straightforward integration for developers looking for lightweight VTU capabilities. Focused on simplicity and ease of use with clear REST endpoints. Supports all major Nigerian telecom networks for quick integration.

39. VTpass API

Banking & Fintech, Development Tools, Payments

VTpass is a dedicated Value Added Services (VAS) platform providing a unified API for developers to natively integrate utility bill payments and digital services directly into their applications. The VTpass API enables automated airtime vending (MTN, Airtel, Glo, 9mobile), data subscription bundles, electricity bill payments across Nigerian DisCos, cable TV subscription renewals (DStv, GOtv, Startimes), and other utility services. Nigerian fintech apps, mobile money platforms, and business solutions use VTpass to offer comprehensive utility payment services without building separate integrations for each provider.

40. Partna API

Banking & Fintech, Payments

Partna is a Nigerian-founded fintech platform providing stablecoin payments and B2B payment infrastructure across Africa. The Partna API enables stablecoin transactions, fiat on/off-ramps, and B2B transfers. Nigerian businesses and fintech platforms use Partna for cross-border payments, B2B settlement, and stablecoin-based transactions with minimal friction.

41. DataVTU API

Payments, Utility Tools

Nigerian VTU platform specializing in cheap data packages alongside airtime, cable TV, and utilities. DataVTU is popular among Nigerian developers and resellers for competitive data pricing. Provides API access for airtime recharge, data bundles, cable subscriptions, and bill payments across all major networks and providers.

42. VTU.ng API

Payments, Utility Tools

Nigerian VTU (Virtual Top-Up) platform providing airtime, cheap data, cable subscriptions, and bill payments API. VTU.ng is very popular among Nigerian developers and resellers for its excellent rates, simple integration, and strong API. Supports all major telecom networks (MTN, Airtel, Glo, 9mobile) and cable providers.

43. Alpaca Crypto API

Blockchain, Trading & Currency Exchange

Alpaca is a US-regulated broker-dealer that provides commission-free trading APIs for both US stocks and cryptocurrencies through a unified REST and WebSocket interface. Alpaca's business model is built around empowering fintech developers and algorithmic traders with brokerage infrastructure — meaning the API is first-class and well-maintained, not a secondary feature of a retail trading platform. Alpaca is a popular choice for US-based developers building trading applications, robo-advisors, and algorithmic trading bots that require a regulated brokerage API. Nigerian developers and users should be clearly aware that Alpaca restricts account registration to the United States and a limited number of other eligible countries. Nigeria is not currently on Alpaca's list of supported countries, so Nigerian residents cannot open live trading accounts or fund accounts to trade real assets. This API entry is documented for completeness and for Nigerian developers who may be building applications for US markets, or who want to use Alpaca's paper trading environment for strategy development and testing purposes. For US-eligible developers, Alpaca's crypto trading API provides access to 25+ cryptocurrency pairs including BTC/USD, ETH/USD, SOL/USD, and other major assets. Commission-free trading means no per-trade fees eat into returns — particularly valuable for algorithmic trading strategies with many small orders. Alpaca routes crypto trades through multiple liquidity providers to seek best execution, and there is no minimum account balance requirement to start trading crypto. The paper trading environment is a critical differentiator: Alpaca provides a complete simulation environment that uses real market data but executes simulated trades with virtual money. The paper trading API is accessible to any developer who creates an Alpaca account — even developers from countries like Nigeria who cannot trade real assets can create a paper trading account for testing and development purposes. This makes Alpaca's paper trading useful for Nigerian developers validating trading strategy logic before deploying to a live exchange. The REST API for crypto covers order placement (market, limit, stop, and bracket orders), open order management, order history, position tracking, and account balance queries. The data API returns real-time and historical OHLCV price data for all supported crypto pairs, with multiple bar resolutions (1 minute, 5 minutes, 1 hour, 1 day). WebSocket streams deliver real-time quote updates, trade events, and account-level order fill notifications. The unified nature of Alpaca's API — covering both US stocks and crypto with the same authentication, endpoint patterns, and WebSocket infrastructure — is a significant advantage for multi-asset application developers. A portfolio management app can manage US equity and crypto positions simultaneously through one API integration, with consistent data formats and authentication. Alpaca also provides a Broker API for platforms that want to offer trading capabilities to their own users — enabling fintech companies to build brokerage products on top of Alpaca's regulatory infrastructure. For US-based Nigerian-diaspora fintech founders building US financial products, the Broker API provides a path to offering both stock and crypto trading to US customers without applying for their own broker-dealer license. Paper trading remains the primary relevant use case for Nigerian developers — the free simulation environment with real market data is genuinely valuable for testing algorithmic trading systems, and the API structure is identical to production, meaning Nigerian developers can build and test complete trading bot implementations against real Alpaca infrastructure before considering production deployment in eligible markets.

44. Ivorypay API

Blockchain

Crypto payment API for accepting cryptocurrency payments and converting to local currency. Ivorypay enables businesses to accept crypto payments and settle in fiat across African markets including Nigeria. Bridges crypto and traditional banking systems.

45. Thunes Payout API

Blockchain

Thunes is a global B2B cross-border payments company headquartered in Singapore, operating a proprietary real-time payment network that connects over 12 billion bank accounts, mobile wallets, and stablecoin wallets across 140 countries — accessible through a single API integration. Unlike traditional correspondent banking, Thunes routes payments through direct partnerships with local payment providers, mobile network operators, and bank networks in each country, enabling real-time 24/7 fund disbursement without SWIFT delays. Thunes primarily serves enterprise clients: global marketplaces, gig economy platforms, remittance operators, global banks, and B2B payment networks. The company's API documentation is available at docs.thunes.com, and the platform is designed for high-volume institutional integrations rather than self-service individual developers. The Thunes API enables two core operations: payouts (sending money to recipients globally) and, more recently, collection (receiving payments). Payouts can be delivered to bank accounts, mobile wallets (MTN Mobile Money, M-Pesa, Orange Money, etc.), and stablecoin wallets (USDT, USDC) across 140 countries. Nigeria is accessible via bank account payouts and stablecoin disbursements. A significant 2026 product launch is Thunes' Instant Cross-Border Payout for Gig and Remote Workers — a direct-to-workforce solution that enables platforms to instantly pay remote workers and freelancers across 140 countries, 24/7, with funds delivered to bank accounts, mobile wallets, or stablecoin wallets in real time. For Nigerian gig workers receiving international payments, this means immediate access to earnings rather than 2–5 business day SWIFT settlement windows. Thunes differentiates on pricing transparency — the platform provides complete visibility on transfer fees, FX rates, and all associated costs before transaction authorization. This is in contrast to traditional remittance operators that often bundle fees into hidden FX spreads. For businesses sending high volumes of payments to Africa, the transparent fee model enables accurate cost forecasting. Authentication for the Thunes API uses an API Key provided after enterprise onboarding. All requests must be made over HTTPS. Webhooks are available for real-time transaction status updates. From a compliance standpoint, Thunes is regulated as a payment service provider in Singapore (MAS), the EU, and other jurisdictions. For Nigeria, Thunes routes payments through CBN-licensed local partners, ensuring regulatory compliance for inbound transfers. Thunes has strict AML/KYB requirements during onboarding — all partner businesses must complete full compliance verification before API access is granted. Frequently Asked Questions: Can I disburse to Nigerian bank accounts via Thunes? Yes — Nigeria is accessible via bank account payouts. The exact Nigerian bank coverage should be confirmed during Thunes enterprise onboarding. Does Thunes support USDT payouts to Nigeria? Yes — Thunes supports stablecoin payouts in USDT, which is particularly useful for serving Nigerian workers who prefer to hold USD-pegged stablecoins as a hedge against NGN devaluation. How does Thunes compare to Payoneer for Nigerian worker payouts? Payoneer requires workers to hold Payoneer accounts and withdraw manually. Thunes delivers directly to bank accounts or mobile wallets — no recipient account required on a Thunes platform. Thunes's stablecoin (USDT) payout rail to Nigeria represents an emerging payment corridor that bypasses traditional banking infrastructure for recipients who prefer or require cryptocurrency-based receipt. For Nigerian diaspora recipients, freelancers receiving international payments, and businesses with cryptocurrency treasury strategies, USDT payouts provide a settlement mechanism that is independent of CBN-regulated banking channels and traditional correspondent banking limitations. The 140+ country network coverage of Thunes means that Nigerian-focused platforms built on Thunes can serve Nigerian recipients specifically while the same integration handles payouts to recipients across Latin America, Southeast Asia, and other emerging market regions. For global platforms that include Nigeria among many operational markets, a single Thunes integration covers all markets simultaneously rather than requiring country-by-country payment provider relationships. Real-time payment tracking and delivery confirmation through the Thunes API allows platforms to verify that payouts have been received by recipient bank accounts or wallets, not just that the sending instruction was accepted. For platforms with customer service obligations around payment delivery — remittance services guaranteeing delivery within specific timeframes, gig platforms assuring workers that earnings are accessible — confirmed delivery status is operationally critical data.

46. Tendar API

eCommerce, Payments

Tendar is a Nigerian BNPL (Buy Now Pay Later) and lending platform providing APIs for e-commerce integration and installment management. The Tendar API enables merchants to offer BNPL checkout, manage installment plans, handle debt recovery, and embed flexible payment options directly into platforms. Nigerian e-commerce sites, marketplaces, and merchants use Tendar API to increase conversion by offering customers installment payment options.

47. Reloadly API

Utility Tools, Payments

Global VTU and mobile top-up API providing airtime and data recharge services across 130+ countries including Nigeria. Reloadly is excellent for international coverage with strong developer experience. Single API enables reaching customers across multiple countries and networks. Supports both global and Nigeria-specific mobile operators.

48. Brass API

Banking & Fintech, Payments

Business banking API for SMEs providing account management, payments, and financial services. Brass enables businesses to manage accounts, make transfers, and integrate banking features directly into their platforms. Designed specifically for SME needs with developer-friendly APIs.

49. SavePage.io

Blockchain

SavePage.io is a web page archiving API that captures and stores complete snapshots of web pages — including the full HTML source, rendered screenshots, and PDF exports — and provides permanent, stable permalink URLs for accessing the archived versions. Even if the original page is later modified, deleted, or taken offline, the archived version remains accessible via its permalink. The archiving process captures a comprehensive snapshot: the complete HTML including externally loaded resources, a rendered screenshot showing what the page looked like visually, and optionally a PDF version. Metadata including the capture timestamp, page title, and original URL is stored alongside the snapshot, providing essential context for archived evidence. Permanent permalinks are the key differentiator from simple screenshot tools. Each archived page receives a stable URL that never expires and remains accessible indefinitely. This permanence is what makes SavePage.io suitable for evidence preservation, compliance documentation, and legal proceedings — the archived record can be referenced in documents, submitted to courts, and accessed years after the original capture. For Nigerian legal professionals and legal technology platforms, web page archival has become increasingly important as disputes involving digital evidence — defamatory social media posts, fraudulent advertisements, misleading product claims, and contractual representations made online — become more common. Nigerian courts are increasingly accepting digital evidence, and archiving the original digital content at the time of discovery with a timestamped, verified archive service strengthens the evidential chain of custody. Nigerian fact-checking organizations, investigative journalists, and civil society monitors that document online misinformation, political statements, and corporate claims rely on web archiving to preserve evidence before subjects modify or delete their content. Automated archiving workflows built on the SavePage.io API enable systematic, time-stamped preservation of relevant content as it is discovered. Nigerian financial institutions, consulting firms, and corporate legal departments conducting due diligence on companies, individuals, and transactions need to document the state of publicly available information at the time of review. Archiving website content, company profiles, news articles, and regulatory filings provides a documented record of what was known and when. The API accepts a URL and returns an archived page ID and permalink. Subsequent calls can retrieve archive metadata and the archived content. Authentication uses an API key passed as a header or query parameter. The freemium pricing model makes basic archival accessible for small-scale use, with paid plans for higher-volume archival workflows. SavePage.io's API also supports querying archives by original URL — retrieving all archived versions of a specific URL created over time, enabling historical comparison of how a page has changed across multiple capture dates. Nigerian researchers monitoring how specific websites evolve over time — tracking changes to terms and conditions, product pages, or public statements — can use this capability to build change-detection workflows. Batch archiving mode allows submitting multiple URLs for archiving in a single API operation, which is efficient for Nigerian compliance teams or research organizations that need to archive large sets of related pages as a single workflow step — for example, archiving all pages on a specific website at a point in time for regulatory evidence. The archive timestamp and metadata returned by the API enable building tamper-evident audit trails — the capture timestamp combined with the content hash of the archived page provides cryptographic evidence that the content was captured at a specific time and has not been modified since archiving. Nigerian legal teams building evidence management systems can incorporate these timestamps into signed audit records for court submissions.

50. Providus Bank API

Banking & Fintech, Development Tools, Payments

Providus Bank is a fintech-friendly commercial bank providing Banking-as-a-Service (BaaS) APIs enabling fintech platforms to offer banking services. The Providus Bank API provides endpoints for transfers, virtual account creation, balance inquiries, statement retrieval, and webhook notifications. Nigerian fintech platforms, payment companies, and digital banks use Providus Bank APIs to enable core banking functionality, virtual account services, and fund management without building banking infrastructure.

51. Flutterwave API

Payments, Development Tools

Flutterwave is one of Africa's most widely used payment infrastructure companies, providing a comprehensive API that enables businesses to accept payments locally across Africa and internationally in 150+ countries. Founded in 2016 and headquartered in San Francisco with major operations in Lagos, Flutterwave powers payments for over 1.3 million businesses across Africa. The platform is CBN-licensed, PCI DSS Level 1 certified, and handles billions of dollars in transactions annually. What the API Does The Flutterwave API provides a unified payment layer covering: card payments (Verve, Visa, Mastercard, AMEX, Discover); bank transfer checkout (USSD and direct NIP); mobile money (M-Pesa, MTN MoMo, Airtel Money, and more); virtual accounts for NGN collections; recurring billing and subscription management; split payments for marketplace revenue sharing; bulk transfers for mass payouts; multi-currency settlement in NGN, USD, GBP, EUR, and more; and payment links for no-code collections. How Developers Use It Developers sign up at flutterwave.com, obtain API keys from the Developer section of the dashboard, and integrate using the documentation at developer.flutterwave.com. Authentication uses Bearer token — secret key placed as "Authorization: Bearer sk_test_..." in request headers. Test mode keys only work in the test environment. SDKs are available for JavaScript, React, React Native, Flutter, Python, PHP, Node.js, and more. Inline checkout and redirect checkout are both supported. Webhooks deliver real-time transaction events to developer endpoints. Pricing Local transactions (cards, bank transfer, USSD, POS, Visa QR): 2% per transaction, broken down as 1.4% transaction fee + 0.6% platform fee. International cards (Visa, Mastercard, AMEX, Discover): 4.8% per transaction. Transfer fees: ₦10 for transfers up to ₦5,000; ₦25 for ₦5,001 to ₦50,000; ₦50 for transfers above ₦50,000. All fees are subject to 7.5% VAT. No monthly fee — only pay when you transact. By default, customers bear transaction charges but this can be adjusted in the dashboard. Authentication Bearer token using the secret key from your Flutterwave dashboard. Format: "Authorization: Bearer sk_test_{KEY}" for test, "Authorization: Bearer sk_live_{KEY}" for live. Never expose secret keys client-side. Rate Limits Flutterwave enforces rate limits and returns HTTP 429 (Too Many Requests) when exceeded. Specific thresholds are documented at developer.flutterwave.com/v3.0/docs/rate-limit. Compliance CBN-licensed, PCI DSS Level 1 certified. Flutterwave is registered with multiple African central banks and financial regulatory authorities. NDPR-compliant for Nigerian data protection. Challenges and Gotchas (1) The 0.6% platform fee on top of the 1.4% transaction fee makes the effective local rate 2% — ensure pricing models account for both components. (2) 7.5% VAT applies to all fees, not just the base rate. (3) International card chargeback risk requires careful implementation of refund and dispute handling. (4) Flutterwave has faced some regulatory challenges historically — stay current on their operational status. (5) Webhook endpoint verification (signature check) is mandatory in production. Company Background Flutterwave was founded by Olugbenga Agboola (GB) and co-founders in 2016. The company has raised over $500M in funding and is valued at over $3 billion, making it one of Africa's most valuable fintech companies. It operates in 34+ African countries and has processed over $26 billion in transactions. FAQs Q: What is the fee for local card payments in Nigeria? A: 2% per transaction (1.4% + 0.6% platform fee), subject to 7.5% VAT. No cap publicly published — verify on the pricing page. Q: Does Flutterwave support USSD payments? A: Yes. USSD is supported at the same 2% local rate. Q: Does Flutterwave support M-Pesa in Kenya? A: Yes. M-Pesa is supported for Kenya and other East African markets. Q: Is there a sandbox? A: Yes. Use test mode API keys (sk_test_...) for sandbox testing. Q: What is the transfer fee? A: ₦10 for transfers ≤₦5,000; ₦25 for ₦5,001–₦50,000; ₦50 for transfers above ₦50,000. All subject to VAT.

52. Xpress Payment Solutions API

Payments

Payment API gateway for Nigerian merchants and developers. Xpress Payment provides payment processing, collections, and settlement services. Enables businesses to integrate payment capabilities into their platforms.

53. Unlimit (formerly CardPay)

Payments, Development Tools

Unlimit (formerly known as CardPay, then Unlimint) is a global financial technology company with over 15 years of experience in international payment infrastructure. Headquartered across multiple regional offices and operating in 200+ locations worldwide, Unlimit provides payment processing, multi-currency business accounts, Banking-as-a-Service (BaaS), and cryptocurrency on/off-ramp services to merchants, platforms, and financial institutions globally. Africa — specifically Nigeria, Kenya, and Tanzania — is explicitly listed as a supported region in Unlimit's global coverage. The company has undergone a notable branding evolution: originally known as CardPay, it rebranded to Unlimint, and subsequently to Unlimit (the current brand). Its core payment processing technology remains under the CardPay API specification (version 2.70), which continues to be used by integrators and is documented at integration.unlimit.com. The legacy GitHub repositories can be found under the "cardpay" organization on GitHub, reflecting the original brand. **Core Products** 1. **Payment Gateway** — Unlimit's flagship product: accepting card payments, local payment methods, and alternative payment methods (APMs) from customers in 200+ locations. The gateway supports over 1,000 payment methods — an exceptionally broad catalog that includes regional methods specific to Africa, Latin America, Asia-Pacific, Europe, and India. For Nigerian merchants, this means access to local Nigerian payment methods alongside international Visa, Mastercard, and Amex cards. The gateway supports both Payment Page Mode (where customers enter card details on Unlimit's hosted checkout page) and Gateway Mode (server-to-server, where the merchant's own application handles card data collection under PCI DSS compliance). 2. **Unlimit Accounts** — Multi-currency business accounts that allow businesses to hold, send, and receive funds in 30+ currencies. These accounts come with integrated card issuance for business spending and are accessible programmatically via API. For Nigerian businesses operating internationally, this provides a way to maintain USD, EUR, and GBP balances without going through traditional Nigerian commercial bank FX channels. 3. **Banking as a Service (BaaS)** — A white-label financial infrastructure layer that enables fintechs and non-bank businesses to offer card issuing, payment processing, and banking features under their own brand. The BaaS offering connects to SEPA (Euro transfers), SWIFT (international transfers), and BACS (UK transfers) payment rails. 4. **Unlimit Crypto** — An on/off-ramp service for crypto-native platforms: DeFi protocols, GameFi platforms, NFT marketplaces, and crypto exchanges can accept fiat currency from users and pay out in cryptocurrency (or vice versa) using Unlimit's crypto conversion infrastructure. **API Architecture & Authentication** The Unlimit (CardPay) API uses terminal-based credentials for authentication. Each merchant is assigned a Terminal Code and Password, which are used to generate SHA-512 HMAC signatures for request authentication — providing tamper-evident server-to-server authentication. OAuth 2.0 is used for certain API flows. The API has two primary modes: Payment Page Mode uses redirect-based flows, while Gateway Mode enables direct card processing on the merchant's own checkout page (requiring PCI DSS certification). The API is documented at integration.unlimit.com and legacy references appear on integration.unlimint.com (which redirects). **Sandbox Environment** Unlimit provides a sandbox environment for integration testing. Developers can simulate payments, test 3D Secure flows, and validate webhook integrations without processing real transactions. Sandbox credentials are separate from production credentials. **3D Secure & Fraud Prevention** Unlimit supports 3D Secure (3DS1 and 3DS2) for card authentication. In 3DS2 flows, Unlimit can collect additional customer authentication data either from the merchant's side or through an intermediate authentication page. This reduces chargebacks and strengthens payment security — particularly important for high-risk verticals like gaming, travel, and international e-commerce. **Recurring & Subscription Billing** Unlimit's gateway supports recurring payment schedules, making it suitable for subscription businesses that need to charge customers on weekly, monthly, or annual cycles without requiring manual card entry for each period. **Africa & Nigeria-Specific Context** Nigeria is one of three African markets explicitly listed in Unlimit's geographic coverage (alongside Kenya and Tanzania). For Nigerian merchants, this means Unlimit supports local Nigerian payment methods in addition to international cards. However, Unlimit is not a Nigerian-native payment provider — it is a global gateway that supports Nigeria as part of its multi-regional infrastructure. Businesses primarily serving the Nigerian domestic market may find Nigerian-native gateways (Paystack, Flutterwave) more deeply integrated with local payment methods and better suited to local developer support. Unlimit's strongest value proposition for Nigerian-connected businesses is multi-currency acceptance and serving international customer bases that include Nigeria. **Pricing** Unlimit does not publicly list pricing. Commercial terms are negotiated on a per-merchant basis depending on transaction volume, payment methods, geographic coverage, and vertical (gaming, travel, e-commerce, etc.). Merchants must contact Unlimit's sales team for pricing. This is typical for enterprise-grade global payment gateways. **Compliance & Licensing** Unlimit operates under financial services licenses in multiple jurisdictions. The company implements KYC and AML processes for merchant onboarding. Specific license details for Nigerian operations are not publicly disclosed — Unlimit operates as an international payment processor interfacing with Nigerian payment infrastructure rather than holding a direct CBN license. **Frequently Asked Questions** Q: Is Unlimit the same as CardPay? A: Yes. Unlimit was previously known as CardPay, then rebranded to Unlimint, and now operates as Unlimit. The core API documentation remains under the CardPay/CardPay API versioning. Q: Does Unlimit support Nigerian payment methods? A: Nigeria is explicitly listed as a supported market. Unlimit supports local Nigerian payment methods alongside international cards. Q: What is the difference between Payment Page Mode and Gateway Mode? A: Payment Page Mode redirects customers to Unlimit's hosted checkout for card entry. Gateway Mode processes card data directly on the merchant's site (requires PCI DSS compliance). Q: Is self-serve onboarding available? A: No. Merchant onboarding requires contacting Unlimit sales for custom pricing and a commercial agreement. Q: Does Unlimit support crypto payments? A: Yes. Unlimit Crypto provides on/off-ramp services enabling fiat-to-crypto and crypto-to-fiat conversions for DeFi, GameFi, and NFT platforms.

54. Jest

Development Tools, Blockchain

JavaScript testing framework with built-in coverage, mocking, and snapshot testing. Standard for Node.js and React testing in Nigerian development communities.

55. Kora Payments API

Payments

Kora (formerly Korapay) is a CBN-licensed pan-African payment infrastructure company offering a unified API for payment acceptance, payouts, identity verification, and exchange rates across Nigeria, Ghana, Kenya, and South Africa. The company rebranded from Korapay to Kora to signal its evolution from a single-market payment gateway to a multi-country API platform. Kora serves Nigerian and pan-African fintechs, marketplaces, and enterprises with a developer-first API design. What the API Does The Kora API provides: card payment acceptance (local and international); bank transfer checkout; mobile money payments across Africa; payouts to Nigerian and other African bank accounts; identity verification (BVN, NIN, vNIN, CAC, and multi-country KYC); a real-time exchange rate API; and webhook notifications for all transaction events. The API base URL is api.korapay.com/merchant. How Developers Use It Developers sign up at korahq.com, complete business verification, and obtain API keys from their Kora dashboard. Authentication uses Bearer tokens — the secret key is passed as "Authorization: Bearer {SECRET_KEY}" in request headers. Test mode uses separate test keys; live mode requires dashboard activation. Sandbox testing is available with specific test cards and bank account numbers. The full API reference is at developers.korapay.com and docs.korapay.com (OpenAPI spec available at developers.korapay.com/llms.txt). Pricing Not publicly listed. Per-verification costs for identity services are deducted directly from the Kora account balance. Payment processing fees require contacting Kora directly. Sandbox/test mode is free. Rate Limits Not publicly documented — contact Kora support for limits before high-volume integrations. Compliance CBN-licensed in Nigeria. Multi-country presence with appropriate regulatory relationships in Ghana, Kenya, and South Africa. Encryption and security-grade protocols for all identity verification calls. Challenges and Gotchas (1) Identity service activation is separate from standard payment access — must be enabled in dashboard. (2) No public rate card — pricing requires direct engagement. (3) Rate limits not documented. (4) Two documentation sites exist (developers.korapay.com and docs.korapay.com) — both are maintained but can cause confusion. (5) Recurring billing not currently supported. Company Background Kora was founded in Nigeria and has grown into a multi-country payment infrastructure provider. The company raised a Series A round and is backed by African and global investors. The rebrand from Korapay to Kora reflected the platform's expansion beyond Nigeria to serve pan-African payment flows. FAQs Q: Is Kora the same as Korapay? A: Yes. Korapay rebranded to Kora to reflect its multi-country expansion. Q: Does Kora support mobile money across Africa? A: Yes. Mobile money payments are supported across multiple African markets. Q: Is there a sandbox? A: Yes. Use test keys and the provided test card/bank account numbers to simulate payments. Q: Does Kora have an exchange rate API? A: Yes. A real-time exchange rate API is included in the Kora API suite. Kora's identity verification capabilities — BVN validation, NIN verification, CAC business registration lookup, bank account name resolution — allow platforms to perform KYC checks within the same API integration used for payments. For Nigerian fintechs with regulatory KYC obligations, combining payment processing and identity verification in a single provider relationship reduces integration complexity and the vendor management overhead of maintaining separate payment and KYC provider relationships. Multi-country coverage from Kora extends payment collection and disbursement capabilities to Nigeria, Ghana, Kenya, and South Africa through a single API, with exchange rate data available for FX conversion between these markets. Nigerian platforms expanding to other African markets, or pan-African platforms that include Nigeria as a market, can use Kora to cover multiple African payment contexts without establishing separate provider relationships in each country. Kora's API documentation and developer experience orientation reflect the company's positioning for developer-led product discovery — Nigerian developers can sign up, explore the sandbox, and begin integration without enterprise sales engagement. The availability of test environment credentials, comprehensive API reference documentation, and code examples reduces the time from developer discovery to working integration, which is meaningful for Nigerian startups moving quickly to market.

56. Zone (formerly AppZone)

Blockchain, Development Tools

Zone (formerly AppZone) is Africa's first CBN-licensed blockchain-based payment switching and processing company, founded by Obi Emetarom and headquartered in Lagos, Nigeria. In 2022, Zone became the first blockchain-powered fintech to receive a Payment Switching and Processing License from the Central Bank of Nigeria — a historically significant milestone that validated blockchain technology as a legitimate payment infrastructure layer under Nigerian regulatory oversight. Zone provides banks, fintechs, and financial service providers with simple APIs for processing a broad range of payment transactions through a decentralized blockchain settlement layer. Unlike traditional payment switches (NIBSS, Interswitch) that rely on centralized clearing databases, Zone's blockchain infrastructure creates an immutable, transparent ledger of every settlement — reducing reconciliation disputes and eliminating the need for a trusted central intermediary between participating institutions. The Zone API enables developers to process: account-to-account fund transfers, ATM card withdrawals, POS (Point of Sale) card payments, merchant web and in-app payments, cash-in/cash-out at agent locations, and cross-border remittances. These are the core transaction types that flow through any payment switch — and Zone's blockchain layer provides transparent audit trails for all of them. Currently, Zone is connected to more than 15 of Africa's largest commercial banks. The company's onboarding model is B2B partnership-driven — typically targeting banks, licensed payment service providers, and institutional fintechs rather than individual developers seeking self-service access. Integration is handled through a technical partnership agreement, which reflects the institutional nature of payment switching infrastructure. Zone raised a $8.5 million seed round in March 2024, backed by investors including Flourish Ventures and Speedinvest, to scale its decentralized payment infrastructure across Nigeria and expand to additional African markets. The company's pre-Zone identity as AppZone gave it over a decade of established relationships with Nigerian commercial banks — making it one of the most deeply connected fintech infrastructure companies in Nigeria. Authentication for Zone's developer APIs uses API Key or OAuth credentials obtained through the Zone developer portal. A sandbox environment is available for testing. Given the institutional nature of the product, developer access is typically preceded by a commercial engagement with the Zone team. From a compliance standpoint, Zone holds the CBN Payment Switching and Processing License — the highest-tier payment infrastructure license in Nigeria. This license covers all transaction types processed through the Zone switch. All participating banks and fintechs must themselves hold appropriate CBN licenses for their respective payment activities. Known challenges: Zone's developer portal and self-service documentation are less accessible than consumer-facing gateways like Paystack. The B2B, institution-first model means individual developers cannot simply sign up and start testing. Additionally, the blockchain infrastructure, while innovative, adds a layer of complexity compared to traditional switches — institutions must understand the settlement model before integration. Frequently Asked Questions: Is Zone's blockchain public or private? Zone operates a permissioned blockchain — only CBN-licensed institutions can participate as nodes. It is not a public blockchain like Ethereum or Bitcoin. Can I use Zone as a regular merchant to accept card payments? Zone is a payment switch, not a merchant payment gateway. It provides infrastructure to banks and fintechs, who then offer payment services to merchants. Contact a Zone-connected bank or fintech for merchant payment solutions. How is Zone different from NIBSS? NIBSS is a centralized clearing system owned by all Nigerian banks. Zone is a decentralized, blockchain-based switch that competes with NIBSS's NIP system — offering an alternative routing path for interbank transfers with blockchain-based settlement transparency.

57. Afriex API

Payments, Development Tools

Cross-border payment and remittance API for African businesses. Afriex enables payouts, collections, payment links, and customer management across multiple African corridors including Nigeria. Provides single unified API for international transfers to and from Africa with competitive rates and fast settlement.

58. Pocket Network

Blockchain, Development Tools

Pocket Network is a decentralized blockchain infrastructure protocol that provides RPC access to over 50 blockchains through a network of independent node operators rather than a centralized company. Unlike Alchemy, Infura, or QuickNode — where a single company operates the node infrastructure and can theoretically restrict access — Pocket Network is a blockchain protocol where thousands of independent node operators stake POKT tokens to serve RPC requests and earn token rewards. No single entity controls the network, making it structurally censorship-resistant. The philosophical distinction matters for Nigerian Web3 developers who value decentralization as a core principle. If Alchemy or Infura restricts API access (as has happened for specific use cases or regions in the past), applications depending on those providers go offline. Pocket Network's distributed architecture means no company has a master switch to turn off access — as long as the protocol and its independent node operators function, RPC access continues. For Nigerian developers building applications where this decentralization guarantee is important to their users or architecture, Pocket Network aligns with Web3 values more authentically than centralized providers. Access to Pocket Network for developers is simplified through the Grove Portal (grove.city), which provides free public endpoints for major chains (Ethereum, Polygon, Arbitrum, BNB Smart Chain, Avalanche, and others) without requiring account registration. For higher throughput, a Grove Portal account provides a dedicated API key with application-specific rate limits. The underlying Pocket Network protocol handles routing requests to node operators and distributing the work across the decentralized network. Coverage of 50+ blockchains includes Ethereum mainnet and testnets, Polygon, BNB Smart Chain, Arbitrum, Optimism, Avalanche, Solana, Harmony, and many others. Standard JSON-RPC compatibility means Pocket Network endpoints work as drop-in replacements for centralized providers in any Web3 application. For Nigerian developers who are ideologically committed to decentralization and want their application's infrastructure to reflect Web3 values throughout — not just the on-chain components — Pocket Network provides genuinely decentralized RPC infrastructure that is architecturally consistent with building truly decentralized applications. The Pocket Network gateway also provides access to specialized API features that go beyond basic JSON-RPC — including data retrieval optimization, request caching for frequently-accessed data, and rate limit management tools that help applications stay within their allocated usage while maximizing efficiency. For Nigerian Web3 developers concerned about infrastructure costs and vendor lock-in, Pocket Network's decentralized model offers an alternative to centralized providers like Infura and Alchemy. The network's tokenomics reward node operators for providing reliable service, creating economic incentives for quality infrastructure that are aligned with developer needs. Nigerian blockchain startups and DApp developers can use the Pocket Network gateway to access Ethereum and EVM-compatible chains reliably from day one of development, with a free tier that scales with early-stage usage and paid tiers that grow with the application. The decentralized architecture means there is no single provider that can terminate access, change pricing unilaterally, or experience centralized downtime. Pocket Network's decentralized architecture means Nigerian DApp developers are not subject to the Terms of Service restrictions that centralized providers impose — Pocket Network's permissionless access aligns better with the censorship-resistant philosophy of Web3 development and protects against sudden access termination that centralized providers can enforce.

59. ErcasPay

Payments, Security

ErcasPay is a CBN PSSP-licensed, PCI DSS-certified, and NDPA-compliant multicurrency payment gateway built specifically for Nigerian businesses. The platform supports 8 currencies — NGN, USD, GBP, EUR, CAD, GHS, GMD, and KES — enabling Nigerian merchants to accept both local and international payments through a single API integration. ErcasPay processes transactions from 5,000+ businesses and has offices in Lagos, Abuja, and Ibadan. What the API Does The ErcasPay REST API enables developers to: initiate and process local card payments (Verve, Visa, Mastercard), bank transfers, USSD, and QR code payments; accept international card payments in 7 foreign currencies; issue and manage virtual account numbers for NGN collections; generate payment links; and create invoices. The API uses separate sandbox and live environments with distinct base URLs. How Developers Use It Developers create an account at ercaspay.com, obtain API keys from the dashboard under developer settings, and integrate using the documentation at docs.ercaspay.com. Authentication uses Bearer tokens with secret keys prefixed ECRS-TEST-SK (sandbox) and ECRS-LIVE-SK (live). Sandbox base URL: api-staging.ercaspay.com/api/v1. Live base URL: api.ercaspay.com/api/v1. All requests require Accept: application/json and Content-Type: application/json headers. Pricing Local transactions (cards, bank transfer, QR, USSD): 1.4% per transaction, capped at ₦2,000. International card transactions: 4.8% per transaction. International payments first settle to a USD wallet; conversion to NGN is triggered from there. A 10% rolling reserve is applied on international card transactions, held for 180 days — refundable if no chargebacks occur. No monthly subscription fee. Authentication Bearer token authentication. Secret key placed in the Authorization header as "Bearer {SECRET_KEY}". Separate keys for test and live modes. Keys managed from the ErcasPay Dashboard. Compliance CBN PSSP-licensed, PCI DSS certified, and compliant with the Nigeria Data Protection Act (NDPA). Multi-location presence in Lagos, Abuja, and Ibadan. Challenges and Gotchas (1) 10% rolling reserve on international card transactions held 180 days can be a significant cash flow constraint for new merchants. (2) International payments do not settle directly in NGN — they go to a USD wallet first. (3) No recurring billing or split payment support currently. (4) Rate limits not publicly documented — confirm with ErcasPay before high-volume implementations. Company Background ErcasPay is operated by ErcasPay Nigeria Limited, headquartered in Lagos with offices in Abuja and Ibadan. The company targets Nigerian businesses of all sizes needing a reliable, multi-currency alternative payment gateway. FAQs Q: What is the fee for local card payments? A: 1.4% capped at ₦2,000 per transaction. Q: Does ErcasPay support USSD payments? A: Yes. USSD is supported at the same 1.4% (capped ₦2,000) local rate. Q: What currencies can I accept through ErcasPay? A: NGN, USD, GBP, EUR, CAD, GHS, GMD, and KES — 8 currencies total. Q: Is there a sandbox? A: Yes. Sandbox at api-staging.ercaspay.com/api/v1 using ECRS-TEST-SK keys. Q: What is the rolling reserve? A: A 10% hold on international card transaction amounts, retained for 180 days. It is refunded in full if no chargebacks are filed during that period. ErcasPay's multi-currency acceptance — NGN plus USD, GBP, EUR, CAD, and additional international currencies — enables Nigerian merchants to accept payments from both domestic customers paying in naira and international customers paying in their home currency. This dual-currency capability in a single gateway integration eliminates the need for separate domestic and international payment gateway relationships, reducing integration complexity and ongoing vendor management for Nigerian businesses serving both local and global customer segments. PCI DSS certification at ErcasPay ensures that card data handling meets international security standards, protecting Nigerian merchants from the liability and reputational risk of card data breaches. For Nigerian SMEs that lack the resources to implement independent PCI compliance infrastructure, using a certified gateway like ErcasPay allows them to accept card payments within a compliant infrastructure environment without bearing the cost and complexity of independent certification.

60. Bybit API

Blockchain, eCommerce

Bybit is one of the top-5 cryptocurrency derivatives exchanges globally by trading volume, particularly renowned for its deep liquidity in Bitcoin and Ethereum perpetual futures. The Bybit V5 API provides a unified REST and WebSocket interface covering spot trading, perpetual futures, quarterly futures, options, and copy trading — all under a single API key and account structure. Nigerian traders who are active in crypto derivatives markets and Nigerian developers building trading tools for this community will find Bybit's API one of the most complete and well-documented exchange APIs available, with accessible account registration for Nigerian users. Nigeria's crypto trading community includes a sophisticated segment of derivatives traders who use perpetual futures to amplify returns, hedge spot positions, or profit from both rising and falling markets. Bybit is a preferred platform for these traders because of its deep order book depth (reducing slippage on large orders), competitive funding rates, and reliable execution during high-volatility periods. The Bybit API enables Nigerian developers to build trading bots, risk management tools, and analytics dashboards for this derivatives-focused community. The Bybit V5 API unified account model consolidates all product types — spot, derivatives, and options — under a single account with unified margin. This means a single API key can manage spot trades and perpetual futures positions simultaneously, with the margin balance shared across all positions. This unified approach simplifies multi-product trading systems compared to exchanges that require separate API keys per product type. Perpetual futures are Bybit's core product. Perpetual contracts do not expire — they mimic the price of the underlying spot asset through a funding rate mechanism where longs and shorts periodically exchange payments based on the premium or discount of the perpetual price relative to spot. The funding rate endpoint returns current and historical funding rates, which is critical data for Nigerian derivatives traders calculating the true cost of holding leveraged positions. The order book WebSocket stream delivers real-time order book snapshots and incremental updates for all trading pairs. For Nigerian algorithmic traders who need microsecond-level order book data to implement market-making or statistical arbitrage strategies, Bybit's WebSocket infrastructure provides the data throughput needed. The REST order book endpoint provides depth snapshots for up to 200 levels per side. Copy trading is a distinctive Bybit feature that allows less-experienced traders to automatically copy positions from top-performing "master traders." The Copy Trading API provides public data on master trader performance: total ROI, win rate, maximum drawdown, number of followers, and current open positions (with a delay). Nigerian fintech applications targeting retail investors can use this data to build copy trading recommendation engines or performance comparison tools. Options trading on Bybit covers BTC and ETH options with standardized expiry dates. The options API returns the full options chain — available strikes and expiries, current bid/ask prices, implied volatility, and Greeks (delta, gamma, theta, vega). For Nigerian options traders or risk management tools, this data enables sophisticated derivatives analysis. The Bybit Testnet (testnet.bybit.com) provides a complete simulation environment where Nigerian developers can test trading bot logic, order management, and WebSocket connections without financial risk. Test funds are available from the testnet dashboard, and the testnet API is functionally identical to production for development purposes.

61. Exchangerate.host

Blockchain, Trading & Currency Exchange

Exchangerate.host is a free and freemium currency exchange rates API providing real-time and historical FX data for over 170 currencies including the Nigerian Naira, backed by multiple financial data sources and offering exceptional coverage breadth that spans traditional fiat currencies, precious metals, and cryptocurrency prices in a single unified API service. The API is particularly well regarded in the developer community for its generous free tier, which historically offered unlimited requests without rate limits. For Nigerian developers building applications with high currency conversion volumes — such as fintech platforms, e-commerce stores serving both local and international customers, or analytics dashboards showing FX trends — the ability to access live rates without per-query costs represents significant economic value, especially during the prototype and early growth phases where revenue is not yet sufficient to justify paid data subscriptions. The real-time rates endpoint fetches the latest exchange rates for all supported currencies relative to a specified base currency. Rates are updated multiple times daily from the aggregated financial market data providers that power the service. Nigerian applications displaying live Naira exchange rates against USD, EUR, GBP, and other currencies can rely on Exchangerate.host for current rate data that accurately reflects prevailing market conditions. Historical data access extends back years, enabling trend analysis and retrospective financial calculations. For Nigerian businesses reconciling multi-currency accounts, calculating the historical Naira value of foreign currency assets and transactions, or analyzing how the Naira has performed against trading partner currencies during specific economic periods, historical rate lookups are an essential feature. The API supports specifying any past date to retrieve the exchange rates that were in effect on that day. Cryptocurrency rate coverage sets Exchangerate.host apart from traditional fiat-only currency APIs. The API includes prices for Bitcoin, Ethereum, and hundreds of other cryptocurrencies converted to fiat currencies, enabling developers to display crypto-to-Naira conversions or integrate crypto pricing into the same FX data layer used for traditional currencies. For Nigerian fintech applications serving both traditional banking customers and crypto-aware users, consolidating fiat and crypto rates through a single API simplifies integration significantly. Precious metals prices are included alongside fiat and crypto rates. Gold, silver, platinum, and palladium prices are expressed in terms of currency units per troy ounce, enabling applications to display commodity prices alongside currency rates. For Nigerian investors tracking gold prices as an inflation hedge or investment tool, having gold prices available through the same API used for FX data is a convenient consolidation. Currency conversion is supported through a dedicated convert endpoint accepting source currency, target currency, and amount. This endpoint handles the calculation server-side, returning the converted amount and the rate applied. For applications that only need the conversion result rather than the underlying rate data, this endpoint minimizes response parsing complexity. Nigerian e-commerce platforms serving both the domestic market and the Nigerian diaspora in the UK, US, and Europe can use Exchangerate.host to display accurate Naira pricing to local customers while showing equivalent foreign currency prices to international visitors. Real-time rates ensure pricing remains accurate as the Naira exchange rate fluctuates, protecting businesses from pricing mismatches caused by stale rates. The API authenticates through an API key for the paid plans. The JSON response format is consistent and clearly documented with example requests available for all major programming languages. Paid plans unlock higher rate update frequencies, more historical data, and premium support, providing a clear upgrade path as applications grow from prototype to production scale.

62. Saleor API

eCommerce, Development Tools, Payments

Saleor is an open source, API-first headless e-commerce platform that exposes all commerce functionality through a GraphQL API. Unlike traditional e-commerce platforms that bundle a frontend and backend together, Saleor separates the commerce engine (API) from the presentation layer — enabling developers to build custom storefronts with any technology while the API handles all the complex commerce logic: products, inventory, pricing, discounts, orders, customers, payments, and fulfillment. The GraphQL API provides a typed, self-documenting interface to all commerce operations. Products and their variants (by size, color, or other attributes) are fully managed through the API, along with structured product metadata, category hierarchies, collection groupings, and media management. The inventory system tracks stock levels across multiple warehouses and automatically handles stock reservation during checkout. Order management through the API covers the full order lifecycle — from cart creation and checkout through payment capture, fulfillment assignment, shipping, and returns. The order events system provides a complete audit trail of every state change in an order, which is important for compliance and customer service in Nigerian e-commerce operations. The payment system is gateway-agnostic and plugin-based, allowing integration with any payment provider through a standard interface. For Nigerian e-commerce platforms, this means integrating Paystack, Flutterwave, or other Nigerian payment gateways through Saleor's payment plugin system — maintaining a unified order and payment record regardless of the payment provider used. Multi-channel commerce support enables a single Saleor instance to serve multiple sales channels (website, mobile app, marketplace) with different pricing, availability, and currency settings per channel. This is valuable for Nigerian retailers operating both domestic and export channels, or serving different customer segments with different pricing structures. For Nigerian technology companies building custom e-commerce solutions for clients — rather than deploying off-the-shelf platforms — Saleor provides a production-ready commerce API foundation that eliminates months of custom backend development. The MIT open source license means there are no licensing costs for self-hosted deployments, making it commercially viable for agencies building for Nigerian clients. Nigerian marketplaces and multi-vendor platforms can leverage Saleor's vendor management capabilities to manage multiple seller catalogs, configure commission structures, and route orders to the appropriate fulfillment party — all through the GraphQL API. Saleor Cloud offers a managed hosting option for teams that prefer not to run their own infrastructure, with a free development tier suitable for prototyping and a paid tier for production deployments. The self-hosted option via Docker is fully supported and provides complete control over the infrastructure. Saleor's storefront starter templates and SDKs for React, Next.js, and other frameworks accelerate the frontend development that sits on top of the GraphQL API. Nigerian agencies building custom e-commerce storefronts for clients can start from battle-tested starter code rather than building from scratch, focusing customization effort on the brand-specific design and functionality rather than boilerplate commerce logic. The permission system in Saleor uses fine-grained permissions for dashboard and API access — allowing Nigerian e-commerce operators to give warehouse staff access to order fulfillment features without exposing product pricing or customer data. This role-based access is important for Nigerian businesses with diverse staff roles accessing the same platform. Saleor's channel system supports multi-currency commerce natively, enabling Nigerian e-commerce businesses selling internationally to manage NGN pricing for domestic customers and USD or GBP pricing for export and diaspora markets through a single backend — with automatic currency-appropriate display based on the customer's channel.

63. Monica Blockchain APIs

Blockchain, Development Tools

Monica provides blockchain node access and payment infrastructure for African fintech companies. The platform is new in 2025/2026 bringing institutional-grade blockchain APIs to African developers. Monica is building the future of blockchain infrastructure for Africa. The service directly supports African blockchain adoption.

64. Crypto.com API

Blockchain

Crypto.com Exchange API provides programmatic access to one of the world's top-10 cryptocurrency exchanges, offering REST and WebSocket APIs for spot trading, derivatives, margin trading, staking data, and NFT marketplace interaction. Crypto.com is known for its deep integration between exchange services, a native blockchain (Cronos/CRO chain), and a comprehensive consumer product ecosystem including the Crypto.com App, Visa card, and NFT marketplace. For Nigerian developers and traders, the Exchange API provides access to all of these services programmatically, and Nigerian users can register on Crypto.com without reported geo-blocking. Nigeria's crypto trading community includes an active segment of users who hold and stake CRO tokens, attracted by the Crypto.com Visa card and staking rewards program. These users benefit from tools that give them more visibility and automation over their staking positions, trading activity, and NFT holdings than the standard app provides. The Crypto.com Exchange API enables building these custom tools — from automated trading systems to staking analytics dashboards to NFT floor price monitors. The Exchange API distinguishes between the Crypto.com Exchange (the institutional and advanced trading platform at exchange.crypto.com) and the Crypto.com App (the retail consumer platform). The API documented here refers to the Exchange. Both platforms share user accounts, but the API capabilities — including algorithmic trading, order book access, and WebSocket streams — are features of the Exchange platform. Market data endpoints return current prices, 24-hour statistics, order book depth up to 50 levels, and recent trades for all trading pairs. The REST API structure follows standard exchange conventions: GET endpoints for market data (no auth required), POST endpoints for trading and account operations (authentication required). Public market data is freely accessible, making it suitable for Nigerian price monitoring and comparison applications. Spot trading through the API supports market, limit, and stop orders for all listed pairs. The Exchange lists hundreds of trading pairs including BTC/USDT, ETH/USDT, CRO/USDT, and many altcoin pairs. Order placement, cancellation, and status checking follow standard patterns. The private API uses HMAC-SHA256 request signing with a nonce (millisecond timestamp) to prevent replay attacks. Derivatives trading on Crypto.com Exchange includes perpetual futures and quarterly futures for major cryptocurrencies, with leverage up to 100x for eligible accounts. The derivatives API follows similar patterns to the spot API but operates on the futures position and margin account. Nigerian traders using futures for hedging or speculation can manage their positions programmatically. The CRO staking data endpoints are particularly relevant for Nigerian users who hold CRO to access Crypto.com Visa card tier benefits or earn staking rewards. The API returns current staking positions, accumulated rewards, and unlock schedules — data that a Nigerian staking dashboard can display to help users track their passive income from CRO staking. NFT marketplace API access provides data on listed NFTs, recent sales, collection statistics, and bid activity on the Crypto.com NFT platform. Nigerian digital art collectors and creators who use the Crypto.com NFT marketplace can build custom alerting and analytics tools around this data. WebSocket channels deliver real-time data: ticker updates, order book changes, trade feeds, and user-specific order/trade notifications. The subscription-based WebSocket architecture is standard for high-frequency trading systems. A sandbox environment at uat-api.3ona.co is available for testing integrations without real funds, with simulated balances and trading capability.

65. CoinStats

Blockchain, Development Tools

CoinStats is a comprehensive cryptocurrency data and portfolio tracking API that aggregates market data from hundreds of cryptocurrency exchanges and blockchain networks to provide developers with real-time prices, portfolio analytics, DeFi yields, NFT data, and wallet tracking capabilities across over 120 blockchains and thousands of digital assets. The API serves as a centralized data layer for cryptocurrency applications, eliminating the need to build individual integrations with dozens of exchange APIs and blockchain nodes to access comprehensive crypto market data. By aggregating from multiple sources, CoinStats provides better price accuracy through cross-exchange averaging and ensures data availability even when individual exchanges experience downtime. For Nigerian crypto application developers, this aggregated approach is more reliable than depending on a single exchange's API. Cryptocurrency price data covers over 10,000 coins and tokens with current prices, 24-hour price change percentages, market capitalization, trading volume, and circulating supply. For each asset, price history is available at multiple time resolutions including minute, hourly, and daily intervals, enabling charts that display price movements over periods from the last hour to the full history of the asset. Nigerian crypto apps can display comprehensive market data for not just Bitcoin and Ethereum but the full spectrum of altcoins and DeFi tokens that Nigerian traders and investors hold. Portfolio tracking is a distinguishing CoinStats capability. The API enables applications to track a user's cryptocurrency holdings across multiple wallets and exchange accounts, calculating total portfolio value, individual asset allocations, profit and loss figures, and portfolio performance over time. Nigerian crypto investors who hold assets across multiple wallets — hardware wallets, software wallets, and exchange accounts — benefit from unified portfolio visibility in a single application rather than checking each account separately. Wallet analytics allows querying any public blockchain address to retrieve its current token balances, transaction history, and DeFi positions without requiring users to manually enter or update their holdings. For blockchains with public ledgers, users can add their wallet addresses to a CoinStats-powered application and receive automatic portfolio updates whenever they make transactions. This automatic synchronization removes the data entry burden from users and keeps portfolio data current without manual intervention. DeFi protocol data covers yield farming positions, liquidity pool holdings, and staking rewards across the major DeFi protocols on Ethereum, Binance Smart Chain, Polygon, Avalanche, and other networks. For Nigerian DeFi participants who have funds deployed in yield-generating protocols, seeing their DeFi positions integrated alongside regular crypto holdings gives a complete picture of their digital asset exposure and earnings. NFT data provides floor prices, collection statistics, and individual NFT valuations for major NFT marketplaces and collections. The growing Nigerian NFT creator and collector community benefits from applications that integrate NFT portfolio value alongside fungible token holdings. Exchange integration data covers trading pairs, order books, and trading volume from hundreds of cryptocurrency exchanges. Nigerian crypto traders who compare prices across exchanges to find the best execution can use this exchange data to build arbitrage monitoring tools or price comparison features. The API is available through a freemium model making it accessible to Nigerian developers at all stages. The CoinStats developer program provides documentation, sandbox access, and support for teams building crypto portfolio applications, trading tools, and DeFi analytics dashboards. Authentication uses API keys with clear rate limit tiers that scale with subscription level.

66. VelvPay

Development Tools, eCommerce, Payments

VelvPay is a Nigerian payment gateway built specifically for local businesses, freelancers, SMEs, and startups that need an affordable, easy-to-integrate payment solution without the complexity or pricing overhead of larger platforms. Positioned as "a rising star" in Nigeria's fintech ecosystem, VelvPay differentiates itself through transparent flat-rate pricing, same-day settlement, built-in invoicing tools, and a local-first approach to customer support that understands the specific needs of Nigerian merchants. **What VelvPay Does** VelvPay provides a multi-channel payment acceptance platform that covers web checkout, mobile app payments, and in-person transactions. At its core, the platform allows Nigerian businesses to accept card payments (Visa, Mastercard, Verve) and bank transfers from customers, with settlement directly to the merchant's Nigerian bank account. The platform is accessible both through a developer API for technical integrations and through a merchant dashboard with no-code tools for non-technical users. **Pricing — 1% Local Transactions** VelvPay charges 1% per local NGN transaction — one of the more competitive rates in the Nigerian payment gateway market. There are no hidden charges on top of this fee. For international transactions, VelvPay applies a flexible fee structure (specific rates are provided during merchant onboarding). No publicly advertised monthly subscription fee is required, making it a low-risk choice for businesses with variable or seasonal transaction volumes. For context, this 1% flat fee compares favorably to other Nigerian gateways that charge 1.5%–2.5% per transaction — a meaningful cost difference at scale, particularly for businesses processing high volumes of low-to-mid-value transactions. **Same-Day Settlement** VelvPay offers same-day settlement, which means payments collected on a given business day are available in the merchant's bank account on the same day (subject to cut-off times). This is a significant advantage for cash-flow-sensitive small businesses and freelancers who cannot afford to wait 1–3 days for funds to clear. **Invoicing Tools** Unlike most payment gateways that focus purely on API integrations, VelvPay includes built-in invoicing tools in the merchant dashboard. Businesses can create professional invoices with a payment link embedded directly — the client clicks "Pay Now" and completes the payment via card or bank transfer. This makes VelvPay accessible to freelancers, consultants, and service businesses that don't have a website or e-commerce store. **API & Developer Tools** VelvPay provides a REST API for developers who need to integrate payment acceptance into websites, mobile apps, or backend systems. API keys are issued after completing merchant onboarding. The API follows standard patterns with JSON request/response formats and webhook notifications for payment lifecycle events (payment initiated, payment successful, payment failed). Documentation is available through the VelvPay developer portal. **Multi-channel Payment Acceptance** VelvPay supports three primary payment channels: - **Web checkout**: A hosted payment page or embeddable checkout widget for websites and web apps - **Mobile**: SDK/API integration for iOS and Android mobile applications - **In-person**: Payment acceptance at physical locations for retail, market vendors, and hospitality businesses **Nigeria Focus & Support** VelvPay is built exclusively for the Nigerian market. Customer support is local and understands the operational reality of Nigerian businesses — from intermittent banking system downtimes to the preferences of Nigerian consumers for specific payment methods. This localization is a meaningful advantage for businesses that find the support teams of international platforms less responsive to Nigeria-specific issues. **Compliance** VelvPay operates within Nigeria's CBN regulatory framework for payment service providers. Merchant onboarding includes standard Nigerian KYC requirements (CAC registration, director ID, business bank account) to comply with CBN anti-money laundering directives. **Challenges & Limitations** VelvPay is smaller than market leaders Paystack and Flutterwave, which means its ecosystem of plugins, third-party integrations, and developer community resources is less extensive. Recurring/subscription billing and bulk payout APIs are not documented as current product features. USSD payments and split payment capabilities are also absent. For businesses that need deep payment infrastructure (marketplace payment splitting, cross-border payouts, card issuance), a larger platform may be more appropriate. However, for straightforward payment collection and invoicing in Nigeria, VelvPay's simplicity and pricing are competitive advantages. **Frequently Asked Questions** Q: What is the transaction fee on VelvPay? A: 1% per local NGN transaction with no hidden charges. International transaction fees are flexible — contact VelvPay for current rates. Q: Does VelvPay offer same-day settlement? A: Yes. Payments collected are typically settled to the merchant's bank account the same business day. Q: Do I need a CAC-registered business to use VelvPay? A: A CAC registration is required for production merchant access. Test/sandbox credentials can be obtained for development testing before completing KYC. Q: Does VelvPay support recurring billing? A: Recurring/subscription billing is not a documented current feature — use Paystack or SPay if you need automated recurring charges. Q: Is VelvPay available outside Nigeria? A: VelvPay is designed for the Nigerian market. Non-Nigerian businesses should explore international gateway options.

67. JuheAPI Dark Watermark

Development Tools, Payments

JuheAPI Dark Watermark API provides programmatic image watermarking capabilities, specializing in invisible and dark watermarks that embed ownership information into digital assets without visibly defacing the image. Unlike traditional visible watermarks that overlay logos or text on images, dark watermarking embeds ownership data in the image's pixel structure in a way that is imperceptible to the human eye but detectable by specialized software. The technology uses steganographic techniques to encode a creator identifier, timestamp, or custom payload within the frequency domain of the image data. When an image is suspected of unauthorized use, the dark watermark can be extracted and decoded to prove original ownership. This creates a digital provenance trail that is much harder to remove than visible watermarks, since removing it would require significantly degrading image quality. Visible dark watermark options (a lighter variant in the product line) add a subtle, semi-transparent mark to images that is noticeable to trained eyes but doesn't disrupt the primary visual experience of the image. This middle-ground approach is useful for watermarking preview images — images shown at reduced quality to potential buyers — where the watermark deters casual theft without completely obscuring the content that buyers need to evaluate. The API accepts standard image formats (JPEG, PNG, WebP) and returns watermarked versions with minimal quality loss. Batch processing support allows platforms with large image libraries to watermark multiple assets in a single API call, reducing integration overhead for bulk operations. The JSON response includes the processed image as a URL or base64-encoded data, along with metadata about the watermark that was embedded. For Nigerian photographers, media companies, stock photo platforms, and digital artists, the JuheAPI Dark Watermark API addresses a critical need: protecting creative work from unauthorized reproduction. Nigerian photographers who sell images online frequently face unauthorized use of their work — having an invisible ownership marker embedded in every image provides legal recourse and proof of ownership. Nigerian stock photo platforms can watermark preview images to deter theft while allowing legitimate buyers to download clean versions after payment. The extraction and verification process for dark watermarks requires matching software that can decode the embedded payload from a suspected unauthorized copy of the image. JuheAPI provides the companion verification endpoint — submitting a suspected copy of an image returns whether a watermark is detected and what ownership payload it decodes to. This creates a complete ownership claim workflow: embed the watermark, distribute the image, detect unauthorized copies, verify ownership with the extraction endpoint. For Nigerian legal contexts, digital watermark evidence has been used in intellectual property disputes to establish original ownership of photographs and artwork. Nigerian photographers who have had their images used without permission in advertisements or websites can use watermark extraction as documented evidence of their ownership in cease-and-desist communications or legal proceedings. The extractable payload typically contains a unique identifier that maps to a creator record in the developer's database, providing proof of provenance even if the image filename and EXIF metadata have been stripped. The JuheAPI platform provides a unified account and billing system across all their API products. Nigerian developers who use multiple JuheAPI services — including Web Summary and Dark Watermark — manage all API keys, usage quotas, and billing from a single dashboard. This consolidation simplifies vendor management and reduces the overhead of maintaining separate accounts and payment methods for each API service.

68. Fincra Identity

Identity & KYC, Payments

Fincra Identity is the identity management and verification feature set built into the Fincra API. It is not a standalone product — it is accessed using the same API credentials as Fincra payment services. Nigerian developers using Fincra for payments get identity verification capabilities included, enabling them to build compliant KYC flows without integrating a separate identity provider. What It Does Fincra Identity provides three core capabilities: (1) BVN Resolution — resolve a Nigerian Bank Verification Number to retrieve the associated identity details, enabling KYC verification against the CBN BVN database; (2) Bank Account Verification — verify that a Nigerian bank account number is valid and retrieve the account holder name via NIP lookup, preventing failed transfers before they happen; (3) Card BIN Resolution — look up a card BIN (Bank Identification Number) to identify the issuing bank, card network, card type, and country of origin for any card number prefix. How Developers Use It Fincra Identity endpoints are called using the same API key obtained from the Fincra Dashboard. Documentation is at docs.fincra.com under the Identity Management section. The same 50 req/sec rate limit applies. Sandbox and live environments are fully isolated as with all Fincra services. Pricing Included in the Fincra API subscription. Custom pricing based on volume — contact Fincra sales for current rates. Rate Limits 50 API calls per second, shared with all other Fincra API calls. HTTP 429 returned when exceeded. What Fincra Identity Does NOT Cover Unlike dedicated KYC providers such as Dojah, Smile Identity, or YouVerify, Fincra Identity does not provide: NIN verification, international passport verification, driver's licence lookup, liveness detection, document capture, or CAC business verification. For comprehensive KYC with selfie matching and multi-document support, a dedicated KYC provider is recommended. Challenges and Gotchas (1) Fincra Identity is only available to businesses that have an active Fincra account — you cannot use it without being a Fincra payments customer. (2) Feature set is narrower than dedicated KYC providers. (3) Live mode requires completing full Fincra compliance onboarding first. (4) No standalone pricing — bundled with Fincra payment costs. Company Background Fincra is a CBN PSSP-licensed payment gateway incorporated in the US (Fincra Inc.) and operating in Nigeria and across Africa. The company provides payment infrastructure to African businesses and fintechs, and includes identity verification as part of its end-to-end compliance toolkit. FAQs Q: Is Fincra Identity a separate product from Fincra payments? A: No. It is a feature set within the Fincra API accessed with the same credentials. Q: Can I use Fincra Identity without using Fincra for payments? A: Not independently — you need an active Fincra business account to access these endpoints. Q: Does Fincra Identity support NIN verification? A: Not currently. BVN resolution, bank account verification, and card BIN lookup are the currently documented identity features. Q: What is the rate limit? A: 50 requests per second, shared with all Fincra API calls. Fincra Identity's bank account verification feature resolves the account holder name associated with a provided Nigerian bank account number and bank sort code, confirming that the account belongs to the expected recipient before initiating a disbursement. This pre-disbursement verification step prevents both accidental wrong-account transfers (from typographical errors in account numbers) and deliberate fraud (where a bad actor substitutes their account number for a legitimate recipient). For Nigerian platforms processing large volumes of payouts — salary disbursements, vendor payments, refund processing — the operational cost savings from preventing failed and misdirected transfers justifies the verification step. Card BIN lookup from Fincra Identity allows platforms to identify the issuing bank, card type (debit/credit), card scheme (Visa/Mastercard/Verve), and country of origin from the first six digits of a card number before the transaction is processed. This BIN intelligence enables routing decisions — selecting the optimal payment processor for a card type, applying different processing flows for international versus domestic cards, flagging potentially high-risk card origins — that improve authorization rates and fraud management before authorization is even attempted.

69. Duplo

Development Tools, Payments, Banking & Fintech

Duplo is an API-first financial operating system for African businesses, providing a unified platform for B2B payments, expense management, virtual accounts, FX transfers, and NRS-compliant e-invoicing. Headquartered in Victoria Island, Lagos, Duplo is CBN PSSP-licensed, PCI DSS certified, ISO 27001 and 22301 certified, and NDPR-compliant. In early 2026, Duplo became one of the first Nigerian companies to secure dual NRS (Nigerian Revenue Service) licences for e-invoicing — a critical milestone as Nigeria moves toward mandatory digital invoicing for tax compliance.

72. Thirdweb

Blockchain, Development Tools, Payments

Thirdweb is a comprehensive Web3 development platform that provides the tools, infrastructure, and SDKs needed to build blockchain-powered applications — from wallet creation and smart contract deployment to NFT marketplaces, token launches, and backend transaction management. Unlike platforms that focus on a single aspect of Web3 development, Thirdweb covers the entire application stack: frontend wallet connection, smart contract deployment and interaction, backend wallet management, and payments. For Nigerian developers looking to build Web3 applications without needing years of blockchain expertise, Thirdweb dramatically lowers the barrier to entry. Nigeria's Web3 developer community is among the most active in Africa, with thousands of developers building NFT projects, DeFi tools, blockchain games, and tokenized platforms. The biggest challenge for Nigerian Web3 developers is not understanding the concepts — it is the steep learning curve of smart contract development, the complexity of wallet management, and the infrastructure required to support production dApps. Thirdweb abstracts all of this complexity into well-documented SDKs and APIs that work with familiar frameworks like React and Node.js. Embedded Wallets are Thirdweb's flagship feature for consumer applications. Instead of requiring users to have MetaMask or another browser wallet, Embedded Wallets create a Web3 wallet for any user who logs in with email, Google, Apple, or social accounts. The private key is secured in a distributed key management system and is recoverable via the same authentication method. For Nigerian consumer apps — e-commerce platforms with NFT loyalty rewards, games with on-chain items, content platforms with creator tokens — Embedded Wallets make Web3 accessible to users with no prior crypto experience. Smart contract deployment through Thirdweb's dashboard or SDK covers the most common contract types: ERC-20 tokens, ERC-721 NFT collections, ERC-1155 multi-edition tokens, Marketplace contracts (buy/sell/auction NFTs), Staking contracts, and more. These are audited, pre-built contracts that can be deployed in minutes from the dashboard — no Solidity knowledge required. For Nigerian project teams that want to launch an NFT collection or issue a utility token quickly, this eliminates weeks of smart contract development and security auditing. Account Abstraction (ERC-4337) support allows Nigerian developers to build gasless transaction flows where the application sponsors gas fees on behalf of users. This is transformative for user onboarding: a Nigerian user can interact with a blockchain application without ever buying cryptocurrency for gas fees. The application developer sponsors the gas, and users experience smooth, familiar web interactions rather than confusing wallet popups. Thirdweb Engine is a self-hosted or managed backend server that manages wallets and transactions at scale. For Nigerian applications that need to send thousands of transactions per day — airdropping tokens to users, minting NFTs on purchase, updating on-chain scores — Engine provides a reliable, queued transaction system with nonce management, retry logic, and webhook notifications. It eliminates the complex backend infrastructure that would otherwise be required for high-volume on-chain operations. The platform supports over 1,000 EVM chains, including Ethereum, BNB Chain, Polygon, Arbitrum, Base, and many others. Nigerian developers can build once and deploy to any chain without changing their application code. SDKs are available for TypeScript/JavaScript (React, React Native, Node.js), Python, Go, and Unity/Unreal for game development. The free tier is generous: 1,000 monthly active wallets and full access to smart contract tools, making it suitable for Nigerian projects in early stages and hackathons without any upfront cost.

73. Pairgate API

Payments, Utility Tools

Modern, developer-friendly Nigerian VTU platform providing airtime, cheap data packages, and bill payment APIs. Pairgate combines modern API design with competitive pricing. Designed with developers in mind, offering straightforward integration for airtime, data bundles, cable subscriptions, and utility payments across all Nigerian networks.

74. SPay Business Solutions

Payments, Development Tools

SPay Business Solutions Ltd is a Nigerian payment technology company offering a streamlined payment gateway designed specifically for Nigerian businesses, SMEs, freelancers, and service providers who need to accept online payments without complex infrastructure. Operating under the tagline "Payment Simplified!", SPay focuses on making payment collection accessible to businesses of all sizes — from solo freelancers generating payment links to online stores integrating a full checkout API. **What SPay Does** SPay provides a payment processing platform with four core capabilities: online payment acceptance, virtual account creation, payment link generation, and subscription/recurring billing management. These services are accessible via a RESTful API documented through readme.io, as well as via the SPay merchant dashboard for non-technical users who need payment links without coding. **Payment Acceptance API** SPay's payment API allows merchants to initiate payment sessions, redirect customers to a hosted payment page or embed a checkout widget, and receive payment confirmation via webhooks. The API handles both card payments and bank transfer acceptance, giving merchants multiple collection channels in a single integration. Standard REST API conventions are followed, with responses in JSON format and test payment tools provided for developer integration testing. **Virtual Accounts via First Bank of Nigeria** One of SPay's distinguishing features is its integration with First Bank of Nigeria for virtual account issuance. Merchants can programmatically create unique Nigerian bank account numbers (virtual accounts) that are tied to a specific customer or transaction. When a customer makes a bank transfer to the virtual account, SPay detects the payment in real time and notifies the merchant via webhook — enabling seamless bank transfer payment collection without manual reconciliation. This is particularly valuable for Nigerian consumers who prefer bank transfers over card payments. **Payment Links** SPay allows merchants to generate shareable payment links from the dashboard or via API — links that customers can open in a browser to complete a payment. This makes SPay accessible to businesses without a website, allowing freelancers, event organizers, and service businesses to collect payments via WhatsApp, email, or social media with zero code required. **Subscription & Recurring Billing** For SaaS products, membership platforms, schools, and subscription boxes, SPay offers a recurring billing module that handles automated charge schedules on weekly, monthly, or annual cycles. Merchants set up subscription plans, customers authorize the recurring payment, and SPay manages the billing cycle, retry logic for failed payments, and subscription lifecycle events. **Authentication** SPay uses API key-based authentication. Merchants receive API credentials (public key and secret key) after completing the merchant onboarding and KYC process on the SPay dashboard. API keys are passed in request headers for all API calls. Test mode credentials are provided separately and can be used to test integrations without processing real transactions. **Merchant Onboarding & KYC** To go live on SPay, merchants must complete a KYC process that includes providing business registration details (CAC certificate), bank account information for settlement, and identity verification for directors. This is standard practice for all Nigerian payment gateways operating under CBN regulatory requirements. Developers and businesses can test the API with test credentials before completing KYC — making it easy to build and validate integrations before going live. **Sandbox / Test Environment** SPay provides test payment capabilities for developers to simulate transactions and validate integrations without real money movement. The documentation on readme.io includes response codes and test scenarios. **Pricing** SPay uses a commission-based pricing model — merchants pay a percentage of each transaction processed. Specific fee percentages are not publicly listed on the website; merchants receive a pricing schedule upon completing merchant onboarding. No publicly advertised monthly subscription fee has been found. **Nigeria Context & Regulatory Standing** SPay is a Nigeria-focused payment company serving Nigerian merchants under CBN payment regulations. Banking partner arrangements, including the First Bank virtual account integration, operate within Nigeria's licensed payment infrastructure. SPay is suitable for Nigerian businesses that want a simpler, more focused payment solution compared to the complexity of larger platforms like Paystack or Flutterwave — particularly for businesses that primarily need virtual accounts and payment links rather than a full payments ecosystem. **Challenges for Nigerian Developers** SPay is a smaller gateway with fewer integrations and ecosystem tools compared to market leaders like Paystack or Flutterwave. The public documentation, while functional, is not as comprehensive or community-supported as larger platforms. Bulk payout/transfer capabilities, USSD payments, and POS integration are not available in the current product offering. International card acceptance (non-NGN) is also not documented as a supported feature. **Frequently Asked Questions** Q: Does SPay support USSD payments? A: No. SPay currently supports card payments and bank transfers via virtual accounts — not USSD. Q: Can I use SPay without a registered business (CAC)? A: A CAC-registered business is required for production access. Developers can test with sandbox credentials before completing KYC. Q: How are virtual accounts created through SPay? A: Virtual accounts are issued in partnership with First Bank of Nigeria via the SPay API — each account receives a unique Nigerian bank account number that customers can transfer to. Q: Does SPay support international payments? A: SPay is primarily focused on NGN payments for Nigerian customers. International card acceptance is not a documented feature. Q: Is there a recurring billing feature? A: Yes — SPay includes a subscription management module for automated recurring billing on daily, weekly, monthly, or annual schedules.

75. Dodo Payments API

eCommerce, Payments

Dodo Payments is a specialized Merchant of Record (MoR) platform built specifically for African SaaS, software, and online startups scaling globally. Unlike traditional payment gateways, Dodo Payments functions as the legal merchant of record, collecting international card payments from global customers, managing automated payout workflows, and completely handling global tax calculation and remittance obligations. This allows African software vendors and SaaS platforms to accept international payments and scale without the complex compliance and tax burden. Nigerian SaaS companies, software startups, and digital product creators use Dodo Payments to access international payment processing while Dodo handles all global tax and compliance responsibilities.

76. Persona

Identity & KYC, Development Tools, Payments

Persona is a flexible identity verification and compliance platform that enables businesses to build custom KYC (Know Your Customer) workflows combining government ID verification, biometric liveness checks, database lookups, phone/email verification, and AML screening — all configurable through a no-code workflow builder without requiring engineering changes for each compliance update. Founded in 2018 and headquartered in San Francisco, Persona serves fintech companies, crypto exchanges, marketplaces, lending platforms, and gig economy businesses globally. The platform is notable for its native Nigeria Database Verification module, which checks Nigerian NIN (National Identification Number), BVN (Bank Verification Number), voter registration cards, and driver's licenses directly against authoritative Nigerian government databases — a capability that distinguishes Persona from most global KYC providers who rely on document OCR alone without database cross-referencing. ## What the API Does Persona's API enables developers to trigger, manage, and retrieve identity verifications called "Inquiries." Each Inquiry runs a configurable set of verification steps: document verification (passport, national ID, driver's license), selfie liveness detection (passive or active), database checks (government, watchlist, phone, email), and business verification (KYB). For Nigerian users specifically, the Nigeria Database Verification product cross-references the user's submitted identity data against Nigerian government records, providing a higher-assurance confirmation than document image analysis alone. The platform's Workflow engine (formerly called "Cases") allows teams to define multi-step verification journeys with conditional logic. For example: if a user submits a voter card that fails OCR, automatically prompt for an alternative document; if a database check returns a sanctions hit, escalate to manual review; if transaction value exceeds a threshold, trigger enhanced due diligence. These rules are configured in Persona's dashboard without code. ## How Developers Use It Integration follows a standard flow: 1. Create an Inquiry using `POST /api/v1/inquiries` — this initializes a verification session for the end user. 2. Redirect the user to Persona's hosted verification flow (URL returned in the response) or embed using the Persona Embedded Flow SDK. 3. The user completes document upload, selfie, and any database check steps within the Persona-hosted UI. 4. Receive results via webhook (`inquiry.completed`, `inquiry.failed`, etc.) when the user finishes, or poll `GET /api/v1/inquiries/{inquiry-id}` for status. 5. Retrieve the full verification report including extracted data, check outcomes, and overall decision from the Inquiry object. Persona also provides a Verifications API for accessing individual check results (document verification report, database check report, selfie report) with granular pass/fail scores and extracted data fields. ## Pricing & Fees Persona uses a pay-per-successful-verification model — you are only charged when a verification completes successfully, not for failed or abandoned sessions. Plans include: - **Essential Plan**: $250/month (annual contract) — includes 500 verifications per month, $1 per additional verification. - **Growth Plan**: Custom pricing based on your verification volume and product mix. Recommended for most growing businesses. - **Enterprise Plan**: Fully custom pricing with dedicated support, SLA guarantees, and volume discounts. A sandbox environment is available immediately after signup for testing. ## Authentication Persona uses API key authentication. Your API key is passed as a Bearer token in the `Authorization: Bearer your_api_key` header on all requests. Persona API keys have environment scopes — sandbox keys work only against the sandbox environment, and live keys are used in production. Webhook payloads include an `X-Persona-Signature` header for payload verification to prevent forgery. ## Rate Limits Persona does not publish specific rate limits in their public documentation. Limits vary by plan tier. Contact Persona's support team to confirm the applicable rate limits for your subscription. ## Nigeria-Specific Capabilities Persona's Nigeria Database Verification is a standout feature for Nigerian developers. It covers: - **NIN Verification**: Cross-check NIN (National Identification Number) against NIMC database records. - **BVN Verification**: Verify the Bank Verification Number against NIBSS records. - **Voter Card Check**: Validate voter registration data against INEC records. - **Driver's License Check**: Verify driver's license data against FRSC records. This level of native database integration means Nigerian fintechs can achieve higher-confidence identity verification than document OCR alone, satisfying CBN's customer due diligence requirements for higher-tier accounts. ## Compliance & Regulations Persona holds ISO 27001 and SOC 2 Type II certifications. The platform supports GDPR, CCPA, and NDPR compliance. Verification workflows align with FATF KYC recommendations and CBN Customer Due Diligence regulations for Nigerian financial institutions. AML screening covers OFAC, UN, EU, UK Treasury, and global PEP databases. For Nigerian fintech clients, Persona's database verification checks provide evidence-based identity confirmation suitable for CBN KYC Tier 2 and Tier 3 requirements. ## Challenges & Gotchas for Nigerian Developers 1. **Nigeria database checks as add-on**: While Persona supports Nigerian database verification, it may be priced as an add-on module on top of the base plan. Confirm availability on your chosen plan. 2. **Essential plan volume limits**: 500 verifications/month on the Essential plan is modest. Growing Nigerian apps with significant onboarding volumes will need to move to Growth pricing quickly. 3. **USD billing only**: Persona charges in USD. Use a USD virtual card or wire transfer for payment. 4. **NDPR biometric data**: Selfie and biometric data captured during Persona verifications qualify as sensitive personal data under NDPR. Ensure your data processing agreement covers Nigerian user biometric data retention and deletion. 5. **Workflow complexity**: Persona's no-code Workflow builder is powerful but has a learning curve. Budget time for workflow configuration and QA testing before going live. ## Company Background Persona was founded in 2018 by Rick Song and Charles Yeh. The company has raised over $200 million in funding from investors including Index Ventures, Coatue, and First Round Capital. Persona is widely used by US and international fintech companies, and its Nigeria support makes it one of the few global KYC platforms with genuine database-level verification for Nigerian identity documents. ## Frequently Asked Questions **Q: Does Persona support Nigerian BVN verification?** A: Yes. Persona's Nigeria Database Verification product supports BVN cross-checking against NIBSS records, NIN against NIMC, voter cards against INEC, and driver's licenses against FRSC. **Q: Can I use Persona without a sales call?** A: Yes. The Essential plan ($250/month) activates after online signup. Growth and Enterprise plans require a sales conversation. **Q: Am I charged for failed verifications?** A: No. Persona only charges for successfully completed verifications — abandoned or failed sessions are not billed. **Q: Is there a free trial?** A: Persona provides a sandbox environment for testing without charge. Production verifications require an active plan.

77. CoinMarketCap API

Blockchain, Development Tools

CoinMarketCap is the most widely cited cryptocurrency market data platform in the world, providing real-time price data, market capitalisation rankings, trading volume, historical OHLCV (open, high, low, close, volume) charts, and comprehensive metadata for over 10,000 digital assets. Acquired by Binance in 2020 but operating independently, CoinMarketCap's API is the standard data source referenced by financial media, investment firms, academic research, and crypto applications globally. For Nigerian developers building crypto applications, CMC offers one of the most trusted and complete crypto data APIs with a usable free tier and affordable upgrades. Nigeria ranks among the top 10 countries globally for cryptocurrency adoption, driven by youth demographics, high smartphone penetration, and economic motivations including inflation hedging, cross-border payments, and investment diversification. Nigerian exchanges (Buycoins, Patricia, Roqqu, Breet), wallets, and fintech platforms all need reliable crypto price data. CoinMarketCap is the authoritative source for market cap rankings — which coin is #1, #10, #100 — and for current prices that Nigerian retail and institutional users expect to see when viewing their holdings. The /cryptocurrency/listings/latest endpoint returns paginated data for all cryptocurrencies ranked by market cap, with current price, 24-hour change, volume, and market cap in specified currencies. Passing convert=NGN returns all values denominated in Nigerian Naira, enabling Nigerian apps to display ₦-native pricing directly without requiring client-side conversion. The /cryptocurrency/quotes/latest endpoint returns real-time quotes for specific coins by symbol or ID — exactly what you need for a cryptocurrency price ticker component. The /cryptocurrency/ohlcv/historical endpoint provides daily OHLCV data for any asset over any historical range, the data foundation for rendering price charts. Combined with the /cryptocurrency/market-pairs/latest endpoint, developers can identify which exchanges are offering the best prices for a given asset and what trading pairs exist — valuable for arbitrage detection tools and smart order-routing systems. Global metrics endpoints return aggregate market data: total crypto market cap, Bitcoin dominance percentage, Ethereum dominance, active cryptocurrencies and exchanges, and DeFi-specific metrics. For Nigerian fintech dashboards and market research tools, these macro-level indicators provide the market context that sophisticated users expect. The Exchange endpoints cover hundreds of trading platforms, ranking them by volume, web traffic, and liquidity score. Nigerian crypto businesses can use exchange data to track competitor volumes, identify trending exchange platforms, and benchmark their own trading volumes against the broader market. CoinMarketCap's CMC200 index and CMC100 index data are available through the API, allowing Nigerian platforms to offer index-tracking investment products. The Trending endpoints surface the most-visited coin pages, fastest-rising coins, and most-watched coins — powering a "What's Trending" section in any Nigerian crypto app. The free Basic plan provides 333 API calls per day and 10,000 per month — sufficient for a low-traffic information site or prototype. The Hobbyist plan ($29/month) increases limits to 3,000 calls/day and enables more historical data endpoints. For production applications with significant traffic, the Startup ($79/month) and Standard ($299/month) plans provide the rate limits needed. Enterprise plans with custom limits are available for large Nigerian exchanges and financial institutions. A sandbox environment (sandbox-api.coinmarketcap.com) is available for all developers to test API integration without consuming production rate limits.

78. Chainlink

Blockchain

Chainlink is the world's most widely adopted decentralized oracle network, serving as the critical infrastructure layer that connects smart contracts to real-world data, external APIs, and cross-chain communication. Smart contracts on blockchains like Ethereum, BNB Chain, Polygon, and Avalanche are deterministic — they cannot access external data on their own. Chainlink solves this by providing a decentralized network of nodes that fetch external data, aggregate it, and deliver it on-chain in a tamper-proof manner. For Nigerian developers building DeFi protocols, NFT games, insurance products, or any smart contract application that needs external inputs, Chainlink is the industry-standard solution. Nigeria's emerging blockchain developer community is increasingly building production DeFi protocols, Web3 games, and tokenized asset platforms. Every DeFi lending protocol needs reliable asset prices to value collateral and trigger liquidations. Every on-chain game needs unpredictable randomness for fair outcomes. Every cross-chain application needs a trustworthy bridge. Chainlink provides all of these capabilities through a unified, battle-tested oracle infrastructure that has secured over $15 trillion in transaction value across DeFi. Chainlink Data Feeds are the most-used product — pre-deployed on-chain price feeds for hundreds of cryptocurrency and asset pairs including BTC/USD, ETH/USD, LINK/USD, USDC/USD, and many others. Reading a Chainlink price feed requires no API key or off-chain component — a smart contract simply calls the feed's latestRoundData() function to get the current price, timestamp, and round ID. These feeds are updated by decentralized networks of independent nodes that aggregate data from multiple premium data providers, making them highly manipulation-resistant. For Nigerian DeFi protocols, using Chainlink feeds rather than a single exchange price prevents flash loan price manipulation attacks. Chainlink VRF (Verifiable Random Function) provides cryptographically provable randomness to smart contracts. Each random number comes with a cryptographic proof that it was generated fairly and was not manipulated by the oracle, the developer, or anyone else. For Nigerian blockchain games, NFT mints with random trait assignment, and lottery applications, VRF is the only credible solution for on-chain randomness. The subscription model allows funding multiple VRF requests from a shared LINK balance. Chainlink Functions allows smart contracts to make requests to any external API and receive the response on-chain. A Nigerian agricultural insurance protocol can request weather data from a weather API, process it in a JavaScript function, and deliver the result to a smart contract to trigger automatic payouts. This transforms smart contracts from isolated blockchain programs into applications connected to the entire internet, while maintaining decentralized verification. Chainlink CCIP (Cross-Chain Interoperability Protocol) is the most secure cross-chain messaging and token transfer protocol available. CCIP allows sending tokens and arbitrary messages between blockchains through a risk management layer that independently monitors for anomalous activity. After multiple bridge hacks costing hundreds of millions of dollars, CCIP's defense-in-depth security model makes it the preferred choice for Nigerian developers building cross-chain applications that move real value. Chainlink Automation (formerly Keepers) enables automated smart contract execution — registering conditions that trigger contract functions without requiring a centralized server. Nigerian DeFi protocols can automate liquidations, yield harvesting, and rebalancing operations reliably through Chainlink's decentralized automation network. Development on testnets is free — Chainlink provides test LINK through faucets on Sepolia, Mumbai, and other testnets, allowing Nigerian developers to build and test complete oracle integrations without any cost before deploying to mainnet.

79. Alchemy

Blockchain, Development Tools, Payments

Alchemy is a blockchain developer platform providing managed node infrastructure, enhanced blockchain APIs, and developer tools for building Web3 applications on Ethereum and other major blockchains. Founded in 2017 and backed by leading Silicon Valley investors, Alchemy powers some of the most prominent DeFi protocols, NFT marketplaces, and Web3 applications globally. For Nigerian blockchain developers, Alchemy is a top-tier choice for node infrastructure with a generous free tier, comprehensive multi-chain support, and developer tools that significantly reduce the complexity of building production-grade blockchain applications. The core of Alchemy is managed blockchain node access. Rather than running and maintaining their own Ethereum or Polygon nodes (which requires significant server infrastructure, ongoing maintenance, and expertise in blockchain node operation), developers connect to Alchemy's distributed node network via API endpoints. Alchemy's infrastructure handles node synchronization, client diversity, load balancing, and uptime — providing Nigerian developers with institutional-grade blockchain connectivity from day one without infrastructure investment. Multi-chain support covers Ethereum mainnet and testnets (Sepolia, Goerli), Polygon (MATIC), Arbitrum, Optimism, Base, Solana, and other chains. This breadth is essential for Nigerian Web3 developers building cross-chain applications or choosing low-fee chains like Polygon for users sensitive to Ethereum gas costs. Nigerian users are particularly gas-cost-conscious, making L2 chains like Polygon and Arbitrum critical for applications targeting Nigerian Web3 users, and Alchemy supports all of these through the same developer account. Enhanced APIs are what differentiate Alchemy from simple node providers. The NFT API provides pre-indexed NFT data — fetching all NFTs owned by an address, NFT metadata, collection floor prices, and transfer history — without requiring developers to build custom indexing infrastructure. The Token API returns ERC-20 token balances, metadata, and price data for any wallet address. The Transfers API provides historical transaction history for an address across all asset types. These enhanced endpoints replace weeks of custom indexing work with simple API calls, dramatically reducing development time for Nigerian blockchain developers. Alchemy Notify provides webhook-based real-time notifications for blockchain events — address activity alerts, dropped transactions, mined transaction confirmations, and gas price alerts. Instead of polling the blockchain every block to check for activity, Nigerian applications subscribe to Alchemy Notify webhooks and receive POST requests when specified events occur. This is critical for fintech and payment applications that need to react immediately when transactions confirm. The Alchemy SDK (JavaScript/TypeScript and Python) wraps the standard JSON-RPC interface with a typed, developer-friendly API and automatically handles retry logic, rate limiting, and authentication. Nigerian developers can call the same ethers.js or web3.js methods they already know, with Alchemy SDK as a drop-in enhancement that adds reliability and the enhanced API endpoints. Free tier provides 300 million compute units per month — a generous allowance that covers typical development workloads and low-to-medium traffic production applications. There are no hard rate limits on the free tier (unlike many competitors that throttle requests per second), which makes Alchemy suitable for Nigerian developers building applications that may have bursty traffic patterns. Paid plans at $49/month and above provide higher compute unit allowances and enhanced support. For Nigerian Web3 developers, Alchemy is the standard starting point for Ethereum and EVM chain development. The combination of reliable node infrastructure, enhanced data APIs, real-time webhooks, and a generous free tier makes it the most developer-friendly and feature-complete option in the managed node provider space.

80. Dwellir

Blockchain, Development Tools

Dwellir is a specialized blockchain node infrastructure provider focused on the Polkadot and Substrate ecosystem. Unlike generalist node providers like Alchemy or QuickNode that serve primarily EVM chains, Dwellir specializes in Polkadot relay chain, Kusama, and the growing collection of Substrate-based parachains that make up the Polkadot ecosystem. This specialization means deeper technical expertise in Substrate node operation, better performance on Polkadot-specific RPC methods, and broader parachain coverage than generalist providers. For Nigerian Web3 developers building on the Polkadot ecosystem — whether on the relay chain itself, on Kusama (Polkadot's canary network), or on specific parachains like Acala (DeFi), Moonbeam (EVM-compatible), Astar (multi-VM), or others — Dwellir provides the specialized infrastructure needed to connect applications to these chains reliably. Polkadot's architecture differs fundamentally from Ethereum. Rather than a single monolithic blockchain, Polkadot consists of a relay chain coordinating security for many parallel chains (parachains), each with its own specific purpose and token economy. Building on this ecosystem requires connecting to specific parachain endpoints, and Dwellir maintains nodes for dozens of Polkadot parachains. Archive node access is available for queries requiring historical state data. WebSocket connections are the standard method for Polkadot/Substrate JSON-RPC communication, and Dwellir's infrastructure provides WebSocket endpoints for all supported chains. The @polkadot/api JavaScript library and Python substrate-interface use these WebSocket connections for all smart contract interactions, extrinsic submission, and state queries. For Nigerian developers who are specifically building in the Polkadot ecosystem, Dwellir is a focused provider worth evaluating. For those primarily building on EVM chains, the major EVM providers (Alchemy, QuickNode, Infura, Ankr) are more appropriate choices with broader EVM-specific tooling support. Dwellir supports multiple EVM-compatible chains alongside Substrate-based networks, enabling cross-chain application development from a single infrastructure provider. For Nigerian Web3 developers building DApps that need to interact with multiple chains, using a single provider simplifies API key management, billing, and support relationships. The free tier provides 500,000 requests per day — sufficient for active development, integration testing, and early-stage production deployments. Paid tiers scale to billions of requests per month for high-traffic DApps and institutional clients. Global load balancing across geographically distributed nodes ensures low latency for Nigerian users regardless of which specific server handles their request. Nigerian blockchain developers benefit from Dwellir's technical support and documentation, which are more accessible than running and debugging bare validator nodes. For developers entering the Polkadot ecosystem from Ethereum backgrounds, Dwellir's unified interface reduces the learning curve of connecting to unfamiliar Substrate-based networks. WebSocket endpoint support is essential for real-time DApp features — subscriptions to new block events, transaction status updates, and on-chain state changes. Dwellir's WebSocket connections are stable and managed, removing the operational complexity of maintaining persistent connection pools that would otherwise require custom infrastructure work from Nigerian development teams. Dwellir's transparent status page provides real-time and historical uptime information for each supported blockchain network, helping Nigerian developers monitor infrastructure health and plan maintenance windows. Reliable status communication reduces debugging time when connectivity issues occur.

81. GetBlock

Blockchain

GetBlock is a blockchain node provider offering shared and dedicated RPC node access for over 50 cryptocurrencies and blockchains with straightforward pricing and a clean developer experience. Founded in 2019, GetBlock has built a reputation as an accessible, budget-friendly node provider that covers the most commonly needed blockchains — Ethereum, Bitcoin, BNB Smart Chain, Solana, Polygon, Tron, and others — at prices significantly lower than premium providers like Alchemy or QuickNode for equivalent throughput. For Nigerian blockchain developers who are cost-conscious and need reliable multi-chain RPC without the premium pricing of top-tier providers, GetBlock offers a practical middle ground. The free plan (60,000 requests per day across all chains) is sufficient for active development and low-traffic production. Paid plans starting at $9/month provide substantially higher daily limits at prices that fit startup budgets. The API key authentication model is simple — a single API key provides access to all supported chains. Endpoint URLs follow the format: chain.getblock.io/API_KEY/mainnet/ (or testnet/ for test environments). This consistency simplifies multi-chain application configuration. WebSocket endpoints are available alongside HTTP for real-time subscription support. GetBlock covers the full standard JSON-RPC interface for each supported blockchain, meaning any code written for standard Ethereum RPC, Solana RPC, or Bitcoin Core RPC is compatible with GetBlock endpoints without modification. The drop-in compatibility allows Nigerian developers to switch to GetBlock from another provider or start fresh with well-documented standard methods. Shared node plans use pooled infrastructure where multiple users share node capacity, while dedicated node plans provide isolated infrastructure for production applications requiring guaranteed throughput. For Nigerian startups in early stages, shared nodes are cost-effective; for production applications with predictable high volume, dedicated nodes provide the reliability needed. GetBlock is a practical starting choice for Nigerian developers who want multi-chain access at minimal cost. GetBlock's multi-chain support spans over 40 blockchains including Ethereum, Bitcoin, BNB Smart Chain, Polygon, Solana, Avalanche, Tron, and many others — making it one of the broadest chain catalogs among node providers. This breadth is valuable for Nigerian Web3 developers building cross-chain applications or exploring multiple ecosystems without committing to separate providers for each chain. The free tier provides 40,000 requests per day at no cost, sufficient for development and light production use on a single project. Paid plans scale the daily request limit and add dedicated node access for applications requiring guaranteed performance without shared infrastructure limits. GetBlock's API follows the standard JSON-RPC protocol for each blockchain, meaning existing code written against other node providers works without modification when switching to GetBlock. For Nigerian developers migrating from other providers or using code examples from blockchain documentation, this compatibility reduces integration friction. Archive node access is available for chains that support it, enabling queries against historical blockchain state at any block height. This is essential for analytics applications, portfolio trackers, and compliance tools that need to reconstruct historical balances and transaction histories — common requirements for Nigerian fintech and investment platforms building blockchain data features.

82. Luno API

Blockchain, Trading & Currency Exchange

Popular global cryptocurrency exchange with strong presence across Africa including Nigeria. Luno provides trading APIs, market data endpoints, and wallet integrations for developers. Good for applications needing crypto trading capabilities and market data integration. Supports both beginner and advanced traders.

83. Payoneer Payout API

Payments

Payoneer is a global financial services company headquartered in New York that specializes in cross-border payments and mass payouts. Founded in 2005, Payoneer serves 5 million+ businesses and freelancers in 190+ countries, and is particularly popular in emerging markets including Nigeria, where it is widely used by freelancers, remote workers, and digital service providers to receive international payments from global clients on platforms like Upwork, Fiverr, and direct business clients. Payoneer is fully operational in Nigeria. Nigerian users can create Payoneer accounts, receive payments in USD, EUR, GBP, and other currencies, and withdraw directly to a Nigerian bank account in NGN. This makes Payoneer one of the most accessible international payment receipt platforms for Nigerian professionals. The Mass Payout API extends this capability to platforms — enabling businesses to disburse earnings to thousands of Payoneer account holders globally, including Nigeria, through a programmatic API. The Payoneer Mass Payout API v4 is RESTful with JSON payloads. Authentication uses OAuth 2.0 with Client ID and Client Secret, following the standard Client Credentials grant. API documentation is at developer.payoneer.com. The API enables platforms to: register new payees programmatically (white-label onboarding), check payee status and approval, initiate mass payouts to multiple payees in a single batch call, query payment status, and retrieve transaction history. The white-label registration flow is powerful for marketplace operators. Rather than requiring payees (freelancers, sellers, service providers) to manually create Payoneer accounts on Payoneer's website, the platform can embed a customized registration flow within their own UI — Payoneer handles the KYC verification in the background. This creates a seamless onboarding experience where users feel they're interacting with the platform's native payment system. Mass Payout batches allow platforms to submit hundreds or thousands of payment instructions simultaneously, specifying the Payoneer account ID and amount for each recipient. Payoneer processes these in batch and notifies the platform via webhooks on each payment's status (pending, processing, completed, failed). Pricing for Payoneer Mass Payout API is transaction-based. The fee structure depends on the payment type (Payoneer-to-Payoneer vs. Payoneer-to-bank), currency, and payout corridor. Payoneer-to-Payoneer transfers are typically free or very low cost. Bank withdrawals to Nigerian accounts incur conversion fees from the original currency (usually USD) to NGN. Exact rates are provided during the platform onboarding process and are negotiable for high-volume partners. From a compliance standpoint, Payoneer is registered with the US FinCEN as a Money Services Business and holds e-money licenses in the EU, UK, Japan, Australia, and other jurisdictions. For Nigeria, Payoneer operates under the CBN's guidelines for international remittance. The company went public on NASDAQ in 2021. Frequently Asked Questions: Can Nigerian individuals receive money on Payoneer? Yes — individual Nigerian professionals can create a free Payoneer account and receive USD, EUR, or GBP payments from international clients, then withdraw to a Nigerian bank. Can I build a platform that pays Nigerian sellers via Payoneer? Yes — use the Payoneer Mass Payout API with the white-label payee registration flow to onboard Nigerian sellers and disburse earnings to their Payoneer accounts (which they can then withdraw locally). Does Payoneer support NGN collections (receiving payments from Nigerian customers)? Primarily no — Payoneer is focused on paying OUT to recipients globally. For collecting NGN from Nigerian customers, use a local Nigerian gateway like Paystack or Monnify.

84. Ankr

Blockchain, Development Tools

Ankr is a Web3 infrastructure platform offering both free public RPC endpoints and premium dedicated node services for over 50 blockchains. Founded in 2017 and headquartered in San Francisco, Ankr operates a globally distributed network of blockchain nodes across multiple cloud providers and bare-metal servers, with a philosophy of decentralized infrastructure that reduces dependence on single providers. For Nigerian Web3 developers, Ankr is particularly valuable for its free public RPC endpoints that require no API key — making it the fastest entry point to multi-chain blockchain connectivity for development, testing, and early production use. The free public RPC endpoints are Ankr's most accessible offering. Developers can access Ethereum, Polygon, BNB Smart Chain, Avalanche, Fantom, Arbitrum, Optimism, Solana, and dozens of other chains without registering an account or obtaining an API key. The public endpoints are shared among all users and subject to shared rate limits, but they provide immediate connectivity for development work, hackathon projects, and low-traffic applications. For a Nigerian blockchain developer starting out, being able to connect to any major chain in seconds by simply specifying the Ankr public RPC URL in their Web3 library is a significant convenience. Premium endpoints provide dedicated node access with substantially higher rate limits, lower latency from dedicated infrastructure, and SLA-backed uptime guarantees. Premium accounts at Ankr are significantly less expensive than Alchemy or QuickNode for equivalent throughput on many chains, which has made Ankr popular for cost-conscious Nigerian teams scaling to production. Premium endpoints receive a unique API key embedded in the endpoint URL, isolating traffic from the public shared pool. Advanced APIs built on top of the node infrastructure provide pre-indexed blockchain data similar to Moralis — NFT API for wallet NFT portfolios, Token API for ERC-20 balances, and Query API for historical blockchain data. These enhanced endpoints are available on premium plans and eliminate the need for custom data indexing for common Web3 data patterns. The breadth of 50+ supported chains is one of Ankr's strongest selling points. Beyond the major EVM chains, Ankr supports many emerging chains (Gnosis, Celo, Aurora, Klaytn, Moonbeam, Telos, and many others) that are not covered by all node providers. For Nigerian Web3 developers exploring newer blockchain ecosystems or building cross-chain applications that span multiple less-common chains, Ankr often provides coverage that competitors lack. WebSocket endpoints are available for all supported chains on both public and premium tiers, enabling real-time blockchain event subscriptions for Nigerian applications requiring live data feeds, transaction monitoring, or event-driven smart contract interactions. Ankr's decentralization philosophy extends to its node operator network — Ankr allows independent node operators to join the network and serve requests, distributing infrastructure ownership beyond a single company. This aligns with Web3 values and provides a degree of censorship resistance that centralized node providers cannot offer. For Nigerian developers building applications that prioritize decentralization as a core value, Ankr's infrastructure model is ideologically consistent. Ankr also operates a liquid staking platform (ankrETH, ankrMATIC, etc.) that allows crypto holders to stake assets while maintaining liquidity — a DeFi product built on their node infrastructure. While this is not directly a developer API product, Nigerian developers building on Ankr's infrastructure benefit from working with a company that has deep stake in the blockchain networks they support. Pricing for premium endpoints is competitive, with monthly plans based on request volume rather than chain count — a single subscription provides access to all supported chains at the subscribed throughput level. This bundled pricing model is advantageous for Nigerian teams needing access to many chains simultaneously without paying per-chain fees.

85. Klasha API

Payments, Banking & Fintech

Klasha is a fintech platform providing global checkout solutions for African merchants enabling cross-border e-commerce payments. The Klasha API enables merchants to accept international payments, manage currency conversion, and simplify cross-border transactions. Nigerian e-commerce businesses and merchants use Klasha to expand internationally and accept payments from global customers.

86. Dynamic

Blockchain, Security, eCommerce

Dynamic is a Web3 authentication and wallet management platform built for product teams that want a polished, enterprise-grade user experience for wallet connection, embedded wallet creation, and Web3 user management. While other wallet connection libraries like RainbowKit and ConnectKit focus on the technical mechanics of wallet connection, Dynamic adds a full user management layer on top: analytics on user behavior, conversion tracking from visitor to connected wallet, allowlists, token gating, MFA, and a dashboard for managing your dApp's user base. For Nigerian Web3 startups and product teams that think seriously about user experience and product metrics, Dynamic offers capabilities far beyond basic wallet connection. Nigeria's Web3 user base is diverse — some users have MetaMask and hardware wallets, others are mobile-first users of Trust Wallet or Coinbase Wallet, and many are completely new to crypto and need embedded wallet creation via email or social login. Dynamic handles all of these users with one SDK. The wallet connection modal supports over 300 wallets and automatically detects which wallets are installed in the user's browser, presenting only relevant options and reducing confusion. Embedded Wallets in Dynamic create a self-custodial wallet secured by the user's email, Google, Apple, or other social authentication. The private key is managed through a distributed key system (similar to multi-party computation) that means no single server holds the complete key. Users can export their wallet's private key at any time, preserving true self-custody. For Nigerian consumer applications — e-commerce platforms, gaming, content monetization — embedded wallets convert any user into a Web3 participant without requiring any blockchain knowledge. Multi-Factor Authentication (MFA) is a security feature that Dynamic adds to Web3 wallets — something most wallet solutions omit. Nigerian businesses operating in regulated industries or handling high-value assets can require users to complete email or TOTP (Google Authenticator) 2FA before authorizing transactions. This adds a layer of security appropriate for Nigerian fintech and enterprise Web3 applications. Token and NFT gating allows Nigerian applications to restrict access to certain features, pages, or content based on on-chain ownership. A Nigerian DAO can gate its governance dashboard to holders of its governance token. A Nigerian creator can gate premium content to holders of their NFT collection. A Nigerian DeFi protocol can provide enhanced features to users holding more than a threshold of its native token. Dynamic's gating rules are configured in the dashboard without additional code. The User Management Dashboard gives Nigerian product teams visibility into their Web3 user base: how many wallets connected today, which wallet types are most popular, conversion rates through the onboarding funnel, and individual user activity. These analytics are typically absent from wallet connection libraries but are essential for product teams optimizing onboarding flows and retention. Webhooks allow Nigerian backends to receive real-time notifications when users connect wallets, complete authentication, or perform other events — enabling backend workflows like creating a database record for new users, triggering a welcome email, or updating a loyalty point balance when a wallet connects. The free tier supports up to 1,000 monthly active wallets — sufficient for Nigerian startups in early growth and hackathon projects. The Scale plan at $299/month supports up to 10,000 MAW with advanced analytics and priority support. Enterprise plans with custom pricing serve larger Nigerian Web3 platforms with compliance, SLA, and white-glove onboarding requirements.

87. Monnify

Payments, Development Tools

Monnify is a Nigerian payment gateway and payment infrastructure provider operated by Moniepoint Inc, a CBN-licensed payment solutions company and one of Nigeria's largest agent banking networks. Originally launched as a standalone product by TeamApt, Monnify was rebranded under the Moniepoint brand as the company expanded. Monnify provides Nigerian businesses with APIs for accepting payments via local debit cards, bank transfers, USSD, and direct debit, as well as disbursing funds to bank accounts across all Nigerian banks. The Monnify API is RESTful and uses JSON for all request and response payloads. Developers can authenticate using Basic Auth — by encoding the API key and secret key as a base64 string — or by exchanging credentials for an OAuth Bearer Token via the /auth/login endpoint. Most implementations prefer Bearer Token authentication for production use, obtaining a token at server startup and refreshing as needed. The Monnify dashboard is available at app.monnify.com and provides API credentials, transaction history, settlement reports, and webhook configuration. Payment collection works by initializing a transaction with a unique reference and an amount, then displaying the payment modal to the customer. The Monnify SDK handles the checkout experience, allowing customers to choose between card, bank transfer, USSD, or direct debit. For bank transfers, Monnify generates a reserved virtual account number for the customer — they transfer any amount to that account and the payment is automatically matched and settled to the merchant. This is particularly powerful for recurring or subscription-like payment flows. In terms of pricing, Monnify charges 1.5% per transaction for local card payments, USSD payments, and bank transfers, with a cap of ₦2,000 per transaction. An alternative flat fee of ₦500 may apply for certain bank transfer transactions. International card payments attract a 4% fee. Cash collection is also charged at 4%. There are no setup fees and no monthly platform fees. Payouts (disbursements to Nigerian bank accounts) are charged at flat rates: ₦10 for transfers below ₦10,000, ₦20 for transfers between ₦10,000 and ₦49,999, and ₦40 for transfers of ₦50,000 and above. All fees are exclusive of VAT. A key differentiator for Monnify is its settlement speed. Transactions are settled to merchants same-day by 10pm, and businesses can trigger up to 3 on-demand express settlements per day outside the standard settlement window. This is important for Nigerian e-commerce and service businesses that need immediate access to collected revenue. The Monnify sandbox environment is a full replica of the production environment. Developers can create a free sandbox account at developers.monnify.com without any business registration documents. The sandbox provides test card numbers, simulated bank transfer flows, and test USSD responses. Moving from sandbox to live requires completing the standard CBN KYC process, including submitting CAC documents, director BVN, and business bank account details. Rate limits for the Monnify API are not publicly published. However, for high-volume integration partners, Monnify support can provide guidance on expected throughput limits. The Webhook system sends real-time notifications for transaction completion, refunds, and disbursements — developers must validate the webhook hash to confirm the event originated from Monnify, and must respond with HTTP 200 within a defined timeout. From a compliance standpoint, Monnify is CBN-licensed and operates under the same regulatory framework as all Nigerian payment service providers. Moniepoint Inc holds a Payment Service Bank license and a Switching and Processing license from the CBN. Monnify is also PCI-DSS certified, which is required for handling card payment data in Nigeria. Merchants are not required to be PCI-DSS certified themselves, as card data is processed on Monnify servers rather than the merchant's infrastructure. The BVN verification endpoint available through Monnify allows developers to verify a customer's Bank Verification Number — returned with name, date of birth, and phone number — which is a CBN requirement for KYC compliance in lending and financial services. Common challenges Nigerian developers face with Monnify include webhook delivery delays during peak traffic (Black Friday, end-of-month), and the need to handle cases where bank transfer payments arrive outside the transaction expiry window. Developers should set generous expiry windows for bank transfer transactions, and use the transaction status query endpoint to confirm payment before fulfilling orders, rather than relying solely on webhook delivery. Moniepoint Inc, the parent company, is headquartered in Lagos, Nigeria and has expanded operations across several African markets. It was voted the fastest-growing company in Africa by the Financial Times in 2023 and has raised over $100 million in funding. Notable investors include QED Investors, Lightrock, and Google. The Monnify gateway is used by thousands of Nigerian businesses including e-commerce platforms, SaaS companies, and lending products. Frequently Asked Questions: Can I use Monnify without CAC registration? You can test the API freely on the sandbox with just an email. However, to go live and receive real settlements, full CBN KYC including CAC registration is required. Does Monnify support NGN only? Yes, Monnify primarily settles in Nigerian Naira (NGN). International card transactions are charged at 4% but are settled in NGN after currency conversion. Does Monnify have a no-code payment link? Yes, Monnify supports payment links and invoice generation from the dashboard — no coding required. What happens if my webhook fails? Monnify retries failed webhook deliveries. However, developers should use the transaction status API (/api/v1/merchant/transactions/query) as a fallback to confirm payment independently.

88. Chainstack

Blockchain, Payments, Development Tools

Chainstack is a production-grade blockchain infrastructure provider delivering managed RPC nodes, archive data access, real-time streaming, and dedicated node infrastructure across 70+ blockchain protocols. Designed for teams building multi-chain applications, trading systems, analytics platforms, and AI agents that need reliable, high-performance blockchain connectivity without the overhead of running their own nodes, Chainstack serves developers ranging from solo builders on a free plan to enterprise trading desks on dedicated infrastructure. For Nigerian Web3 developers, DeFi teams, and blockchain startups, Chainstack provides the node access layer that is the foundation of every blockchain application. Nigeria's growing blockchain developer community needs reliable, low-latency access to Ethereum, Solana, BNB Chain, Base, and other networks. Running your own blockchain node is impractical for most Nigerian startups — it requires significant cloud infrastructure costs, continuous maintenance, and weeks of initial chain synchronization. Chainstack eliminates all of that by providing managed, globally distributed nodes that Nigerian developers can start using in minutes with a free-tier API key. Chainstack provides RPC (Remote Procedure Call) endpoints for reading and writing to supported blockchains including Ethereum, Solana, Bitcoin, Base, Arbitrum, Polygon, Avalanche, and 65+ more. Key capabilities include: full node RPC for current-state queries; archive node access for complete historical data going back to the genesis block; WebSocket subscriptions for real-time event listening; Yellowstone gRPC streaming for ultra-low-latency Solana data (blocks, transactions, account changes); advanced token and NFT APIs; and global routing that automatically directs requests to the nearest region for the lowest possible latency. Archive node access is particularly valuable for Nigerian blockchain analytics companies and DeFi protocols that need historical data. A full node only stores the current blockchain state — it cannot answer questions about what an address's balance was six months ago. Archive nodes store every historical state, enabling queries like "what was the ETH balance of this address at block 15,000,000?" This historical data layer is essential for backtesting, analytics, and compliance workflows. The Yellowstone gRPC streaming interface for Solana is a premium capability that enables sub-millisecond data delivery for Solana-specific events: new blocks, new transactions, account state changes, and program-specific events. For Nigerian DeFi trading systems and MEV (maximal extractable value) infrastructure that operate on Solana, this real-time streaming is critical for competitive execution. Chainstack uses a Request Unit (RU) billing model rather than per-method pricing. Each API call consumes RUs from the monthly pool: full node requests cost 1 RU, archive requests cost 2 RU. This transparent billing means Nigerian developers always know exactly what their usage costs. The free Developer plan provides 3 million RUs per month with no credit card required — sufficient for building and testing most dApp features. Paid plans scale from Growth ($49/month, 20M RUs) through Pro ($199/month, 80M RUs), Business ($349/month, 140M RUs), and Enterprise ($990/month, 400M RUs with custom SLAs and dedicated infrastructure). Nigerian blockchain teams building production-scale applications — exchanges, wallets, DeFi protocols, NFT platforms — benefit from Chainstack's globally distributed node network. Chainstack operates nodes across multiple cloud regions, and its global routing automatically connects each request to the nearest available node. This reduces latency for Nigerian developers and their end users compared to a single-region node provider. For latency-sensitive applications like trading bots and real-time price feeds, this geographic distribution matters. Multi-chain support in a single platform is another key advantage. Rather than managing separate accounts and configurations across Alchemy (for Ethereum), Helius (for Solana), and other per-chain providers, Nigerian developers can manage all blockchain connectivity from Chainstack's unified dashboard. One account, one billing relationship, and one API key pattern across every supported chain simplifies developer operations for teams managing complex multi-chain infrastructure. Authentication uses API keys generated in the Chainstack dashboard under Settings. Keys are embedded directly in the RPC endpoint URL for most protocols, or passed as a header for HTTP-based requests. WebSocket connections include the API key in the WebSocket URL. No geo-blocking has been reported for Nigerian users — Chainstack is a global infrastructure provider accessible from Nigeria without restrictions. Sign up with an email address and the free Developer plan is immediately available with no credit card required.

89. Space and Time

Blockchain, Development Tools

Space and Time is a decentralized data warehouse purpose-built for Web3, combining the familiarity of SQL analytics with cryptographic verification of query results through a novel technology called Proof of SQL. The platform indexes blockchain data from Ethereum, Polygon, BNB Chain, Sui, Avalanche, and other networks into a high-performance columnar data warehouse, then allows developers and analysts to query that data using standard SQL. What makes Space and Time unique is that query results can be cryptographically proven — a zero-knowledge proof is generated showing that the query was executed correctly on the stated data, enabling smart contracts to trust off-chain computation results without re-executing them on-chain. For Nigerian Web3 developers, DeFi teams, and blockchain analytics companies, Space and Time addresses a fundamental challenge: complex analytics require processing large amounts of blockchain data efficiently, but doing that computation on-chain is prohibitively expensive. Space and Time's architecture performs the computation off-chain in a data warehouse (cheap and fast) while producing a ZK proof that the smart contract can verify on-chain (inexpensive to verify). This enables data-driven smart contract logic that was previously impossible. The SQL interface is a major advantage for Nigerian developers with traditional data or backend backgrounds who are entering Web3. Instead of learning blockchain-specific query languages or GraphQL schemas, developers can write familiar SELECT, JOIN, WHERE, and GROUP BY queries against indexed blockchain tables. A standard query against ERC-20 transfer tables can return all token inflows to a specific wallet address, grouped by token contract — exactly as you would query a relational database. This familiarity dramatically lowers the barrier for Nigerian developers transitioning from traditional backends to blockchain data work. Space and Time indexes pre-built datasets including ERC-20 and ERC-721 transfers, DEX swaps, liquidity events, lending protocol actions, and wallet-level activity. Nigerian analysts can immediately query these datasets without setting up indexing infrastructure. Custom table support allows importing off-chain data (from traditional databases, CSV files, or APIs) and joining it with on-chain data in a single SQL query — for example, joining a Nigerian exchange's internal user table with Ethereum transaction data to map on-chain addresses to known users. The smart contract integration layer allows dApps to request a query execution and receive the result along with a Proof of SQL delivered to a smart contract. This enables use cases like: dynamically adjusting DeFi interest rates based on verified TVL data, distributing NFT rewards based on proven on-chain activity scores, or triggering protocol governance actions based on verified market data. For Nigerian DeFi protocols building complex tokenomics or reward systems, this verifiable data delivery is transformative. Backed by Microsoft and with strategic investments from major blockchain investors, Space and Time represents a well-resourced bet on the future of verifiable blockchain analytics. The developer tier is available free to get started, with enterprise pricing for production-scale deployments. The REST API and gRPC interface make it compatible with standard developer tooling, and client SDKs are available for JavaScript/TypeScript, Python, and other languages. JWT-based authentication ensures secure, session-based API access. For Nigerian institutions, regulated entities, and serious Web3 projects that need auditable, tamper-proof analytics — not just data for display purposes — Space and Time's Proof of SQL makes it the most credible on-chain analytics platform available today.

90. The Graph

Development Tools, Blockchain

The Graph is the decentralized indexing and querying protocol for blockchain data, often described as "the Google of Web3." Instead of querying a blockchain node directly — which requires iterating through blocks and parsing raw event logs — developers deploy subgraphs that define how to index specific smart contract events, then query that indexed data using GraphQL. The result is fast, structured, and expressive querying of blockchain state that would be impractical or impossible with direct RPC calls alone. The Graph is the infrastructure layer behind Uniswap, Aave, Compound, ENS, Decentraland, and thousands of other DeFi and Web3 applications. For Nigerian Web3 developers, The Graph solves one of the most painful problems in dApp development: accessing historical and aggregated on-chain data. Querying "show me all swaps in the last 24 hours on this DEX" or "show me the trading volume history for this token" requires indexed blockchain data. Without The Graph, developers must either run their own indexing infrastructure (complex and expensive) or accept very limited blockchain data in their frontends. The Graph makes these queries as simple as writing a GraphQL query. Subgraphs are the core unit of The Graph. A subgraph manifest defines: which smart contracts to watch, which events to listen for, and how to transform those events into entities stored in The Graph's indexed data store. For example, a subgraph for a Nigerian DeFi protocol might define a Swap entity with fields for trader address, token in, token out, amount, and timestamp — indexed every time the protocol's Swap event fires. Once deployed, developers can query all swaps with filters, sorts, and aggregations using GraphQL. The Graph hosts thousands of pre-built subgraphs for major DeFi protocols. Nigerian developers building portfolio trackers, analytics tools, or integrations can query existing Uniswap, Aave, Compound, and Curve subgraphs immediately — no deployment required. The Uniswap v3 subgraph alone provides data for millions of liquidity positions, pool statistics, token prices, and historical swap data. Subgraph Studio at thegraph.com/studio is the development environment where developers create, test, and deploy subgraphs. It provides a GraphQL playground for testing queries, deployment tooling via the Graph CLI, and API key management. Development on the hosted service is free. When deploying to the decentralized network for production, queries are paid for in GRT (Graph Token) or through a USD billing account — costs are typically fractions of a cent per query for most use cases. The GraphQL API supports time-travel queries (querying state at a specific block number), entity relationships (joining data across multiple entity types in a single query), and real-time subscriptions (websocket subscriptions for live data updates). These capabilities make it possible to build sophisticated Nigerian DeFi dashboards, analytics platforms, and data-driven dApp UIs that would require a traditional database and backend server without The Graph. For Nigerian developers new to Web3 or transitioning from traditional web development, The Graph's GraphQL interface feels familiar — it is semantically similar to querying a REST or GraphQL API, just with blockchain data as the source. This lowers the learning curve significantly compared to raw blockchain interaction, making The Graph one of the most developer-friendly tools in the Web3 ecosystem for Nigerian builders exploring decentralized finance and NFT development. The Graph's subgraph studio enables Nigerian developers to deploy and test subgraphs on the hosted service before publishing to the decentralized network, providing a development environment for iterating on indexing logic before committing to production deployment. This staged deployment model reduces the risk of publishing incomplete or buggy indexing logic to the production network.

91. Rapyd Payout API

Payments, Development Tools, Banking & Fintech

Rapyd is a global Fintech-as-a-Service (FaaS) platform that provides businesses with a single API to collect payments, disburse payouts, and manage financial operations across 100+ countries and 900+ local payment methods. Founded in 2016 and headquartered in Tel Aviv, Israel, Rapyd is backed by Stripe and other major investors, and has a community of 50,000+ developers. The Rapyd API covers the complete payment lifecycle: online checkout, virtual accounts, hosted payment pages, multi-currency wallets, card issuing, FX conversion, and bulk disbursements. The Rapyd API is RESTful with JSON payloads. Documentation is at docs.rapyd.net. Authentication uses HMAC SHA-256 signing — a security scheme where every API request is signed using the access key and secret key provided during onboarding. This is more complex than Bearer Token auth and requires developers to implement the signing algorithm correctly. The signature is computed from the HTTP method, endpoint path, salt, timestamp, access key, and request body, then base64-encoded and included in the request header. Rapyd provides code samples in multiple languages to simplify implementation. Rapyd's core product for global payments is the Collect API, which enables businesses to accept local payment methods in 100+ countries. Rather than integrating with dozens of country-specific payment processors, businesses integrate Rapyd once and get access to payment methods including bank transfers, cash payment networks, direct debit, mobile wallets, and card networks in each country. For Nigeria and Africa, Rapyd's local payment method coverage includes relevant African payment rails — exact Nigerian payment methods available can be queried via the Rapyd Payment Methods API (GET /v1/payment_methods/country?country=NG). The Payout API enables mass disbursements to bank accounts and e-wallets globally. Businesses can send payments to employees, contractors, vendors, and customers in 100+ countries. Rapyd automatically handles FX conversion when the payout currency differs from the source currency. Rapyd also offers multi-currency wallets — virtual accounts that can hold balances in multiple currencies. This is useful for platforms managing funds on behalf of multiple currencies and wanting to minimize FX conversion costs by holding funds in the appropriate currency. Card issuing is another major feature — businesses can use the Rapyd API to issue virtual and physical Visa/Mastercard cards to their users in supported markets. This powers expense management tools, corporate card programs, and employee benefit cards. The Rapyd sandbox environment is fully featured and allows testing of all payment methods, disbursements, and card operations using test credentials. The developer community at community.rapyd.net provides support and knowledge sharing. From a compliance standpoint, Rapyd is an authorized Electronic Money Institution in the UK (FCA), an authorized Payment Institution in the EU (Lituanian FSA), and holds licenses in other jurisdictions. For Africa and Nigeria specifically, Rapyd works with local regulated partners to ensure compliance with CBN requirements. Frequently Asked Questions: Does Rapyd support Nigeria directly? Nigeria is accessible through Rapyd's Africa local payment method network. Use the Payment Methods API with country=NG to see currently available Nigerian payment methods. Why does Rapyd use HMAC SHA-256 instead of Bearer tokens? HMAC signing provides additional security for high-value enterprise transactions — each request is individually signed, preventing replay attacks and request forgery. Can Nigerian businesses sign up for Rapyd directly? Businesses need to have a legal entity in a Rapyd-supported country. Nigerian companies should contact Rapyd to confirm current onboarding eligibility.

92. FastForex

Payments, Trading & Currency Exchange

FastForex is a currency exchange rate API providing current and historical mid-market rates across 150+ world currencies plus common commodities (gold, silver), aimed at applications needing straightforward rate data without the tick-level bid/ask granularity that dedicated trading-focused forex APIs (like 1Forge) provide. A single GET request returns either the latest rates for a base currency against all others, or a direct conversion between two specific currencies with the amount already calculated. The API supports historical rate lookups for a specific past date (useful for financial reporting or reconciling a transaction against the rate at the time it occurred) and time-series data over a date range for building rate-history charts. Response times are optimized to be fast (as the name suggests) since the primary use case is real-time display in checkout flows, invoicing tools, and price converters rather than algorithmic trading. For Nigerian e-commerce platforms displaying prices in multiple currencies, invoicing tools converting NGN amounts for international clients, or expense-tracking apps needing historical exchange rates for reconciliation, FastForex's simple request/response model and generous free tier make it a lower-friction choice than a full trading-grade forex API when bid/ask spread precision isn't required.

93. ChangeNOW API

Blockchain, Payments

ChangeNOW is a non-custodial instant cryptocurrency exchange service that provides an API for embedding crypto-to-crypto swaps directly into wallets, apps, and platforms. Unlike centralized exchanges (Binance, Coinbase) that require user account creation, KYC verification, and custody of funds on the exchange, ChangeNOW operates as a swap service: users provide their source asset and destination wallet address, ChangeNOW executes the exchange across its liquidity network, and the converted asset lands directly in the user's own wallet. The entire swap is non-custodial — ChangeNOW never holds user funds beyond the brief swap execution window. For Nigerian developers building crypto wallets, payment processors, and DeFi applications, ChangeNOW is one of the most practical APIs for providing swap functionality. Nigeria's crypto users frequently need to convert between assets — swapping Bitcoin received from a remittance into USDT for stability, converting accumulated altcoins into BTC for cold storage, or exchanging ETH for BNB to take advantage of lower gas fees. Without a swap API like ChangeNOW, these conversions require users to go to an exchange, which is cumbersome and, for some Nigerian users, inaccessible due to exchange restrictions. The exchange rate estimation endpoint (/exchange/estimated-amount) is the starting point for any swap flow. Given a source currency (e.g., BTC), destination currency (e.g., USDT), and amount, it returns the estimated output amount, the exchange rate, and the estimated completion time. This allows Nigerian applications to show users the exact expected output before they initiate the swap — building trust and transparency in the exchange process. ChangeNOW supports both floating rate and fixed rate exchanges. With floating rates, the final output amount may differ slightly from the estimate due to market movements during the brief swap window — the user gets the market rate at execution time. With fixed rates, ChangeNOW locks in the exchange rate for a short window (typically 30-120 seconds) during which the user must send the source asset — the output is guaranteed at the quoted amount. Fixed rates are more user-friendly for Nigerian users who want certainty about what they will receive. Creating an exchange (/exchange) generates a unique deposit address where the user must send the source asset. The API returns this address, the expected output amount, and an exchange ID for tracking. Once ChangeNOW detects the incoming funds, it executes the swap and sends the converted asset to the user's destination address. The entire process typically completes in 2-15 minutes depending on the blockchain confirmation requirements for the source asset. Transaction status tracking via the /exchange/by-id endpoint allows applications to display real-time swap progress to Nigerian users: waiting for deposit, confirming source blockchain, exchanging, sending to destination, and completed. This status feed is important for user experience — crypto swaps are not instant, and users need reassurance that their funds are being processed correctly. Coverage of 850+ trading pairs means Nigerian users can swap virtually any commonly held cryptocurrency. The coverage includes Bitcoin (BTC), Ethereum (ETH), USDT (on Tron, Ethereum, and BNB Chain), BNB, Solana (SOL), XRP, Dogecoin, and hundreds of altcoins. Minimum amounts vary by pair based on liquidity conditions and blockchain fees; the API provides a minimum amount endpoint so applications can validate user input before attempting a swap. The API is completely free — ChangeNOW earns revenue from the spread between exchange rates, so there are no subscription fees or per-call charges for API usage. A free API key is obtained from changenow.io/api with no credit card required, and no geo-blocking for Nigerian developers has been reported.

94. Mono Connect

Payments

Mono is a Nigerian open banking and financial data infrastructure company that enables developers to build financial products by connecting customer bank accounts for data access, payments, and identity verification. Founded in 2020 by Abdul Hassan and Prakhar Sharma, Mono has raised funding from Sequoia Capital India and other top investors, and is one of Africa's leading open banking providers, covering over 30 Nigerian banks and financial institutions. The Mono platform is organized into three main API products: Financial Data, Payments (DirectPay), and Identity Verification. All three use the same developer credentials and are accessed via the Mono Connect widget — an embeddable authentication flow that allows customers to authorize Mono's access to their bank account using their internet banking credentials, in accordance with CBN open banking guidelines. The Financial Data API provides programmatic access to a bank account's transaction history, current balance, income patterns, and bank statements after the customer authorizes access through the Connect widget. Lenders use this data for credit scoring — analyzing spending patterns, income credits, and debt obligations from actual bank statements rather than relying on self-reported income. The transactions endpoint returns categorized transaction records covering 12–24 months of history depending on the bank. The Payments API, branded as DirectPay, enables businesses to initiate single direct debits from a linked customer bank account — charging the account directly without requiring the customer to enter card details. DirectPay is powered by open banking standards, with all transactions encrypted end-to-end. Pricing is 1% per successful transaction, capped at NGN 1,000. This makes DirectPay significantly cheaper than card payment fees (Paystack charges 1.5% + ₦100 capped at ₦2,000) for high-value transactions — for example, a ₦500,000 loan repayment via DirectPay costs ₦1,000 (capped), versus ₦2,100 via card. Mono also offers a Recurring Direct Debit product — where a customer authorizes ongoing debits on a schedule — enabling subscription billing, loan installment plans, and salary deductions using open banking mandates rather than card tokens. Authentication is handled via the Client Secret Key, which is included in request headers as mono-sec-key. Public keys are used client-side to initialize the Connect widget. Mono provides SDKs for React, React Native, JavaScript, Android, and iOS — all of which embed the Connect widget and handle the token exchange flow. Most integrations take 2–4 hours. For identity verification, Mono offers BVN verification, NIN verification, and document verification (government-issued ID). These are standalone API calls that do not require bank account linking — useful for KYC onboarding where the business needs to verify user identity before granting access to financial services. Mono's Identity API also supports address verification and company verification via CAC data — enabling Know Your Business (KYB) checks for B2B platforms and marketplace operators. The sandbox environment is available at mono.co/sandbox with test bank credentials provided in the documentation. All three products (Financial Data, DirectPay, Identity Verification) are testable in sandbox mode before going live. From a compliance standpoint, Mono operates under the CBN's Regulatory Framework for Open Banking in Nigeria. All data access is customer-authorized and consent-revocable. Mono is registered with the Nigerian Data Protection Regulation (NDPR) as a data controller and processor. The Connect widget displays clearly what data a business is requesting before the customer approves access. Mono covers over 30 Nigerian financial institutions including GTBank, First Bank, Zenith Bank, Access Bank, UBA, Sterling Bank, Kuda, OPay, PalmPay, and most major microfinance banks. Frequently Asked Questions: Can I access a customer's bank account without their permission? No — the Mono Connect widget requires explicit customer authorization. The customer sees exactly what data the platform is requesting and must provide their internet banking credentials to approve access. How long does bank account access last? Customer authorizations can expire or be revoked. Mono's refresh token mechanism allows businesses to refresh data access periodically, but customers can revoke access at any time via the Mono Customer Portal. Does DirectPay work for all Nigerian banks? DirectPay covers 30+ institutions but not all banks. Coverage continues to expand as Mono adds new integrations. Can I use Mono for business account verification? Yes — Mono's Identity API includes CAC verification for business account checks, in addition to individual BVN/NIN verification.

95. RexPay (Global Accelerex)

Payments

RexPay is a Nigerian payment gateway solution developed by Global Accelerex Limited, a leading electronic payment and business management solutions company operating in Nigeria and West Africa. Global Accelerex holds both a CBN Payment Solution Service Provider (PSSP) certification and a CBN Payment Terminal Service Provider (PTSP) certification — a dual certification that covers online payment processing and POS terminal management respectively. This makes Global Accelerex one of the few Nigerian companies with both licenses, giving RexPay institutional-grade credibility as a payment infrastructure partner. The RexPay API is RESTful with JSON payloads. Documentation is available at rexpay-docs.globalaccelerex.com. Authentication uses an API Key obtained from the RexPay merchant dashboard. Developers initialize payment transactions by sending a POST request with the amount and transaction reference, then display the RexPay checkout to the customer. RexPay supports three payment channels in Nigeria: card payments (Visa, Mastercard, Verve with 3D Secure / 2FA verification), internet banking transfers (bank-to-bank transfers via the customer's internet banking), and USSD (for customers on basic mobile phones without internet access). This covers the three primary payment behaviors of Nigerian consumers: card users, mobile banking users, and USSD users. For WordPress-based e-commerce stores, RexPay provides a WooCommerce plugin that can be installed directly from the WordPress plugin directory. This no-code integration allows Nigerian merchants to add RexPay checkout without writing a single line of code — simply install, configure the API key from the dashboard, and payments start flowing. Pricing for RexPay starts from $0 per month, indicating no mandatory platform fee. Transaction fees are commission-based and negotiated during merchant onboarding. The exact percentage rates are not published publicly but are competitive with other Nigerian gateways. The $0/month model makes RexPay accessible to small businesses and startups that cannot commit to monthly subscription fees. The sandbox environment allows full testing of all payment channels. Moving to live requires completing the Global Accelerex KYC process, which involves submitting CAC documents, director BVN, and business bank account information. From a compliance standpoint, Global Accelerex is CBN-certified under both the PSSP and PTSP frameworks, meaning that all payment transactions processed through RexPay meet CBN regulatory standards. PCI-DSS compliance ensures card data is handled and stored securely. RexPay is a focused Nigeria-only payment gateway — it does not currently support international payment corridors or other African countries. This is a trade-off that simplifies compliance but limits its usefulness for businesses with pan-African payment needs. Known challenges: RexPay's documentation and developer community are smaller than Paystack or Flutterwave. Advanced features like split payments, virtual accounts, and recurring billing are not currently supported. International card acceptance (for non-Nigerian Visa/Mastercard holders) may have limitations. Frequently Asked Questions: What is Global Accelerex? Global Accelerex is the parent company of RexPay. It is one of Nigeria's oldest e-payment companies, providing POS terminals, payment switches, and software solutions to Nigerian banks and enterprises since the early 2000s. Does RexPay work with WooCommerce? Yes — a WooCommerce plugin is available that allows Nigerian WordPress store owners to accept payments through RexPay without any coding. Can I use RexPay for B2B corporate payments? Yes — RexPay supports internet banking transfers, which is the preferred payment method for Nigerian corporate clients making large business-to-business payments.

96. QuickNode

Development Tools, Blockchain

QuickNode is a managed blockchain infrastructure platform providing fast, reliable RPC node access for over 35 blockchains through a single developer account and unified management dashboard. Founded in 2017 and headquartered in Miami, QuickNode serves thousands of developers and enterprises globally, powering Web3 applications across DeFi, NFTs, gaming, payments, and infrastructure. For Nigerian blockchain developers, QuickNode is a strong alternative to Alchemy, particularly valued for its breadth of chain support, the add-on marketplace that extends functionality beyond basic RPC, and competitive pricing on paid plans. The 35+ blockchain coverage is one of QuickNode's key differentiators. Beyond the major EVM chains (Ethereum, Polygon, Arbitrum, Optimism, Base, BNB Smart Chain), QuickNode supports non-EVM chains including Solana, Avalanche, Near, Fantom, Tron, XRPL, Stellar, Celo, Harmony, and Bitcoin (full node and Electrum). For Nigerian developers building multi-chain applications or exploring newer blockchain ecosystems, having access to all these chains from a single provider simplifies infrastructure management significantly. The add-on marketplace is a distinctive QuickNode feature that extends basic RPC functionality with specialized data services. Add-ons can be enabled per endpoint from the dashboard, including: NFT Fetch for NFT metadata and ownership data, Token and Address Analytics for wallet portfolio tracking, DeFi price feeds, Solana priority fee recommendations, transaction simulation, and more. These add-ons are billed as extensions to the base node plan, allowing Nigerian developers to enable exactly the functionality they need without paying for unused features. QuickAlerts is QuickNode's webhook notification system for blockchain events. Developers configure alerts based on transaction patterns — address activity, smart contract event emissions, NFT transfers, token transfers — and QuickNode delivers webhooks when matching activity occurs on-chain. For Nigerian crypto applications tracking user deposits, DeFi protocol event monitoring, or blockchain payment confirmation, QuickAlerts eliminates polling and enables real-time application responses to blockchain events. WebSocket endpoints allow maintaining persistent connections for real-time blockchain data subscriptions — new block headers, pending transactions in the mempool, event log subscriptions, and account state changes. WebSocket subscriptions are essential for Nigerian applications that display live blockchain data (current gas prices, live transaction feeds, real-time price updates from on-chain oracles) to users. The dashboard analytics provide visibility into endpoint usage — request volume, methods called, error rates, latency histograms — helping Nigerian developers monitor their application's blockchain infrastructure consumption and optimize usage to stay within plan limits. Low-latency global endpoints with geographically distributed node infrastructure ensure that Nigerian developers and their users get responsive blockchain data. QuickNode's edge network routes requests to the nearest available nodes, reducing round-trip latency for blockchain queries originating from Nigerian applications. Pricing starts with a free plan (one endpoint per chain, rate-limited) and scales through paid plans starting at $9/month for higher request throughput and multiple endpoints. Nigerian developers building production applications with significant user volume typically require paid plans to ensure adequate request capacity. Enterprise plans with dedicated infrastructure are available for high-volume deployments. QuickNode is particularly well-suited for Nigerian Web3 developers who need access to multiple chains simultaneously, value the add-on marketplace for data enrichment, or are building non-EVM chain applications (particularly Solana) where QuickNode has strong node infrastructure and tooling.

97. NowNow API

Payments, Development Tools

Digital payments API for quick and easy money transfers. NowNow provides APIs for person-to-person transfers, bill payments, and merchant payments. Designed for fast, accessible payment processing across Africa.

98. Epic Pay

Development Tools, Payments

Epic Pay (Epic Payment Technologies Limited) is a Nigerian PSS-licensed payment gateway offering a full suite of developer APIs through a dedicated developer portal at developer.epicpay.com. The platform is PCI DSS 4.0 certified — one of the most current versions of the payment security standard — and provides Payment, Boarding/Agent, and Reporting APIs alongside SDKs for Java and C#/.NET. Epic Pay is notable for its white-label capabilities and its active developer community, the Epic Pay Developers Circle. What the API Does The Epic Pay API suite covers three main areas: (1) Payment API — initiate one-time and recurring payments, tokenize card payloads, manage customer records, and perform Address Verification Service (AVS) checks. (2) Boarding/Agent API — programmatically onboard merchants and agents onto the Epic Pay gateway, configure their settings, and manage their accounts. (3) Reporting API — retrieve real-time and historical transaction data for reconciliation and financial reporting. How Developers Use It Developers access the portal at developer.epicpay.com, create an account, obtain API keys, and integrate using the provided documentation and SDKs. Java and C#/.NET SDKs are available to simplify integration. The API is REST-based. A Dev Lab environment is available for sandbox testing.

Authentication API Key from the EpicPay Gateway Developer Portal. Keys are used to authenticate all API requests. Compliance PSS (Payment Service Solution) licensed by the CBN. PCI DSS 4.0 certified — one of the most current PCI versions, demonstrating strong card data security practices. Challenges and Gotchas (1) No USSD or crypto support. (2) Pricing not public — requires direct engagement. (3) Less community presence than Paystack/Flutterwave — documentation depth may be lower. (4) White-label and agent boarding make it more suitable for ISOs and platform builders than simple merchant integrations. Company Background Epic Payment Technologies Limited is a Nigerian payment company focused on providing payment infrastructure for businesses, developers, and agent networks. The Developers Circle community initiative shows active engagement with the Nigerian developer ecosystem. FAQs Q: Does Epic Pay support recurring billing? A: Yes. The Payment API supports recurring payments with tokenized card storage. Q: Is there a sandbox? A: Yes. A Dev Lab environment is available at developer.epicpay.com/Docs/DevLab. Q: What SDKs are available? A: Java and C#/.NET SDKs are available on GitHub under EpicGateway organization. Q: Can I build a white-label payment product with Epic Pay? A: Yes. Epic Pay specifically supports white-label payment platform deployments with the Boarding API for sub-merchant management. PCI DSS 4.0 certification at Epic Pay ensures that the platform meets the most current version of the Payment Card Industry Data Security Standard, providing Nigerian merchants with confidence that card data processed through Epic Pay is handled in compliance with international card scheme security requirements. For Nigerian businesses that accept card payments through Epic Pay's infrastructure, the certification removes independent PCI compliance burden from the merchant's own systems for card data that flows through Epic Pay's hosted solutions. The white-label capability of Epic Pay allows Nigerian fintech companies to deploy a branded payment gateway under their own product identity, using Epic Pay's underlying infrastructure and licensing without exposing the white-label arrangement to end customers. This model benefits Nigerian fintechs that want to offer payment collection as part of a broader product suite — a lending platform offering collection infrastructure to borrowers, an HR platform providing payroll collection tools — under their own brand without building and licensing payment infrastructure independently. Agent boarding through Epic Pay's multi-API developer portal enables platforms managing agent networks to programmatically register agents, configure their access levels, and provision their payment acceptance capabilities. For Nigerian platforms operating agent banking networks, field sales agent networks, or merchant partner programs, automated agent onboarding through an API dramatically reduces the operational cost and time of expanding the agent network compared to manual registration processes.

99. NOWNodes

Blockchain, Development Tools

NOWNodes is a blockchain-as-a-service provider offering full node access to over 50 blockchains through a unified API key. Founded in 2019, NOWNodes distinguishes itself by covering both UTXO-based chains (Bitcoin, Litecoin, Bitcoin Cash, Dash, Dogecoin, Zcash) and EVM-compatible chains in one platform — making it particularly useful for developers building applications that need Bitcoin alongside Ethereum rather than just EVM chains. For Nigerian developers building crypto wallets, exchanges, or payment applications that must handle Bitcoin transactions, NOWNodes provides a straightforward path to Bitcoin RPC access. The UTXO chain support is where NOWNodes stands out from primarily EVM-focused providers like Alchemy or Moralis. Bitcoin and similar UTXO chains use a fundamentally different data model from Ethereum — transactions consume unspent outputs rather than updating account balances. Building Bitcoin integrations requires UTXO management, raw transaction construction, and Bitcoin-specific RPC methods that EVM node providers do not offer. NOWNodes Bitcoin node access provides the full Bitcoin Core RPC interface including getutxos, getrawtransaction, sendrawtransaction, and all other methods needed for robust Bitcoin integration. The blockchain explorer API extends beyond raw RPC to provide indexed blockchain data — address balances, transaction histories, and block data in a query-friendly format that is faster and more convenient than parsing raw RPC responses. For Nigerian exchange or wallet applications needing to display transaction history and current balances for user addresses, the explorer API endpoints provide this data in a clean format without custom indexing. 50+ chain coverage includes Bitcoin (BTC), Ethereum (ETH), BNB Smart Chain, Polygon, Solana, Avalanche, Tron, Litecoin (LTC), Dogecoin (DOGE), Bitcoin Cash (BCH), XRP, and many others. This breadth supports Nigerian crypto applications that need to handle a wide range of cryptocurrencies for their users. The free plan (60,000 requests per day) is less generous than Ankr or dRPC but sufficient for development and low-traffic production. Paid plans starting at $20/month offer higher daily request limits. Dedicated node options provide isolated infrastructure for high-volume production deployments. NOWNodes supports both shared node endpoints (ideal for development and moderate production loads) and dedicated nodes (for applications requiring guaranteed throughput and isolation from other users' traffic). Dedicated nodes eliminate the shared resource contention that can cause response time variability at peak usage periods. The platform's chain coverage spans major proof-of-work, proof-of-stake, and other consensus mechanism chains — enabling Nigerian developers to interact with Bitcoin's UTXO model, Ethereum's account model, and other blockchain architectures through a unified API key and billing relationship. For Nigerian crypto applications and Web3 projects, having reliable node access is the difference between a functioning product and an unreliable one. User-facing applications that depend on blockchain connectivity for wallet balances, transaction broadcasts, and smart contract calls require the kind of managed reliability that NOWNodes provides — handling node maintenance, version upgrades, and infrastructure failures transparently. Block explorer APIs complement the basic node access, providing higher-level queries for address transaction history and balance lookups that would otherwise require parsing raw blockchain data — saving significant development time for Nigerian developers building wallet and portfolio tracking features.

100. Nomba API

Payments, Development Tools

Nomba is a Nigerian payment infrastructure company and CBN-licensed Payment Service Provider. Formerly known as Kudi, Nomba pivoted from a consumer-facing payment agent app to a comprehensive B2B payments infrastructure platform serving Nigerian businesses with APIs for checkout, virtual accounts, transfers, and POS terminal management. Nomba is backed by Stripe and significant venture capital, and powers millions of transactions daily across Nigeria's merchant and agent banking ecosystem. The Nomba API is RESTful with JSON payloads and uses OAuth2 for authentication. Developers can authenticate via two methods: the Client Credentials grant (server-to-server, for backend integrations) or the PKCE (Proof Key for Code Exchange) grant (for mobile and single-page app integrations where the secret cannot be safely stored). In both cases, an access_token is generated and passed in every API request as an Authorization: Bearer <token> header. API keys are retrieved from the Nomba business dashboard under Settings > API Keys. The Checkout API is the core product for accepting payments. Developers initialize a checkout session server-side by sending a POST request with the amount, currency (NGN), and a unique transaction reference. Nomba returns a hosted checkout URL that the developer redirects the customer to. The checkout supports card payments (Verve, Visa, Mastercard), USSD, and bank transfers. Nomba handles the entire payment experience on its hosted page — merchants do not need to build a custom checkout interface. For fund collection from specific customers, Nomba supports Virtual Accounts — unique bank account numbers assigned to individual customers or transactions. When a customer transfers any amount to their virtual account number, Nomba fires a webhook confirming the payment. This is ideal for Nigerian wallet top-ups, marketplace deposits, and savings apps where customers fund their balance via bank transfer. The Transfers API enables instant outbound bank transfers to any Nigerian bank account. Developers can send disbursements by specifying the destination bank code, account number, amount, and a unique transfer reference. Nomba executes the transfer via the Nigerian banking system. This is commonly used for payroll, agent commissions, loan disbursements, and refunds. Nomba also supports tokenized card flows — when a customer first pays with a card, Nomba can return a card authorization token that the merchant stores and uses for future charges without requiring the customer to re-enter card details. This enables installment plans, subscription-like products, and one-click repeat payments. For merchants with physical locations, Nomba provides a Terminals API that enables developers to build custom POS applications. Integrators can send payment requests to Nomba POS terminals, receive confirmation webhooks, and build merchant dashboards that pull transaction data from the terminal network. This is a unique capability that distinguishes Nomba from pure online payment gateways like Paystack or Flutterwave. Webhooks are available for all major events: payment success, payment failure, transfer completion, and virtual account credit. Developers must validate the webhook signature before processing events to ensure authenticity. The Nomba sandbox environment is available for all API products. Developers can test checkout, virtual accounts, and transfers without processing real money. Moving to live requires completing Nomba's business onboarding and CBN KYC verification. From a compliance standpoint, Nomba holds a CBN Payment Service Bank license and is licensed as a Payment Service Provider. All transactions are processed within the CBN regulatory framework. The platform is used by hundreds of thousands of Nigerian merchants, particularly small businesses, market traders, and logistics companies that use Nomba POS terminals. Frequently Asked Questions: How is Nomba different from Paystack? Paystack is primarily an online payment gateway. Nomba additionally offers POS terminal integration, agent banking infrastructure, and the Global Payout API for cross-border disbursements — making it more comprehensive for merchants with physical and digital presence. Is Nomba pricing public? Nomba does not publish exact API pricing. Contact the Nomba team for transaction fee schedules based on your volume and use case. Can I use Nomba for cross-border payments? The main Nomba API is for domestic Nigerian payments. For cross-border disbursements, use the separate Nomba Global Payout API which was launched in March 2026.

101. Busha Commerce API

Payments, Development Tools

Busha Commerce API is the developer platform for Busha, Nigeria's leading regulated cryptocurrency exchange founded in 2019. While global exchanges like Binance and Coinbase face regulatory friction and account restrictions in Nigeria, Busha operates as a Nigerian-registered entity, holds all required local licences, and is fully compliant with Nigerian financial regulations. This makes Busha the most trusted and legally reliable option for Nigerian businesses that want to accept cryptocurrency payments, provide crypto trading services, or build crypto-powered products for Nigerian users. The Busha Commerce API specifically targets Nigerian merchants and developers who need crypto payment acceptance with Nigerian Naira settlement. Nigeria's digital economy is growing rapidly, but Nigerian businesses face persistent challenges with conventional payment infrastructure: card declines on international transactions, Forex restrictions limiting dollar-denominated purchases, and high remittance fees. Cryptocurrency — particularly USDT (a stablecoin pegged to the US dollar) — has emerged as a practical alternative for Nigerians making and receiving international payments. Busha Commerce bridges the gap between crypto payments and the Nigerian Naira banking system, enabling merchants to accept crypto from customers anywhere in the world and receive NGN in their bank accounts. The payment workflow is straightforward. A Nigerian merchant creates a payment request via the API, specifying the amount in NGN or a crypto asset. Busha returns a payment address (or QR code) and a unique payment ID. The merchant displays this to the customer. When the customer sends crypto to that address, Busha detects the blockchain transaction, converts it to NGN at the current exchange rate (if NGN settlement is selected), and delivers a webhook notification to the merchant's server confirming the payment. The merchant can then fulfill the order knowing the NGN equivalent has been credited to their Busha balance. Exchange rate endpoints provide real-time NGN/BTC, NGN/ETH, and NGN/USDT rates based on Busha's live market rates. These rates reflect the actual rates at which Busha will settle payments — not third-party price data — ensuring Nigerian merchants display accurate expected payment amounts to their customers. The rates include Busha's exchange margin, so what the merchant sees is what they will receive. Webhook notifications are the backbone of the payment detection system. When a payment is received and confirmed on-chain, Busha sends an HTTP POST to the merchant's configured webhook URL with full payment details: amount paid, asset type, exchange rate applied, NGN value, and transaction status. The webhook payload is signed with a secret key so merchants can verify it genuinely came from Busha. This event-driven architecture means Nigerian merchant backends respond immediately to payments without polling. For Nigerian freelancers and service providers, Busha Commerce enables a particularly useful workflow: generate a shareable payment link for a specific invoice amount, send it to an international client, receive USDT payment from anywhere in the world, and settle to NGN via Busha's banking integration. This circumvents the delays and fees of international wire transfers and the restrictions that Nigerian bank accounts sometimes face on receiving foreign currency. The sandbox environment allows Nigerian developers to test the complete payment flow — creating test payment requests, simulating test payments, and receiving test webhook events — without using real cryptocurrency. This makes integration development safe and fast. Busha requires business KYC verification including CAC (Corporate Affairs Commission) registration documents for merchant accounts — consistent with Nigerian financial compliance requirements. API keys are generated after verification in the Busha developer dashboard.

102. Raenest API

Payments

Cross-border payment API for African diaspora remittances and international transfers. Raenest enables developers to integrate cross-border payment capabilities for sending money from anywhere to Africa with competitive rates and fast settlement.

103. OnFinality

Development Tools, Blockchain

OnFinality is a blockchain infrastructure and node-as-a-service platform specializing in Polkadot, Kusama, and Substrate-based blockchain networks, as well as a growing catalog of EVM-compatible chains. It provides developers with reliable, globally distributed RPC node endpoints and advanced APIs that enable interaction with these blockchain networks without the cost and complexity of running and maintaining nodes independently. The Polkadot and Substrate ecosystem is one of the most technically sophisticated in Web3, with a multi-chain architecture where Polkadot serves as a relay chain connecting many specialized parachains. Building on this ecosystem requires reliable access to node infrastructure for each chain — submitting transactions, querying chain state, reading events, and subscribing to block updates. OnFinality provides these endpoints for Polkadot, Kusama, and dozens of Substrate-based parachains (Acala, Moonbeam, Astar, Phala, and many others) through a unified platform. The API endpoints support both HTTPS (for request-response RPC calls) and WebSocket (for subscriptions and persistent connections). WebSocket connections are essential for applications that need to subscribe to real-time blockchain events — new blocks, transaction confirmations, and state changes — without polling. This is particularly important for DApps that display live blockchain data to users. Beyond basic node access, OnFinality provides Enhanced APIs that offer higher-level, more developer-friendly query capabilities over raw RPC. These enhanced endpoints simplify complex data retrieval tasks that would otherwise require multiple RPC calls and custom parsing logic. SubQuery indexer hosting is also available — allowing developers to deploy SubQuery indexing projects that transform raw blockchain data into a structured GraphQL API, which is the standard pattern for building data-rich DApps on Substrate. For Nigerian blockchain developers and Web3 startups working in the Polkadot ecosystem, OnFinality provides the infrastructure layer that makes building feasible. Running Substrate nodes requires significant server resources, technical expertise, and ongoing maintenance. OnFinality abstracts this entirely, letting Nigerian developers focus on application logic and user experience rather than node operations. Nigerian Web3 projects building in the Polkadot ecosystem — DeFi protocols, NFT platforms, cross-chain bridges, and governance tools — can use OnFinality to access all the chains they need through a single provider and API key, simplifying their infrastructure stack and reducing operational overhead. The free tier provides 500,000 API calls per day, which is sufficient for active development, testing, and early production deployments. Paid tiers scale to tens of millions of calls per day for production DApps with significant user bases. Pricing is predictable and billed monthly, making budget planning straightforward for Nigerian startup teams. OnFinality's SubQuery indexer hosting service is a significant value-add beyond basic node access. SubQuery is the leading data indexing framework for Substrate and Polkadot chains, enabling developers to define custom indexing logic and deploy it as a managed GraphQL API. Nigerian Web3 teams building data-heavy applications — portfolio trackers, DEX analytics, governance dashboards — can deploy their SubQuery projects on OnFinality's infrastructure rather than managing indexer servers independently. The OnFinality monitoring dashboard provides visibility into API usage, request rates, error rates, and latency metrics across all endpoints. Nigerian development teams can monitor their blockchain API consumption to stay within plan limits, identify performance bottlenecks, and diagnose connectivity issues from a single operations console. OnFinality's developer support covers Substrate and Polkadot-specific questions that general cloud support teams cannot answer — providing ecosystem-specific expertise that reduces debugging time for Nigerian developers who are newer to the Polkadot ecosystem.

104. Allawee Card Issuance API

Payments, Banking & Fintech

Allawee Card Issuance API is a Nigerian Banking-as-a-Service platform that enables fintech companies, microfinance institutions, and digital platforms to issue physical and virtual payment cards, create bank accounts, process transfers, and perform credit decisioning through a single API integration. Allawee provides the regulated infrastructure for card issuance and banking operations, allowing partner platforms to offer branded financial products without obtaining independent banking or card scheme licenses. Card issuance is the foundational capability of the Allawee platform. Partner applications can issue Mastercard or Verve physical cards linked to customer accounts through the API, enabling customers of the partner platform to receive a physical payment card they can use at POS terminals, ATMs, and online merchants across Nigeria and globally where the card scheme is accepted. Physical card issuance involves card personalization (embossing customer name and card details), printing, and delivery to customer addresses, all manageable through API calls that initiate the card production and fulfillment workflow. Bank account creation through Allawee enables partner platforms to create functional Nigerian bank accounts for their customers, complete with a NUBAN (Nigerian Uniform Bank Account Number) that is compatible with all Nigerian interbank transfer systems including NIP (NIBSS Instant Payment). Customer accounts created through Allawee can receive inbound transfers from any Nigerian bank and initiate outbound transfers to any Nigerian bank account, providing full interbank connectivity through a single BaaS API integration. Spend controls in the Allawee Card API allow partner platforms to set per-transaction limits, daily spending limits, merchant category restrictions, and geographic restrictions on issued cards. A Nigerian fintech issuing employee expense cards can configure spending controls that prevent cards from being used at non-approved merchant categories. An agricultural platform issuing input finance cards can restrict spending to agricultural input supplier merchant categories, ensuring that financed funds are used for their intended purpose. Credit data decisioning from Allawee leverages transaction history and behavioral patterns on the platform to generate credit scores and lending signals that partner platforms can use for automated loan underwriting decisions. For Nigerian lending platforms that issue cards to their borrowers and want to build repayment history and credit profile data from card usage patterns, Allawee's credit decisioning API provides structured credit signals from the same ecosystem where the lending relationship operates. Tokenization support in the Allawee platform enables issued cards to be added to digital wallets (Apple Pay, Google Pay) by card holders, extending card usability to contactless mobile payments in addition to physical card and online payments. As contactless payment adoption grows among Nigerian consumers particularly in Lagos and other major cities, tokenization support adds a distribution channel for issued cards that increases their day-to-day utility. Dispute management through the Allawee API provides structured workflows for handling card transaction disputes — unauthorized transactions, merchant disputes, technical failures — that partner platforms can initiate programmatically when customers report problems. Automated dispute initiation reduces the manual operational burden of handling customer complaints about card transactions and provides systematic tracking of dispute status and resolution. The CBN regulatory compliance infrastructure behind Allawee means that partner platforms are leveraging a regulated entity's banking and card scheme relationships rather than needing to independently establish CBN licensing, Mastercard or Verve principal membership, and the capital requirements those entail. This significantly lowers the barrier for Nigerian fintechs to add card and banking features to their products, compressing the typical 12-24 month timeline for independent licensing into an API integration that can be completed in days or weeks.

105. Etherscan

Blockchain, Development Tools

Etherscan is the most widely used Ethereum block explorer, and its API is the definitive gateway for querying on-chain Ethereum data without running a full Ethereum node. The Etherscan API provides access to transaction histories, smart contract source code and ABIs, token transfer events, gas price data, block information, and event logs across Ethereum mainnet and all major testnets. For Nigerian Web3 developers, DeFi builders, NFT creators, and crypto businesses operating on Ethereum or EVM-compatible chains, Etherscan is the essential blockchain data layer. Nigeria's crypto ecosystem has seen explosive growth, with millions of Nigerians using Ethereum-based assets — particularly USDT (ERC-20), DAI, and USDC — as a hedge against naira depreciation and as a medium for international payments. Nigerian developers building applications that interact with these assets need to query Ethereum state: Who sent what to whom? Was this transaction confirmed? What is my token balance? What events did this smart contract emit? Etherscan's API answers all of these questions reliably, with a free tier accessible to any developer. The Account module provides the most frequently used endpoints. GET /api?module=account&action=txlist&address={address} returns the full transaction history for any Ethereum address — every inbound and outbound transaction with timestamps, values, gas used, and status. This is the data behind any "Transaction History" feature in a wallet or DeFi dashboard. The tokentx endpoint returns all ERC-20 token transfers involving an address, and the tokennfttx endpoint returns ERC-721 (NFT) transfers. Nigerian crypto businesses that accept USDT payments can monitor inbound transfers programmatically using these endpoints. The Contract module retrieves verified smart contract ABIs via getabi and source code via getsourcecode. Etherscan serves as a global repository of verified Ethereum smart contracts — when a developer deploys a contract and verifies it on Etherscan, the source code and ABI become permanently accessible via the API. Nigerian developers can fetch contract ABIs dynamically rather than bundling them in their frontend code, simplifying development and ensuring they always have the latest ABI. The Gas Tracker (gasoracle endpoint) returns current safe, standard, and fast gas prices in Gwei, along with base fee and estimated confirmation times. This is critical for Nigerian DeFi applications that help users estimate transaction costs before confirming — avoiding situations where users pay unexpectedly high gas fees. Logs module queries allow searching for contract events (Ethereum logs) by address and topic, enabling Nigerian developers to build event-driven applications that react to smart contract activity: NFT mints, DEX swaps, DAO votes, protocol liquidations, and more. The ability to query historical event logs without an indexing service like The Graph makes Etherscan a simpler starting point for many applications. Statistics endpoints return network-wide metrics: total Ether supply, daily transaction counts, average block time, and price data. Token endpoints return information about ERC-20 tokens: total supply, holder count, and price data for tokens with market data. The free API key (obtained at etherscan.io/apis) supports 5 requests per second and 100,000 requests per day — more than sufficient for a Nigerian crypto startup in early stages. Paid plans at $199/month (Standard) and $399/month (Advanced) unlock higher rate limits. Etherscan also provides equivalent APIs for other EVM chains through its family of block explorers: BscScan (for BSC/BNB Chain), PolygonScan, Arbiscan, and Optimistic Etherscan — each with separate API keys but identical endpoint structures.

106. CoinAPI

Blockchain

Institutional-grade cryptocurrency market data API with normalized data from multiple exchanges. Includes OHLCV, depth data, and comprehensive historical coverage. Trusted by enterprises.

107. Miden Banking as a Service API

Payments

Miden Banking as a Service API is a sub-Saharan African fintech infrastructure platform that provides card issuance, corporate expense management, virtual accounts, wallet-as-a-service, and multi-country payout capabilities to financial institutions, fintechs, enterprises, and technology companies building embedded payment and financial products across Africa. Miden focuses on the corporate and enterprise financial product space, with particular strength in expense management, corporate card programs, and cross-border payment disbursement. Corporate card issuance is a key Miden capability, enabling partner organizations to issue company expense cards to employees with programmatic spend controls, real-time transaction visibility, and expense categorization. Miden's corporate card infrastructure supports building employee expense management tools where finance teams can see every card transaction in real time, configure per-employee or per-category spending limits, and reconcile expenses automatically without waiting for end-of-month manual reconciliation. For Nigerian companies managing employee expenses across multiple locations and departments, programmatic corporate card management replaces unwieldy petty cash and reimbursement processes. Virtual card issuance through Miden enables platforms to create virtual cards for specific use cases: vendor payment cards with merchant restrictions, single-use purchase cards for procurement, corporate virtual cards for online business expenses, and customer-facing virtual cards for fintech products. Virtual cards are created instantly through the API without physical card production timelines, making them suitable for immediate digital payment needs. NGN and USD accounts provide multi-currency financial infrastructure for Miden partner platforms. Naira accounts enable Nigerian interbank transfers and local payment operations. USD accounts allow platforms to hold dollar balances, make USD-denominated payments, and provide foreign currency account functionality to their customers. The combination of naira and dollar accounts in a single integration supports the multi-currency operational needs of Nigerian businesses engaged in both local and international commerce. Bill payments integration through Miden enables partner platforms to offer airtime top-up, utility bill payment (AEDC, EKEDC, IKEDC, BEDC), cable TV subscriptions (DSTV, GOtv, Startimes), internet data subscriptions, and other Nigerian bill payment categories to their customers. Embedding bill payments into a fintech or banking product increases platform stickiness — customers who pay all their bills through the same app they use for banking are less likely to churn to competing products. Bulk payout operations through Miden enable mass disbursement to bank accounts and mobile money wallets across multiple African countries. For Nigerian logistics companies, gig economy platforms, agricultural aggregators, and marketplace operators that need to pay large numbers of individuals across Nigeria and neighboring markets, Miden's bulk payout API provides the disbursement infrastructure to process hundreds or thousands of individual payouts efficiently in a single operation. Wallet as a Service capabilities allow partner platforms to create digital wallets for their customers — stored value accounts that can receive deposits, make payments, and earn rewards — without the complexity of building wallet infrastructure independently. For Nigerian platforms wanting to add a loyalty or savings wallet feature to their product suite, Miden's Wallet as a Service provides the backend for wallet account management, balance tracking, and transaction processing. Mobile money payout support extends Miden's disbursement coverage to mobile money wallet recipients in markets where mobile money is the primary financial access tool — particularly relevant for cross-border payouts to recipients in Ghana (MTN Mobile Money, Vodafone Cash), Kenya (M-Pesa), and other African markets where mobile money is more prevalent than bank accounts. This multi-rail payout coverage enables Nigerian platforms reaching pan-African beneficiary populations to make payouts regardless of whether recipients have bank accounts.

108. AZA Finance API

Development Tools, Payments

AZA Finance is a pan-African payments and foreign exchange infrastructure company that enables businesses and fintechs to send, receive, and convert money across Africa and globally through a single API. Originally founded as BitPesa in Nairobi in 2013, AZA Finance has evolved into one of Africa's most established cross-border payment platforms, holding regulatory licenses from the Central Bank of Nigeria (CBN), the UK Financial Conduct Authority (FCA), and the Bank of Uganda — a rare multi-jurisdictional licensing achievement in African fintech. What the API Does The AZA Finance API, documented at docs.azafinance.com and accessed via the developer portal at developers.transferzero.com, enables developers to programmatically initiate and manage cross-border payments across 30+ currencies and 115+ markets. Core capabilities include: sending payouts to bank accounts, mobile money wallets (M-Pesa, MTN Mobile Money, Airtel), and cash pickup points; real-time FX conversion between African and major global currencies; bulk payment processing for high-volume disbursements; account validation before sending; and webhook callbacks for real-time transaction status updates. How Developers Use It Developers integrate by creating an account at developers.transferzero.com. Authentication is via API Key and Secret issued from the portal. AZA Finance provides official SDKs for .NET, Java, JavaScript, PHP, and Ruby, significantly reducing integration time. The typical flow involves: creating a sender (KYC-verified entity), creating recipients (beneficiaries with bank or wallet details), initiating a transaction specifying corridors and currencies, and listening for webhook callbacks for status updates (pending, processing, paid, cancelled). The API supports test transactions in sandbox mode before going live. Supported Currencies and Countries AZA Finance supports 30+ currencies including NGN (Nigeria), GHS (Ghana), KES (Kenya), UGX (Uganda), TZS (Tanzania), ZAR (South Africa), XOF/XAF (CFA franc zones), MZN (Mozambique), USD, EUR, GBP, AED, CNY, and more. Nigeria is fully supported with CBN licensing in place. Pricing AZA Finance does not publish a public fee schedule. Pricing is determined by enterprise contract and depends on volume, corridor, and currency pair. The FX spread is embedded in the exchange rate offered. There is no self-serve free tier — you must contact their sales team to negotiate a contract. A sandbox environment is available for technical integration and testing at no cost. Authentication API authentication uses a Key + Secret pair obtained from the developer portal at developers.transferzero.com. Requests are signed with the secret to create an authorization header. The portal also supports role-based access controls for team members. Rate Limits AZA Finance operates on enterprise SLAs. Specific rate limit figures are not published publicly — they are determined by agreement. The platform maintains a 99.5% uptime guarantee. Compliance and Regulations AZA Finance is licensed by the Central Bank of Nigeria, making it one of the few Africa-focused payment APIs with direct CBN authorization. It also holds FCA authorization in the UK and Bank of Uganda licensing. The platform is PCI-DSS compliant and certified to ISO27001:2022 for information security management. All transactions undergo AML screening and compliance monitoring 24/7. Challenges and Gotchas Key limitations for Nigerian developers: (1) AZA Finance is B2B only — it is not designed for consumer checkout flows. (2) Pricing is opaque — you cannot estimate costs without contacting sales. (3) KYC onboarding can be lengthy for enterprise clients. (4) The developer portal still uses "TransferZero" branding from the previous product name — this can confuse developers unfamiliar with the company history. (5) No USSD or card payment support — AZA Finance is purely for push-payment corridors. Company Background AZA Finance was founded in 2013 as BitPesa, a Bitcoin-based remittance platform for Kenya. It later pivoted away from crypto, rebranded as TransferZero, and finally as AZA Finance in 2020. The company is headquartered in Nairobi with offices in Lagos, London, Madrid, Luxembourg, and Dakar. It has processed over $3 billion in transactions and serves major clients including global remittance firms and banks. FAQs Q: Can a Nigerian startup use AZA Finance without CBN licensing? A: Yes. AZA Finance holds the CBN license on your behalf — you access their infrastructure without needing your own license. However, you must sign a partner agreement and pass their KYC checks. Q: Is there a sandbox for testing? A: Yes. Developers can test at developers.transferzero.com in sandbox mode before production. Q: Does AZA Finance support NGN? A: Yes. Nigerian Naira (NGN) is a core supported currency with payouts to all major Nigerian banks. Q: Is AZA Finance suitable for consumer apps? A: No. AZA Finance is built for B2B use — enterprises, fintechs, and money transfer operators. It does not offer a consumer-facing checkout widget or SDK.

109. PayVessel Payments & Virtual Cards API

Payments

PayVessel Payments and Virtual Cards API is a Nigerian fintech infrastructure platform that provides a unified API covering payment collection, bank transfers, virtual accounts, virtual card issuance, identity verification, and credit scoring for Nigerian digital businesses. PayVessel consolidates multiple fintech building blocks into a single integration, enabling Nigerian startups and platforms to launch with comprehensive payment and financial infrastructure without stitching together multiple separate providers. Payment collection through PayVessel supports the primary Nigerian payment methods: card payments (Visa, Mastercard, Verve), bank transfers via virtual accounts, and mobile wallet payments. Merchants and platforms integrated with PayVessel can accept payments from Nigerian customers through any of these channels from a single API integration, ensuring that customers can pay using whichever method is most convenient or available to them without the merchant maintaining multiple payment gateway integrations. Dynamic virtual accounts are a core feature of PayVessel's collection infrastructure. A dynamic virtual account is a unique bank account number generated on demand for a specific payment transaction. When a customer is shown a dynamic virtual account number at checkout, any transfer made to that account number within a defined time window is matched to the specific transaction and triggers payment confirmation. Dynamic accounts solve the reconciliation problem of bank transfers — traditionally, matching a transfer received from an unknown sender to a specific order required manual matching; dynamic accounts automate this matching completely. Virtual USD cards issued through PayVessel enable Nigerian platform users to make USD-denominated online purchases, pay for international subscriptions, and receive USD payments through a virtual card with a US Mastercard number. For Nigerian users who need to access global digital services — cloud computing platforms, international software subscriptions, overseas supplier payments — a virtual USD card provides access without requiring a traditional domiciliary account or the foreign exchange procurement challenges associated with it. BVN (Bank Verification Number) verification through PayVessel enables platforms to verify that a customer's provided name and BVN match the records in the NIBSS database, confirming identity and banking status. NIN (National Identification Number) verification similarly validates identity against the NIMC database. For Nigerian lending platforms, savings apps, and investment platforms with regulatory Know Your Customer (KYC) requirements, BVN and NIN verification through PayVessel provides the identity confirmation layer needed for onboarding compliance. Credit scoring capabilities within PayVessel derive risk signals from customer transaction patterns, bank verification data, and behavioral indicators to produce credit scores that lending platforms can use for automated underwriting decisions. For Nigerian platforms offering buy-now-pay-later, micro-loans, or salary advances, an embedded credit scoring signal reduces the reliance on subjective human judgment in loan decisions and enables faster, more consistent approval workflows. Bulk transfer capabilities allow platforms to initiate large numbers of individual bank transfers in a single API request, enabling mass disbursement of funds — salary payments, affiliate commissions, vendor settlements, refund processing — without making individual API calls for each recipient. Nigerian HR platforms, marketplace operators, and financial services businesses that disburse to thousands of recipients regularly use bulk transfer APIs to complete disbursement cycles in minutes rather than hours of individual transaction processing. PayVessel provides a sandbox test environment where developers can simulate all API operations with test credentials before going live. The test environment produces realistic responses for successful and failed transaction scenarios, enabling thorough integration testing that validates edge case handling without affecting real bank accounts or processing real money during development.

110. VTUGate API

Utility Tools, Payments

Nigerian VTU platform providing unified API for airtime, data, cable subscriptions, and electricity bills. VTUGate specializes in high reliability through integration with multiple VTU providers as backup. Single API integration connects to multiple providers ensuring uptime and redundancy.

111. Nium Payout API

Payments, Development Tools

Nium is a Singapore-headquartered global payments infrastructure company that provides businesses with a unified API to send payments to 190+ countries, collect payments in 35+ markets, and issue physical and virtual cards in 30+ countries. Nium is a licensed financial institution in multiple jurisdictions including the US, UK, EU, Singapore, and Australia, and serves financial institutions, fintech companies, banks, and enterprises that need to build or scale cross-border payment capabilities. The Nium API is RESTful with JSON payloads. Documentation is at docs.nium.com. Authentication uses API Key credentials passed in request headers (client-id and x-api-key). Nium operates a payout platform (mpdocs.nium.com) that provides the most detailed technical integration guidance for developers building payment products. For payouts, Nium supports 190+ destination countries with 65 of those available in real-time. The supported corridors span the Americas, Europe, Middle East, Africa, Oceania, and Asia-Pacific. Nigeria falls within Nium's Africa coverage — however, the exact payment methods, corridors, and processing times for Nigeria should be confirmed via the Nium Playbook at playbook.nium.com before integration. Payout fees are calculated in real-time at transaction execution and are corridor-specific. For collections, Nium supports receiving payments in 35+ markets using local payment methods. This covers bank transfers, card payments, and local e-wallets depending on the market. Nigeria-specific collection support should be confirmed separately. Nium also offers card issuance APIs in 30+ countries — enabling fintechs and banks to issue virtual and physical Visa/Mastercard cards to their customers. Cards can be issued in multiple currencies and managed programmatically (freeze, unfreeze, set spending limits, retrieve transactions). Webhooks are available for all major events: payout processing, payout completion, payout failure, and card transaction alerts. Developers can configure webhook endpoints during Nium account setup. The sandbox environment provides full testing capability for all Nium products. Moving to live requires completing Nium's enterprise onboarding, including business verification and compliance review by a Nium account manager. From a compliance standpoint, Nium is regulated in multiple jurisdictions globally. The company holds money transmitter licenses in all US states, FCA authorization in the UK, Payments Institution license in the EU, and MAS Major Payment Institution license in Singapore. For transactions to/from Nigeria, Nium routes through local correspondent partners that are CBN-licensed. Nium raised $200 million at a $2.1 billion valuation in 2022, making it one of the most well-capitalized global payment infrastructure companies. Clients include large banks, digital banks, travel companies, and enterprise platforms globally. Frequently Asked Questions: Is Nigeria a supported payout destination on Nium? Nium covers 190+ countries including African markets. Nigeria is likely included, but specific corridor availability and payment methods should be confirmed via the Nium Playbook at playbook.nium.com or by contacting your Nium account manager. Does Nium support NGN as a settlement currency? This should be confirmed during Nium onboarding. Nium typically settles in the destination country's local currency. Is Nium self-service or enterprise? Nium is primarily enterprise — access requires working with a Nium account manager. It is not a self-service sign-up API like Paystack or Stripe. Nium's card issuance capability in 30+ countries allows platforms to issue Visa or Mastercard branded cards to their customers in multiple markets from a single API integration. For Nigerian fintechs building pan-African or global financial products, Nium's card issuance infrastructure provides the card product layer alongside payout and collection capabilities, enabling a more complete financial product stack without multiple card program relationships. Nium's treasury management features allow platforms to hold multi-currency balances, execute FX conversions between 35+ currencies at competitive rates, and manage currency exposure across the markets they operate in. For Nigerian platforms managing collections in multiple currencies and disbursements in NGN or other African currencies, centralized multi-currency treasury management through Nium reduces FX conversion costs and the operational complexity of managing multiple currency accounts across different banking relationships.

112. Jostpay API

Development Tools, Payments

Nigerian payment gateway and VTU (airtime/data) platform API for merchants and resellers. Provides payment processing, bill payments, and mobile top-up services. Legacy platform with stable but limited recent API development activity.

113. Mainstack API

Payments

Mainstack is a Nigerian fintech platform providing embedded payments, business tools, and payout APIs for entrepreneurs and SMEs. The Mainstack API enables payment processing, fund management, and business automation. Nigerian entrepreneurs, creators, and SMEs use Mainstack to accept payments, manage funds, and access embedded finance.

114. dRPC

Blockchain

dRPC is a decentralized RPC load balancer that aggregates multiple blockchain node providers into a single endpoint, routing requests across different providers for redundancy, load balancing, and censorship resistance. Instead of depending on a single node provider like Alchemy or Infura, dRPC routes each RPC call through its network of node providers — automatically failing over to alternative providers if any individual provider experiences downtime or rate limiting. This multi-provider architecture makes dRPC one of the most reliable options for high-availability blockchain connectivity. For Nigerian Web3 developers, dRPC offers a very generous free tier of 100 million API calls per month — substantially more than Alchemy (300M compute units, which translate to fewer calls for complex methods) or Infura (100K requests/day). This high free limit makes dRPC well-suited for Nigerian applications with high request volumes, particularly analytics tools or monitoring systems that query the blockchain frequently. The decentralized routing model means that no single provider failure can take down a dRPC-connected application. Requests are distributed across multiple providers including Alchemy, QuickNode, Infura, and others depending on availability and latency, with the routing logic handled by dRPC's infrastructure. For Nigerian production applications where uptime is critical, this redundancy provides a meaningful reliability advantage over single-provider connections. Support covers 30+ EVM chains including Ethereum, Polygon, Arbitrum, Optimism, Base, BNB Smart Chain, and Avalanche, with WebSocket endpoints for real-time subscriptions. The free tier provides shared endpoint access, while paid plans offer dedicated endpoints with higher throughput guarantees and the ability to prefer specific underlying providers. For Nigerian developers evaluating node providers, dRPC is particularly compelling when: (1) free tier request volume is a primary concern, (2) maximum uptime through provider redundancy is valued, or (3) decentralization and censorship resistance are architectural priorities. For developers who prioritize enhanced APIs (NFT data, wallet portfolios) over raw RPC, Moralis or Alchemy provide richer data endpoints. dRPC's distributed routing layer intelligently selects the best available node for each request based on latency, error rate, and load — delivering higher effective reliability than single-provider endpoints by automatically failing over to alternative nodes when any individual node underperforms. This self-healing architecture is particularly valuable for production DApps where downtime directly affects user trust. The platform supports both HTTPS and WebSocket connections, with WebSocket being essential for real-time features like block subscription, event listeners, and transaction status tracking in DApp interfaces. Stable WebSocket connections prevent the reconnection overhead that degrades real-time user experience. For Nigerian Web3 startups building production applications, dRPC's combination of generous free usage, multi-chain coverage, and reliability improvements over single-provider alternatives makes it an operationally sound choice. The provider-agnostic routing means that if any single underlying node provider has issues, dRPC's routing automatically compensates, maintaining service availability for Nigerian end users accessing the DApp. API key management is straightforward through the dRPC dashboard, with separate keys for different environments (development, staging, production) enabling proper segregation of traffic and usage monitoring by environment.

115. Binance API

Development Tools, Blockchain, Trading & Currency Exchange

Binance API provides programmatic access to the world's largest cryptocurrency exchange by trading volume, covering market data, spot trading, futures trading, margin trading, and account management. The Binance API is comprehensive and well-documented, with REST endpoints for all trading operations and WebSocket streams for real-time order book updates, trade feeds, and account notifications. For developers building trading bots, portfolio trackers, and crypto market data tools, Binance is often the primary exchange to integrate given its unmatched liquidity and the breadth of listed trading pairs. However, Nigerian developers and users should be clearly aware of an important service restriction: Binance.com suspended its services for Nigerian users in 2024 following regulatory and compliance disputes. Nigerian residents cannot create new accounts on Binance.com, and Nigerian users who previously held accounts face restrictions on deposits, withdrawals, and trading. This makes Binance.com effectively unavailable for Nigerian end users. The Binance API is listed here for completeness and for developers building applications for non-Nigerian markets, but Nigerian-focused applications should not depend on Binance.com as a platform for their Nigerian users. For developers outside Nigeria, or for Nigerian developers building tools for international users, the Binance API covers the full range of exchange functionality. The market data endpoints are publicly accessible without authentication — any developer can query current prices, order book depth, recent trades, 24-hour statistics, and OHLCV candlestick data for any of Binance's hundreds of trading pairs without an API key. This public market data layer is commonly used by price aggregators, portfolio trackers, and market analysis tools. The REST API uses a weight-based rate limiting system where different endpoints consume different amounts of "weight" from a per-minute budget. Lightweight endpoints like price queries consume 1 weight, while heavier endpoints like full order book snapshots consume more. The default limit is 1,200 weight per minute per IP, which is generous for most applications. Trading endpoints additionally have per-account order rate limits. WebSocket streams provide real-time data: individual symbol trade streams, order book depth updates (full snapshots and incremental updates), candlestick streams, and account-level streams for order updates and balance changes. For algorithmic trading systems, WebSocket streams are essential for maintaining a real-time view of market state without polling overhead. Trading operations via authenticated API endpoints cover the full lifecycle: placing market, limit, stop-loss, and take-profit orders; querying open orders; cancelling orders; and retrieving order history. Futures trading on Binance USD-M and COIN-M futures markets is accessible through separate API endpoints with similar authentication and structure. The Binance Testnet (testnet.binance.vision) provides a sandbox environment for testing trading bot logic without risking real funds. Test funds are available from the testnet faucet, and the testnet API behaves identically to production for most operations. For Nigerian developers who need a similar exchange API for applications targeting Nigerian users, alternatives include Coinbase Advanced Trade API (for US-compliant markets), Kraken API, or Nigerian-local exchanges such as Busha Commerce API — all of which are listed separately in this directory and serve users in Nigeria without the geographic restrictions applicable to Binance.com.

116. eTranzact

Banking & Fintech, Payments

eTranzact International Plc is one of Nigeria's oldest and most established fintech companies, listed on the Nigerian Stock Exchange (NSE).

A sandbox environment is available for testing. Pricing Enterprise pricing only — not publicly listed. eTranzact targets institutional clients with contracts negotiated based on integration type, transaction volume, and product combination. Contact eTranzact for pricing. Compliance eTranzact is CBN-licensed and operates under CBN payment system regulations. As an NSE-listed company, it is subject to SEC regulations and public reporting requirements — providing institutional clients with a high level of corporate accountability and transparency. Challenges and Gotchas (1) Not a self-service platform — enterprise onboarding required. (2) Documentation is less accessible than Paystack or Flutterwave. (3) Primarily institutional focus — not designed for individual developers or small startups. (4) Pricing requires sales engagement. (5) Product suite is broad but each product may require a separate integration agreement. Company Background eTranzact International Plc was incorporated in 2003 and is headquartered in Lagos. It is listed on the Nigerian Stock Exchange and serves over 200+ banks and financial institutions across Nigeria and Africa. The company has expanded into Ghana, Zimbabwe, and other African markets. Its longevity and stock exchange listing make it one of the most trusted institutional payment infrastructure providers in Nigeria. FAQs Q: Is eTranzact publicly listed? A: Yes. eTranzact International Plc is listed on the Nigerian Stock Exchange. Q: Can a startup integrate eTranzact independently? A: eTranzact is primarily enterprise-focused. Small startups should consider Paystack or Flutterwave as more accessible alternatives. Q: Does eTranzact support loan mandate processing? A: Yes. The AntPeer product handles loan mandate setup and automated repayment debit for digital lenders and microfinance banks. Q: What is WaaS? A: Wallet-as-a-Service — an API that lets third-party apps embed NGN wallet functionality without building their own wallet infrastructure. For Nigerian enterprises and large organizations, eTranzact's position as a publicly listed company on the Nigerian Stock Exchange provides a level of transparency and financial accountability that private fintech providers cannot match. Annual financial reports, board governance, and shareholder accountability create institutional confidence for Nigerian banks, government agencies, and large corporations selecting payment infrastructure partners for critical financial operations. NIBSS NIP integration through eTranzact enables real-time instant payment transfers between Nigerian bank accounts, settled within seconds. For enterprises running high-value payment operations — salary disbursements, vendor settlements, inter-company transfers — access to the NIP instant payment rail through eTranzact's regulated infrastructure ensures funds reach recipients immediately rather than in batch settlement windows. eTranzact's long-standing position as a NIBSS-licensed institution provides direct connectivity to Nigeria's core payment clearing infrastructure. The PTSA (Payment Terminal Service Aggregator) license held by eTranzact allows the company to aggregate POS terminal services and provide terminal deployment, management, and transaction routing for merchants. Nigerian businesses deploying POS infrastructure — retail chains, hotels, supermarkets, service businesses — can use eTranzact as their PTSA for terminal provisioning and ongoing support. This physical payment infrastructure layer complements eTranzact's digital API services for businesses managing both in-person and online payment channels.

117. Monierate

Blockchain, Trading & Currency Exchange

Monierate is a Nigerian-built exchange rate aggregation platform and API that solves a uniquely Nigerian problem: the existence of multiple, often dramatically different, NGN exchange rate markets operating simultaneously. Unlike global exchange rate APIs (ExchangeRate-API, CurrencyLayer, Currencyapi) that only provide official mid-market rates, Monierate tracks and aggregates three distinct types of Nigerian Naira exchange rates — Official CBN rates, Midmarket rates, and Black Market (parallel market) rates — from over 40 Nigerian exchanges, Bureau de Change operators, banks, and cryptocurrency platforms. This multi-source, multi-market approach makes Monierate the most Nigeria-relevant exchange rate data source available, and the only API on the market specifically designed around the reality of Nigeria's dual exchange rate system. **Why Nigeria Needs a Dedicated FX API** Nigeria's foreign exchange market is uniquely complex. For extended periods, the country has operated a dual exchange rate system where the official CBN rate differs significantly from the rate available in the parallel market (also called the "black market" or "street rate"). This gap has at times exceeded 50–100% — meaning a developer using an international exchange rate API that only provides the official rate would be presenting rates that Nigerian consumers and informal businesses do not actually transact at. For Nigerian fintech apps, remittance platforms, crypto exchanges, and financial media that serve real users in Nigeria, the parallel market rate is often more relevant than the official rate. Monierate is built specifically to address this gap. **What Monierate Provides** The Monierate API aggregates NGN exchange rate data from 40+ sources and provides: 1. **Official CBN Rates**: The Central Bank of Nigeria's official exchange rates — the rate used for official transactions, government imports, and regulated financial institutions. 2. **Midmarket Rates**: The average market rate between buy and sell prices across major providers — a middle-ground figure useful for general currency conversion displays. 3. **Parallel Market (Black Market) Rates**: The street rates available through Bureau de Change operators and informal channels — reflecting what Nigerian individuals and businesses actually transact at when official channels are unavailable or uncompetitive. 4. **Crypto Exchange Rates**: NGN prices from major crypto exchanges including Binance and Bybit — enabling apps to display Bitcoin, Ethereum, and USDT values in Naira at current exchange platform rates. **40+ Source Aggregation** Monierate continuously monitors exchange rates from over 40 Nigerian and international providers including: CBN (Central Bank), commercial banks, Bureau de Change operators, crypto exchanges (Binance, Bybit), remittance services, and financial platforms. This aggregation gives developers access to rate comparison data across providers — not just a single rate but a full market picture. **API Authentication & Access** Monierate requires an account signup to access the API, even on the free plan. Account creation is done at monierate.com/api and requires only an email address — no KYC or business verification. An API key is issued upon signup. Developers pass this key in their API requests to authenticate. **Pricing** Monierate offers a free plan with standard rate limits suitable for development and low-traffic applications. Paid plans with higher rate limits are available for production-scale usage. Specific pricing tiers and request volumes require account registration to view. Rate limiting is enforced at the plan level, not per request. **Use Cases in Nigerian Context** Monierate is the data source of choice for any Nigerian application where accuracy of the real-world exchange rate matters: - Remittance comparison tools showing which service gives the best NGN rate - P2P crypto platforms displaying USDT/NGN and BTC/NGN rates - Financial news sites embedding live Naira rate widgets - Treasury management tools monitoring official vs. parallel rate spreads - Travel apps showing travelers what to expect at Lagos Bureau de Change desks - Import/export businesses calculating true FX costs beyond official rates **Comparison with Global FX APIs** While ExchangeRate-API, CurrencyLayer, and Currencyapi provide official mid-market NGN rates that may be accurate for international financial reporting, they are insufficient for building consumer-facing Nigerian financial apps where users experience the parallel market daily. Monierate fills this gap by providing the data that represents how Nigerian users actually experience exchange rates. **Company Background** Monierate was built by Nigerian developers to solve the local FX data problem. The platform operates as both a consumer-facing website (monierate.com) where Nigerians can track live rates and compare providers, and as an API service for developers who want to embed those rates into their own applications. **Frequently Asked Questions** Q: What makes Monierate different from ExchangeRate-API? A: Monierate provides Nigerian parallel market and black market NGN rates — which no global exchange rate API includes. ExchangeRate-API only provides official mid-market rates. Q: Do I need to pay to use the Monierate API? A: A free plan is available with email signup. Paid plans provide higher rate limits for production use. Q: Does Monierate support non-NGN currency pairs? A: Monierate is focused on Nigerian Naira (NGN) exchange rates. For multi-currency pairs not involving NGN, use a global exchange rate API. Q: Does it include crypto rates? A: Yes. Monierate tracks NGN prices on Binance, Bybit, and other crypto exchanges. Q: How many sources does Monierate aggregate? A: Over 40 Nigerian exchanges, BDCs, banks, crypto platforms, and remittance services.

118. OPay

Payments, Development Tools

OPay is a Nigerian digital financial services company and CBN-licensed Payment Service Bank that provides payment gateway APIs for businesses to accept online and offline payments. Originally founded as Opera Pay, OPay has grown into one of Nigeria's largest fintech platforms, backed by SoftBank Vision Fund 2, Sequoia Capital China, and other major investors. OPay operates the largest mobile money network in Nigeria with over 40 million registered users and hundreds of thousands of agents — making it unique among Nigerian payment gateways in that its checkout is also deeply integrated with a mass-market e-wallet used daily by tens of millions of Nigerians. The OPay Checkout API is a RESTful, PCI-compliant payment gateway that enables businesses to accept multiple payment methods through a single integration. Developers access the API documentation at doc.opaycheckout.com, which provides both a hosted Express Checkout option (where OPay handles the entire payment UI) and a Server-to-Server API option (where developers build their own payment UI and call OPay endpoints directly for full control over the customer experience). Authentication uses AppId and AppKey credentials from the OPay Business Dashboard. Requests are signed using HMAC for security. The AppId is passed in the request header, and the AppKey is used to generate a signature that validates the integrity of each API call. The Business Dashboard is also used to configure webhook URLs and IP whitelisting — both of which are required for production deployments. OPay supports the following payment channels for Nigeria: local debit card payments (3DS and non-3DS), bank transfer checkout (where customers receive a virtual account number to transfer to), USSD payments, bank account direct debit, and OPay e-wallet QR payments. The e-wallet QR channel is uniquely powerful — customers with the OPay app can scan a QR code to pay directly from their OPay wallet, and the cost to the merchant is just ₦5 per transfer (the lowest payout rate in the Nigerian market). On the pricing side, OPay charges 1.5% per local transaction capped at ₦2,000 — identical to Paystack and Monnify. International card transactions are charged at 4% with no cap. For payouts (transfers out), OPay wallet transfers cost ₦5 flat, while bank transfers to other Nigerian banks follow the industry standard: ₦10 for amounts up to ₦5,000, ₦25 for ₦5,001–₦50,000, and ₦50 above ₦50,000. Volume discount pricing is available for large-volume processors upon request. OPay also provides a WooCommerce plugin for WordPress-based e-commerce stores, enabling non-technical merchants to add OPay checkout without writing any code. A PHP SDK is also available for backend developers. Webhook notifications are available for payment confirmation events. Developers must configure webhook endpoints in the dashboard and validate webhook signatures to prevent fraudulent event injection. OPay's sandbox environment allows full testing of all payment channels before going live. Moving to live requires completing OPay's business onboarding including CBN KYC: CAC registration, director BVN and government ID, and a business bank account. From a compliance standpoint, OPay Digital Services Limited is CBN-licensed as a Payment Service Bank and operates under the Payment Service Bank (PSB) regulatory framework. All card data is processed in compliance with PCI-DSS. The OPay e-wallet is NDIC-insured up to ₦500,000. Known challenges: OPay's developer documentation is less comprehensive than Paystack's. Some advanced features (split payments, recurring billing) are not available. The e-wallet QR payment channel requires customers to have the OPay app installed, which is only relevant for merchants targeting OPay's user base. Frequently Asked Questions: How is OPay different from Paystack? OPay's main differentiator is the integration with its 40M+ user e-wallet for ₦5 QR payments. For developers building for OPay's mass-market user base, this is a significant advantage. For general e-commerce, Paystack has better documentation and more developer features. Does OPay support split payments or subscriptions? No — OPay's checkout API does not currently support split payments or recurring subscription billing. What is the OPay wallet QR payment? It allows merchants to display a QR code that customers with the OPay app can scan to pay directly from their OPay wallet at ₦5 per transaction.

119. GT Pay (GTPay)

Payments, Banking & Fintech, Development Tools

GTPay is the online payment gateway from Guaranty Trust Bank (now Guaranty Trust Holding Company — GTCo), one of Nigeria's largest and most recognized tier-1 banks. GTPay enables Nigerian merchants to accept card payments online from customers using Interswitch (Verve), Visa, and Mastercard — both locally issued and international cards. The gateway is backed by GTBank's banking infrastructure and has been serving Nigerian e-commerce merchants since the early days of online payments in Nigeria. What GTPay Does GTPay processes card-present-not-required (CNP) transactions for online merchants, collecting payment from customers and settling into the merchant's GTBank business account. The gateway supports NGN (currency code 566) and USD (currency code 840) transactions, making it usable for both local NGN e-commerce and international USD billing. How Developers Use It Developers obtain a Merchant ID and Hash Key by physically visiting any GTBank branch nationwide and registering as a GTPay merchant. After registration, integration is done using the technical parameters documented at ibank.gtbank.com/gtpay/IntegrationAPI/mman-tech.html. Key parameters include: gtpay_mert_id (merchant identifier), gtpay_tranx_id (unique transaction ID from merchant), gtpay_tranx_amt (amount in kobo or cents), and gtpay_tranx_curr (ISO currency code — 566 for NGN, 840 for USD). The Hash Key is used to generate a transaction hash for request signing. Pricing Local card transactions: 1.5% fee capped at ₦2,000. Contact GTBank for the full fee schedule including international card rates. Authentication Merchant ID and Hash Key pair obtained from GTBank branch. Transactions are signed using the Hash Key to generate a security hash that GTBank validates before processing. Compliance GTPay is operated by Guaranty Trust Bank (CBN-licensed), ensuring full CBN compliance for all payment processing. PCI DSS compliant for card data handling. Important Note on Legacy Status GTCo (formerly GTBank) has since launched Squad (squadco.com) as their modern, developer-first payment platform under HabariPay Limited. Squad offers a comprehensive REST API with sandbox, webhooks, virtual accounts, and full documentation. For new integrations, Squad is the recommended modern alternative to GTPay. GTPay remains operational for existing merchants. Challenges and Gotchas (1) Merchant registration requires a physical GTBank branch visit — not self-serve online. (2) GTPay is a legacy product — documentation is older and less comprehensive than modern gateways. (3) No bank transfer, USSD, or recurring billing support. (4) Integration is form-post based rather than modern REST JSON API. (5) New projects should seriously consider Squad (HabariPay) instead. FAQs Q: How do I get a GTPay Merchant ID? A: Visit any GTBank branch nationwide with your business documents to register as a GTPay merchant. Q: Is GTPay still active? A: Yes, GTPay remains operational for existing merchants but GTCo's newer platform Squad is the recommended modern alternative. Q: Does GTPay support USSD or bank transfer? A: No. GTPay only supports card payments (Interswitch/Verve, Visa, Mastercard). Q: What currencies does GTPay support? A: NGN (566) and USD (840). GTPay's backing by Guaranty Trust Bank (GTBank) — consistently ranked among Nigeria's top tier-1 banks — provides GTPay merchants with the financial security and institutional credibility that bank-affiliated payment infrastructure carries. For Nigerian businesses where their payment gateway provider's financial stability is a selection criterion — particularly for merchants holding float or awaiting settlement — a bank-affiliated gateway provides assurance that is difficult for independent fintech providers to match. The settlement process for GTPay transactions credits merchant accounts within GTBank's settlement cycle, with same-day or next-day settlement available for GTPay merchants who also hold GTBank business accounts. This tight integration between payment gateway and bank account reduces settlement float and simplifies reconciliation for merchants whose primary banking relationship is with GTBank, one of the largest retail and commercial banking relationships in Nigeria.

120. CBI Monie

Payments, Development Tools

CBI Monie is a Nigerian payment infrastructure platform operated by CBI Technologies Limited. The company is licensed by the Central Bank of Nigeria (CBN), ISO-certified, NDPR-compliant, and PCI-DSS certified — making it one of the compliance-ready options for Nigerian businesses and fintechs needing embedded payment capabilities. CBI Monie offers multi-channel payment acceptance including POS terminals, dynamic QR codes, virtual account numbers, payment links, and a developer API for programmatic integration. What the API Does The CBI Monie API provides RESTful endpoints for: wallet balance and transaction management; QR code and virtual account generation; merchant onboarding for agent networks; payment links and checkout sessions; and real-time webhook events for automated workflows. The API is designed for fintechs, ERP systems, government platforms, and agent network operators that need to embed payment infrastructure into their products. How Developers Use It API access is by request — developers contact support@cbitechnologiesltd.com to initiate onboarding. Once approved, API credentials are issued. The platform provides SDKs and webhook integration modules. A sandbox environment is available for safe testing of transactions and webhook events before going live. The API follows RESTful conventions. Pricing Not publicly listed. CBI Monie pricing is available upon request through their sales and support team at support@cbitechnologiesltd.com.

CBI Monie handles cardholder data in compliance with international payment security standards. All merchant and API partner onboarding includes KYC verification. Supported Payment Channels POS terminals (physical card-present), dynamic QR codes, virtual account numbers (NIP transfers), payment links and hosted checkout, and web/mobile integration via API. Challenges and Gotchas (1) API access is not self-serve — requires approval and manual onboarding. (2) No USSD payment support. (3) No crypto or cross-border payment capabilities. (4) Rate limits and detailed technical specs are not publicly documented. (5) Compared to Paystack or Flutterwave, documentation is less comprehensive and publicly accessible. Company Background CBI Monie is a product of CBI Technologies Limited, a Nigerian fintech infrastructure company. The platform targets enterprise and institutional clients including government agencies, large merchants, fintechs building on top of their rails, and agent network operators who need a compliant multi-channel payment stack. FAQs Q: How do I get API access? A: Contact support@cbitechnologiesltd.com to request API access. Access is not self-serve. Q: Is there a sandbox? A: Yes. CBI Monie provides a developer-safe sandbox for testing transactions and webhooks. Q: Is CBI Monie suitable for a consumer app? A: Yes, through the wallet and virtual account APIs. It is also well-suited for B2B and enterprise platforms. Q: Does CBI Monie accept international cards? A: Yes. POS and card acceptance includes Verve, Visa, and Mastercard. Q: Can CBI Monie handle agent network onboarding? A: Yes. The Merchant Onboarding API is specifically designed for programmatically onboarding agents at scale. The PCI DSS certification of CBI Monie ensures that card data processed through the platform meets the Payment Card Industry Data Security Standard requirements for cardholder data protection. For Nigerian fintechs and enterprises concerned about compliance with card scheme requirements, CBI Monie's certified status removes the burden of achieving independent PCI DSS certification for card data handling within the integrating platform's environment. QR code payment functionality in CBI Monie enables merchant-displayed QR codes that customers can scan to initiate payments using their mobile banking apps or fintech wallets. As QR code payment adoption grows in Nigeria — driven by CBN's promotion of cashless payment infrastructure and the expansion of mobile banking usage — merchants integrated with CBI Monie can offer this payment channel alongside traditional card and bank transfer methods without additional infrastructure. Merchant onboarding APIs within CBI Monie allow platform operators managing merchant networks to programmatically onboard new merchants, verify their identity and business credentials, and activate payment acceptance — building automated merchant lifecycle management for agent banking platforms, marketplace operators, and payment aggregators managing large merchant portfolios in Nigeria.

121. Squad

Payments, Development Tools

Squad is a Nigerian payment gateway and developer-first payment infrastructure platform operated by HabariPay Limited, the fintech subsidiary of Guaranty Trust Holding Company (GTCO) — the parent company of Guaranty Trust Bank, one of Nigeria's Tier 1 commercial banks. This institutional backing gives Squad a unique position in the Nigerian fintech ecosystem: it combines the regulatory standing of a CBN-licensed commercial bank group with a modern API-first developer experience. Squad is available at squadco.com and provides documentation at docs.squadco.com. The Squad API is RESTful with JSON payloads. Authentication is via Bearer Token — developers obtain a secret key from the Squad dashboard and pass it in every request as Authorization: Bearer sk_test_xxxx (sandbox) or Authorization: Bearer sk_live_xxxx (production). All amounts are passed in Naira (NGN), unlike some Nigerian gateways that require amounts in Kobo. Squad's payment gateway supports card payments (Verve, Visa, Mastercard), bank transfers, and USSD — the three primary payment channels used by Nigerian consumers. The standard integration follows a three-step flow: initialize a transaction by posting to the Squad initiate endpoint with amount, email, and a unique transaction reference; display the Squad checkout widget to the customer; and verify the transaction on your server after the customer completes payment. Squad provides both a hosted checkout page and an embeddable inline SDK for seamless checkout experiences. One of Squad's most notable differentiators is its fee structure. The payment gateway charges a percentage fee capped at ₦1,500 per transaction — lower than Paystack (₦2,000 cap) and Monnify (₦2,000 cap). For virtual account collections, Squad charges a percentage capped at ₦1,000, which is again among the lowest caps in the Nigerian market for bank transfer collections. Payment links (used for social commerce and invoicing) are charged at 1% for local transactions and 3.5% for international transactions. This pricing advantage makes Squad particularly attractive for businesses processing high-value transactions, where the cap limits the absolute cost per transaction regardless of size. Squad's Virtual Accounts feature assigns a dedicated bank account number to each customer for use in collections. Businesses can create virtual accounts for individual customers — when a customer transfers any amount to their dedicated account, the Squad webhook fires and the balance is credited in real time. This is widely used by Nigerian savings apps, investment platforms, and bill payment services where customers top up wallets via bank transfer. The Subscription API allows platforms to create recurring billing products. When a customer first pays via Squad, the platform receives a unique charge token tied to that customer's card. Future charges can be triggered by passing this token without requiring the customer to re-enter card details — enabling automatic monthly subscriptions, usage-based billing, and installment plans for Nigerian consumers. Squad also provides a Payouts API for disbursing funds to any Nigerian bank account. Developers submit a destination bank code, account number, and amount, and Squad executes the transfer. Payout pricing is competitive and the API supports both single and bulk transfers. The BVN verification endpoint available through Squad allows platforms to look up a Bank Verification Number and return the associated name and basic identity information. This is commonly used by Nigerian lending products and fintech apps to confirm user identity as part of CBN-required KYC processes. The Squad sandbox environment provides full test mode access. Developers can test all features — gateway payments, virtual accounts, subscriptions, payouts, and BVN verification — using test credentials without processing real transactions. Moving to live requires completing Squad's business onboarding, including submitting CAC registration, director BVN, and a valid business bank account. From a compliance perspective, HabariPay Limited is a CBN-licensed Payment Service Provider operating under the regulatory oversight of the Central Bank of Nigeria. GTCO's banking license adds an additional layer of institutional compliance. Squad is also PCI-DSS certified, ensuring that card payment data is processed and stored to the highest security standards. Squad runs an annual Hackathon for Nigerian students and early-career developers — Squad by GTBank Hackathon — providing cash prizes and API credits to winners. This investment in the developer community has built significant goodwill among Nigeria's emerging developer ecosystem. Known challenges: Squad's documentation, while functional, is less comprehensive than Paystack's. Some advanced integration patterns (split payments, multi-vendor marketplace flows) are not as fully documented. The Squad developer community is smaller than Paystack's, which can make troubleshooting harder for niche use cases. Frequently Asked Questions: Is Squad backed by GTBank? Yes — Squad is operated by HabariPay Limited, which is a subsidiary of Guaranty Trust Holding Company (GTCO), the same holding company that owns GTBank. What is the fee cap advantage? Squad's gateway fee is capped at ₦1,500 versus ₦2,000 for Paystack and Monnify — meaning on large transactions, you save ₦500 per collection. Does Squad support dollar transactions? Squad supports international card payments (Visa/Mastercard). Settlement is in NGN. Can I test Squad without registering a business? Yes — create a free developer account and use the sandbox with test credentials before submitting any business documents.

122. NumlookupAPI Phone Validation

Data Validation, Development Tools, Payments

NumlookupAPI is a phone number lookup and validation API providing real-time carrier identification, line type detection, geographic location data, and number format normalization for global phone numbers including Nigerian (+234) numbers. Operated by EverAPI (everapihq), the platform offers a developer-friendly integration path with a free trial requiring no credit card, paid plans from $9.99/month, and a 99.99% uptime SLA on all paid tiers. The API is designed for businesses that need to validate phone numbers at point of entry, enrich CRM contact data, or screen registrations for invalid or suspicious numbers — without the complexity of a full communications platform. ## What the API Does A single NumlookupAPI call accepts a phone number and returns: - **Validity**: Whether the number is a valid, recognized phone number. - **Number (E.164)**: The number in international E.164 format. - **Carrier**: The mobile network operator (e.g., MTN Nigeria, Airtel Nigeria, Globacom, 9mobile). - **Line type**: Mobile, landline, VoIP, or unknown. - **Location**: Country and sub-national region associated with the number prefix. - **Country code**: ISO 2-letter country code (NG for Nigerian numbers). The API integrates with CRM systems, marketing platforms, and custom applications for automated phone number quality management. ## How Developers Use It GET request to the NumlookupAPI endpoint with the phone number and API key. The response is a JSON object with all available metadata. SDKs and client libraries are available for popular languages through the GitHub repository (everapihq/numlookupapi). Integration is straightforward and can be completed in under an hour. ## Pricing & Fees - **Free trial**: Available with no credit card required for initial testing. - **Paid plans**: Start at $9.99/month providing 7,000 API requests per month. - **Custom plans**: Available for businesses requiring more than 300,000 requests per month. - All paid plans include unlimited API connections (no concurrent request limit) and the 99.99% uptime guarantee. ## Authentication API key authentication. The key is passed as a parameter in the API request. Keys are issued immediately after registration. ## Rate Limits Rate limits are based on monthly request quotas per plan tier. Paid plans come with unlimited concurrent API connections — requests are processed without queuing. Monthly quotas reset each billing cycle. ## Compliance NumlookupAPI processes phone numbers for validation and lookup purposes. Data handling policies are consistent with standard API service agreements. For Nigerian deployments, the carrier and format data returned supports phone number verification as part of broader user onboarding flows. ## Challenges & Gotchas for Nigerian Developers 1. **No SIM Swap detection**: NumlookupAPI provides carrier and line type data but does not offer SIM Swap detection for fraud prevention. Use Twilio Lookup for SIM Swap signals. 2. **Carrier accuracy with MNP**: Nigerian mobile number portability can cause carrier misidentification after a user switches networks. The API reflects original carrier assignment. 3. **7,000 requests at $9.99**: This is a reasonable starting volume but will be exhausted quickly for apps with active daily registrations. Plan your tier based on expected daily validation volume. 4. **USD billing**: NumlookupAPI charges in USD. Nigerian developers need a USD-capable payment method. 5. **Limited documentation depth**: As a smaller API provider, documentation and community support resources are more limited than Twilio or Abstract API. ## Company Background NumlookupAPI is operated by EverAPI (everapihq), a developer-focused API company providing a portfolio of data enrichment and validation APIs. The platform is available as an open-source client library on GitHub and through the Rapid API marketplace in addition to the main website. ## Frequently Asked Questions **Q: Does NumlookupAPI support Nigerian phone numbers?** A: Yes. Nigerian numbers (+234) are supported with carrier identification for MTN, Airtel, Glo, and 9mobile. **Q: Is a credit card required to try the API?** A: No. A free trial is available without credit card details. **Q: What is the uptime guarantee?** A: Paid plans include a 99.99% uptime SLA over the trailing 12-month period. **Q: How many requests does the entry-level plan include?** A: The $9.99/month plan includes 7,000 API requests per month.

123. Stripe

Payments, eCommerce

Stripe is the world's leading developer-first payment infrastructure platform, offering a comprehensive suite of APIs for accepting payments, managing subscriptions, running marketplaces, issuing cards, and managing financial operations across 195+ countries. Stripe processes hundreds of billions of dollars annually for millions of businesses globally and is widely regarded as setting the gold standard for payment API design, documentation quality, and developer experience. CRITICAL NOTE FOR NIGERIAN BUSINESSES: Stripe does not currently support merchant account registration for Nigeria-incorporated businesses, NGN settlement to Nigerian bank accounts, or local Nigerian payment methods (bank transfers, USSD, Verve cards). Nigerian businesses cannot register a Stripe account as a Nigerian entity. Nigerian businesses needing local payment processing should use CBN-licensed alternatives: Paystack (Stripe subsidiary, Nigeria-optimized), Flutterwave, Monnify, Kora, or other Nigerian-licensed payment processors. However, Stripe remains highly relevant to the Nigerian tech ecosystem in several important capacities. Paystack — Nigeria's leading payment gateway and most developer-loved fintech API — was acquired by Stripe in 2020 and has adopted many of Stripe's API design conventions. Nigerian developers who learn Stripe's patterns (idempotency keys, webhook signature verification, payment intent lifecycle, connect architecture) will find this knowledge directly transferable when building on Paystack or other modern payment APIs. Diaspora and cross-border cases: Nigerian-founded companies incorporated in the United States, United Kingdom, or other Stripe-supported markets can register Stripe accounts under those foreign entities and use Stripe to charge international customers. This is a common path for Nigerian SaaS founders who incorporate in Delaware (for US market access or investor requirements) and use Stripe to charge global subscribers. The Nigerian individual may build and operate the product, but the contracting entity is foreign-incorporated. Stripe Connect is Stripe's marketplace and platform payment architecture, allowing a platform business to facilitate payments between buyers and sellers or service providers with automatic split payment, commission deduction, and payout management. For Nigerian developers building marketplace products intended for international markets — freelance platforms, services marketplaces, SaaS reseller programs — Stripe Connect provides the payment infrastructure to handle multi-party money flows between international participants. Stripe Billing handles subscription management, recurring payment scheduling, proration for mid-cycle plan changes, invoice generation, retry logic for failed payments, and metered billing for usage-based pricing. For SaaS products serving international markets, Stripe Billing reduces subscription payment infrastructure development from months to days while handling edge cases like payment method expiration, card declines, and dunning flows automatically. Stripe Radar is an AI-powered fraud detection system that scores every payment request in real time and can automatically block suspicious transactions based on customizable rules. For platforms handling international transactions that include potentially high-fraud regions or payment patterns, Radar provides machine learning-based fraud prevention without building custom fraud detection infrastructure. Stripe's documentation is widely considered the best in the payments industry — comprehensive, accurate, with full API reference, extensive guides for common integration patterns, and code examples in multiple languages. Nigerian developers studying payment API design use Stripe documentation as a reference model for understanding best practices in API design, error handling, webhook architecture, and payment security that apply across any payment provider.

124. Kuda Open API

Payments, Development Tools

Kuda Open API is the developer platform of Kuda Bank — Nigeria's first fully mobile-only bank, licensed by the Central Bank of Nigeria (CBN). Launched to enable businesses to embed banking infrastructure directly into their products, the Kuda Open API provides access to real Nigerian bank account infrastructure, NIP-powered instant transfers, dynamic virtual accounts, bill payments, and instant settlement capabilities — all through a clean RESTful API backed by one of Nigeria's most trusted and innovative financial institutions. Kuda Bank was founded in 2019 by Babs Ogundeyi and Musty Mustapha, and quickly grew into one of Nigeria's most popular neobanks, with millions of individual users. In 2022–2023, Kuda expanded its infrastructure to businesses through the Open API program, enabling companies to build financial products on top of its licensed banking rails — without needing their own CBN banking license. **What the Kuda Open API Does** The API is designed for businesses that need to move money programmatically within Nigeria. Key capabilities include: - **Bank Transfers**: Send NGN to any Nigerian bank account through the NIP (Nigeria Interbank Payment) system. Available as single transfers or bulk transfer batches, making it ideal for payroll, vendor payments, and mass disbursements. - **Dynamic Virtual Accounts**: Create unique Nigerian bank account numbers (tied to your Kuda business account) that customers can pay to. Payments trigger instant webhook notifications, enabling real-time payment confirmation without manual reconciliation. - **Single-use Account Numbers**: Generate one-time account numbers for specific payment purposes, reducing fraud and simplifying payment attribution. - **Instant Settlement**: Funds received can be settled in near real-time at 0.3% of the transaction value, capped at ₦100 — providing faster cash flow compared to traditional payment cycles. - **Account Verification**: Verify that a bank account name matches the account number before initiating a transfer — a critical fraud-prevention step for Nigerian fintech applications. - **Transaction History & Balances**: Query account balances and full transaction histories programmatically — essential for reconciliation, reporting, and financial dashboards. - **Bill Payments**: Purchase airtime, mobile data, cable TV subscriptions (DSTV, GOtv, Startimes), and electricity prepaid tokens via API, with commission opportunities on each transaction. **Authentication** The Kuda Open API uses API key authentication. Developers register on the Kuda Developer Portal (developer.kuda.com), complete business verification, and receive an API key that is passed as a Bearer token in the Authorization header of all API requests. The sandbox environment is accessible immediately after registration, with production access unlocked after KYB (Know Your Business) verification. **Sandbox Environment** Kuda provides a full sandbox environment that replicates all production capabilities. Developers can test transfers, create virtual accounts, simulate incoming payments, trigger webhook events, and validate account verification flows without moving real money. This makes it safe to develop and test integrations before going live. **Pricing** Kuda's pricing model is flat-fee per transaction — not percentage-based — which is a significant advantage for high-value transactions: - Transfers of ₦0–₦10,000: ₦12 per transaction - Transfers of ₦10,001–₦100,000: ₦10 per transaction - Transfers of ₦100,001–₦400,000: ₦9 per transaction - Transfers above ₦400,001: ₦7 per transaction - Instant settlement: 0.3% of transaction value, capped at ₦100 - Virtual account fee: 0.1% of transaction value (approximately) - No hidden fees — the listed prices are the final prices paid. This flat-fee structure means that a ₦1,000,000 transfer costs exactly ₦7, compared to percentage-based gateways that might charge ₦15,000 for the same transaction. **Nigeria Access & Requirements** To access production APIs, businesses must complete KYB (Know Your Business) verification, which requires: a CAC Certificate of Incorporation or Business Name Registration, BVN and government-issued ID for directors, and an active Nigerian business bank account. Sandbox access requires only registration — no documents needed. **Compliance & Regulatory Standing** Kuda Bank holds a Microfinance Bank licence from the CBN. The Open API inherits this regulatory standing, meaning virtual accounts and transfers executed through the API are backed by a licensed Nigerian financial institution. This is a significant compliance advantage for fintech builders who need to demonstrate regulated banking infrastructure to enterprise clients or regulators. **Challenges & Considerations** While Kuda's pricing model is excellent for high-value transfers, the ₦12 flat fee per low-value transfer can be proportionally high for very small transactions (e.g., ₦12 fee on a ₦100 transfer = 12%). Card payment acceptance is not currently part of the Open API — businesses needing card-based collection still require an additional payment gateway like Paystack or Flutterwave. International transfers and multi-currency account support are also not available. **Frequently Asked Questions** Q: Do I need a CBN license to use the Kuda Open API? A: No. Kuda's CBN Microfinance Bank license covers the banking infrastructure, so your business can offer account and transfer products without obtaining a separate license. Q: Can I use the sandbox without submitting documents? A: Yes. Sandbox registration requires only an email and business details. Full KYB documents are only required before going live. Q: Does Kuda support card payments through the Open API? A: No. The Kuda Open API is focused on bank transfers and virtual accounts, not card acceptance. Q: How fast are NIP transfers? A: NIP transfers are typically instant (within seconds) during normal operating hours. Q: Is Kuda Open API available to businesses outside Nigeria? A: The API is primarily designed for Nigerian-registered businesses. International companies may face restrictions on KYB verification.

125. Crypto APIs

Blockchain, Trading & Currency Exchange

Crypto APIs is a comprehensive blockchain infrastructure platform providing REST API access to over 20 blockchain networks through a single integration, with a unified endpoint structure that covers blockchain data, wallet management, address monitoring, NFT data, token information, mempool monitoring, and market data. For Nigerian developers who need coverage of multiple chains — Bitcoin for savings, Ethereum for DeFi, Tron for cheap USDT transfers, BNB Chain for trading — Crypto APIs provides a one-stop solution that reduces integration complexity and development time significantly. Nigeria's crypto ecosystem is multi-chain by nature. Nigerian users route different activities through different chains based on transaction costs and speed: Bitcoin for large value transfers and savings, Tron TRC-20 for USDT because the fees are fractions of a cent, Ethereum for DeFi protocols, and BNB Chain for trading at lower gas costs than Ethereum. A Nigerian wallet or payment application serving real users must support this diversity. Without Crypto APIs, building multi-chain support means separate integrations, separate node providers, and separate documentation for every chain. Crypto APIs unifies everything. The Blockchain Data module provides address information, transaction details, and block data for all supported chains. For Bitcoin (and other UTXO chains), this includes UTXO sets, inputs, outputs, and confirmation counts. For Ethereum and EVM chains, this includes internal transactions, event logs, and contract data. The endpoint structure is consistent — the chain name appears in the URL path, but the request/response format is the same — making multi-chain development straightforward. HD (Hierarchical Deterministic) Wallet management covers the full lifecycle: create an HD wallet with a master key, generate receiving addresses, sync the wallet to discover used addresses and balances, and build transactions. Crypto APIs handles all the chain-specific derivation path details, ensuring compatibility with standard wallet specifications. For Nigerian fintech companies building custodial or semi-custodial wallets, this provides a managed wallet infrastructure without the complexity of implementing BIP32/BIP44 from scratch. Address monitoring and webhooks allow subscribing to blockchain events on specific addresses. When a monitored address receives a transaction — whether in the mempool (unconfirmed) or in a confirmed block — Crypto APIs delivers an HTTP webhook notification to the configured endpoint. For Nigerian payment processors and exchanges, this event-driven architecture replaces inefficient polling loops and provides near-real-time payment detection. Webhook events include new incoming transactions, confirmed transactions, and double-spend alerts. NFT data endpoints return metadata, ownership history, and transfer events for ERC-721 and ERC-1155 tokens on Ethereum and other EVM chains. Nigerian NFT platforms can query NFT ownership without building their own indexing infrastructure. Token information endpoints return ERC-20 and BEP-20 token details including name, symbol, decimals, total supply, and holder counts. Mempool monitoring provides visibility into unconfirmed transactions — useful for Nigerian applications that need to detect incoming payments before block confirmation, estimate fee rates for outgoing transactions, or monitor for double-spend attempts on high-value incoming payments. Market data endpoints return current and historical prices for thousands of cryptocurrencies against fiat currencies including USD and, for select providers, NGN. Exchange rates between crypto pairs are available for fee calculation and display purposes. The free tier provides 10,000 credits per month — sufficient for prototyping and low-traffic applications. The Startup plan at $49/month (100,000 credits) serves small Nigerian startups, while the Business plan at $149/month handles production traffic. Enterprise plans with custom SLAs are available for established Nigerian exchanges and financial institutions.

128. Nomba Global Payout API

Development Tools, Payments, Trading & Currency Exchange

The Nomba Global Payout API is a cross-border payment disbursement product launched by Nomba in March 2026, designed specifically for Nigerian payment operators, remittance platforms, and fintechs that need to collect Naira or stablecoin funds from Nigerian users and disburse to recipients in international markets. It eliminates the need for operators to manually source foreign exchange or maintain multi-currency liquidity pools across different countries. Nomba is a CBN-licensed Nigerian Payment Service Provider. The Global Payout API represents a significant expansion of Nomba's capabilities beyond domestic Nigerian payments into the cross-border remittance corridor, addressing one of the most operationally complex challenges facing Nigerian fintech operators: access to affordable, reliable FX and settlement infrastructure for international disbursements. The API enables operators to collect funds in two ways: via NGN virtual accounts (where Nigerian senders transfer Naira) or via stablecoin deposits (USDT or USDC). Once funds are received, Nomba automatically converts them to the target currency and routes the disbursement through the appropriate local payment rail in the destination country. This auto-conversion capability is a critical differentiator — operators do not need to hold USD, GBP, EUR, or CAD reserves; Nomba handles the full FX lifecycle. Supported corridors at launch include: United Kingdom via Faster Payments (transfers up to £1,000,000, settled in 1–3 hours), European Union via SEPA transfer (up to €100,000, settled in under 1 hour), Canada via Interac (instant) and standard bank transfer, and the Democratic Republic of Congo via Mobile Money (instant) and bank transfer. Additional corridors are expected to expand over time. The developer integration flow involves four main steps. First, call the exchange rates endpoint to get the current NGN-to-destination-currency rate. Optionally use the Convert Money endpoint to lock this rate before initiating the transfer. Then call the payment methods endpoint for the destination country to retrieve available rails and required recipient details (bank account type, purpose of payment, etc.). Finally, authorize the transfer with the recipient's bank details and monitor the transaction status via the returned transaction ID. Authentication uses OAuth2 Bearer Tokens, consistent with Nomba's main API. Developers use either Client Credentials (for server-to-server) or PKCE flow (for mobile apps). Webhooks deliver real-time status updates for each disbursement, enabling operators to update their internal systems when a transfer succeeds or fails. Pricing for the Global Payout API is not publicly published. Nomba charges transaction-based fees for each corridor; operators are advised to contact Nomba's team for enterprise pricing based on expected monthly volumes. Given that the product targets high-volume remittance operators and fintechs, volume discounts are likely available. The Global Payout API is particularly significant for the Nigerian diaspora remittance market. Nigeria receives over $20 billion per year in remittances and is Africa's largest remittance destination. By enabling Nigerian-licensed platforms to send money OUT of Nigeria via a single API, Nomba addresses the reverse corridor — outbound from Nigeria — which is critical for freelancer payments, business vendor payments, and capital repatriation. From a compliance standpoint, all cross-border disbursements via Nomba are processed within the CBN's regulatory framework. Nomba holds the necessary licenses for international money transfer operations. For high-volume corridors, operators may be required to provide AML documentation and demonstrate the nature of their disbursement use case. Frequently Asked Questions: Which countries can I disburse to? At launch in March 2026: UK, EU, Canada, and DRC. Additional corridors are planned. Contact Nomba for the latest corridor list. Can I collect from Nigerian users in NGN? Yes — Nomba provides NGN virtual accounts for collection. The collected Naira is automatically converted to the destination currency at the prevailing rate. Can I lock the FX rate before initiating a transfer? Yes — use the Convert Money endpoint to lock the exchange rate before authorizing the disbursement. This protects against rate fluctuations between quoting and execution. Is this separate from Nomba's domestic API? Yes — the Global Payout API is a distinct product with its own documentation at developer.nomba.com/docs/products/global-payout/introduction. Domestic Nigerian payments use the main Nomba Checkout and Transfer APIs.

129. Quidax

Blockchain, Development Tools, Trading & Currency Exchange

Quidax is Nigeria's first Securities and Exchange Commission (SEC)-licensed cryptocurrency exchange, founded in 2018 by Buchi Okoro. The SEC provisional license, obtained in 2024, authorizes Quidax to operate as a Digital Assets Exchange — allowing it to collaborate with Nigerian banks and financial institutions, and offer institutional-grade API access to businesses building crypto-enabled products. Quidax has further deepened its infrastructure play by partnering with Lisk, an Ethereum Layer-2 blockchain optimized for Africa, to build DeFi rails connecting Quidax's NGN liquidity with on-chain applications. The Quidax Developer API (developer.quidax.com) is designed for businesses — not just retail traders — who want to embed cryptocurrency services into their products. The API enables fintechs, e-commerce platforms, and financial applications to integrate crypto buying, selling, holding, and payment acceptance without building exchange infrastructure from scratch. Quidax boasts a 99.8% uptime SLA backed by multi-region infrastructure, making it suitable for production-grade business integrations. Authentication is via Bearer Token (API Key) obtained from the Quidax account dashboard. Requests are made over HTTPS with JSON payloads. Quidax provides webhook notifications for transaction events including order fills, deposits, and withdrawals. One of the most commercially interesting features for Nigerian developers is stablecoin payment acceptance. Businesses can configure Quidax to accept USDT (Tether) or USDC (USD Coin) from customers and automatically receive NGN settlement in their business account. This eliminates the need for merchants to manage cryptocurrency volatility while offering customers the option to pay with stablecoins — a payment rail popular with Nigerian diaspora and crypto-native consumers. Quidax supports multiple digital assets including Bitcoin (BTC), Ethereum (ETH), USDT, USDC, and other tokens listed on the exchange. The crypto trading API allows platforms to execute market and limit orders, query order books, access price feeds, manage wallets, and retrieve transaction history programmatically. The Lisk partnership announced in 2026 opens Quidax's liquidity to DeFi protocols on the Lisk network. Developers building DeFi applications on Lisk can access Quidax's Nigerian NGN/crypto liquidity pools — creating Africa's first DeFi infrastructure with Nigerian naira integration. This positions Quidax at the intersection of centralized exchange liquidity and DeFi composability. From a regulatory standpoint, Quidax's SEC Digital Assets Exchange license is the most comprehensive crypto regulatory approval in Nigeria. The SEC license permits institutional partnerships with banks, which is not available to unlicensed crypto platforms. This creates significant competitive advantages for developers building crypto products that require banking integration or institutional KYC. All users and businesses accessing the Quidax API must complete KYC verification as required by the Nigerian SEC and SCUML (Special Control Unit Against Money Laundering). For businesses embedding Quidax APIs, compliance documentation for the business entity is required during onboarding. Known challenges: The Quidax API is more focused on exchange functionality than payment gateway use cases. For pure payment acceptance without crypto trading, developers may find the API overhead higher than using stablecoin-native payment APIs. Additionally, the regulatory landscape for crypto in Nigeria continues to evolve, which may affect permitted use cases. Frequently Asked Questions: Is Quidax the only SEC-licensed crypto exchange in Nigeria? Quidax was the first to receive the provisional SEC Digital Assets Exchange license in Nigeria (2024). Other exchanges are applying for licenses under the same framework. Can I use Quidax to accept Bitcoin payments on my website? Yes — but Quidax also provides stablecoin (USDT/USDC) payment acceptance which protects merchants from Bitcoin price volatility while still accepting crypto. Does Quidax support NGN withdrawal to bank accounts? Yes — businesses receive NGN settlement to their Nigerian bank accounts for accepted crypto payments.

This extensive multi-country licensing makes Payaza one of the most geographically diverse African payment platforms available to developers — a single Payaza API integration can power both local Nigerian payments and international collections from the UK, Canada, and the UAE. Payaza's developer documentation is available at docs.payaza.africa, with integration support at payaza.africa/integration-support. The API is RESTful with JSON payloads. Authentication uses a Bearer Token (Secret Key from the Payaza merchant dashboard). The API design follows standard patterns familiar to developers who have used Paystack or Flutterwave. Payaza supports card payments (Visa, Mastercard, Verve), bank transfer checkout, and mobile money across its supported markets. In Nigeria specifically, the gateway supports local debit card transactions, bank transfer collections, and outbound payouts to Nigerian bank accounts. In West Africa, mobile money is supported via integration with MTN Mobile Money, Orange Money, and other providers. For UK and international merchants, Payaza's local acquiring licenses enable card acceptance in British pounds and other major currencies. Multi-currency support is a primary differentiator. Merchants can configure Payaza to accept payments in NGN, GBP, USD, CAD, EUR, KES, GHS, and other currencies depending on their licensed market. This is particularly valuable for Nigerian diaspora businesses, e-commerce platforms with international customers, and SaaS companies billing customers globally. Payaza offers fast local and international payouts. For Nigerian businesses, payouts to local bank accounts are processed within standard Nigerian interbank timelines. For international payouts, Payaza's licenses in the UK, US, and Canada enable direct disbursement to foreign bank accounts without the complexity of SWIFT correspondent banking. The platform is built with security and compliance at its core. Payaza holds investment-grade security certifications and is PCI-DSS compliant. The platform has been described as offering "the most enjoyable payment experience" by Nigerian SME users, reflecting a focus on clean UI, fast onboarding, and responsive merchant support. Payaza has a particular strength in the creator economy and SME segment. Nigerian freelancers, digital product sellers, and content creators use Payaza to collect international card payments from overseas clients and receive settlement in their Nigerian accounts. The payment link feature requires no coding — making it accessible to non-technical merchants. Exact pricing is not publicly published on the Payaza website. Transaction fees are approximately 1.4–1.5% for local Nigerian transactions plus applicable flat fees, with international rates higher. Merchants are advised to contact Payaza directly for current rates based on their expected transaction volume and geography. The Payaza sandbox environment is available for testing. Moving from sandbox to live requires completing KYC onboarding including CAC registration, director BVN and government ID, and a business bank account. For international markets, Payaza may request additional compliance documentation depending on the country. From a compliance standpoint, Payaza Africa Limited is licensed by the CBN in Nigeria and has equivalent regulatory approvals in each of its 16+ operating jurisdictions. The breadth of licenses is a significant competitive advantage that took years to accumulate and represents a high barrier to entry for competitors. Frequently Asked Questions: How many countries does Payaza support? Payaza is licensed in 16+ countries as of 2026, including Nigeria, Ghana, Kenya, UK, US, Canada, and UAE. Additional markets are being added. Does Payaza support USD and GBP collection?
