6 Best APIs for Market data in Nigeria

Financial data and market intelligence API for Nigeria and Africa. Nairametrics provides APIs for accessing financial news, market data, and economic indicators. Enables developers and businesses to build financial intelligence applications.

Finnhub is a financial market data API providing real-time and historical stock quotes, company fundamentals, earnings data, and alternative datasets (insider transactions, social sentiment, ESG scores) across global exchanges. It notably includes coverage of the Nigerian Exchange (NGX) alongside major US, European, and Asian markets, making it one of the few widely-used international market data providers with any direct Nigerian equities coverage. The core REST API exposes endpoints for real-time quotes, historical OHLCV candles, company profiles, financial statements (income statement, balance sheet, cash flow), analyst estimates, and earnings calendars. A WebSocket feed streams live trade-level price updates for supported exchanges, useful for building live tickers or algorithmic trading signals. Authentication uses a simple API key passed as a query parameter or header. The free tier allows 60 API calls per minute with access to a meaningful subset of endpoints (real-time US quotes, basic fundamentals), which is enough for prototyping a portfolio tracker or market dashboard. Paid plans unlock full historical depth, additional exchanges including NGX, and higher rate limits. For Nigerian fintech and investment platforms building portfolio trackers, robo-advisors, or market research tools, Finnhub is a practical way to get both global and NGX-adjacent market data from a single integration rather than stitching together multiple region-specific providers.

APIFarmer is a comprehensive farm management data API that provides an all-in-one programmatic backend for agricultural applications, delivering data services covering crop planning, farm record management, agronomic recommendations, market price data, and agricultural calendar management. The platform is designed as a developer infrastructure layer for agritech companies building farmer-facing applications, enabling developers to integrate professional farm management capabilities without building the underlying agricultural data systems from scratch. Farm record management through APIFarmer allows agricultural applications to store and retrieve structured data about farm operations: field boundaries, planting dates, crop varieties, input application records, irrigation events, pest and disease observations, and harvest records. This structured farm history is the foundation for both retrospective performance analysis — understanding why a field performed well or poorly in a given season — and prospective recommendations that use historical data to guide future season decisions. Agronomic recommendations from APIFarmer leverage crop science knowledge bases to deliver planting advice, nutrient management guidance, irrigation scheduling support, and pest and disease management recommendations to farmers through integrated agricultural apps. For Nigerian agritech developers who want their apps to provide agronomically sound advice without employing a team of agronomists to maintain recommendation content, APIFarmer's recommendation engine provides a scalable advisory content layer. Crop planning tools within APIFarmer help farmers and farm managers develop season plans that optimize resource allocation, crop mix selection, and input purchasing. For Nigerian commercial farmers managing multiple fields with different soil types, irrigation access, and market connections, structured crop planning tools that help optimize seasonal decisions across the farm portfolio have clear economic value. Market price integration within APIFarmer provides commodity price data relevant to Nigerian farmers' marketing decisions. Knowing current and historical prices for cassava, maize, rice, sorghum, tomatoes, and other major Nigerian farm products helps farmers make informed decisions about timing of sale, storage versus immediate market access, and crop selection for the next season based on price signals. Applications built on APIFarmer can surface this market intelligence at appropriate decision points in the farm management workflow. Agricultural calendar management helps Nigerian farmers track timing of critical operations within the production cycle — soil preparation, planting, fertilizer applications, spraying schedules, weeding, and harvest windows — with alerts and reminders delivered through the application. Managing a Nigerian farm seasonally involves dozens of timing-sensitive operations, and a digital calendar system backed by APIFarmer keeps farmers organized and reduces the risk of missing critical windows due to competing demands on attention. For Nigerian commercial farming operations managing multiple farms, employees, and equipment, APIFarmer's multi-farm management capabilities provide structured data organization that enables performance comparison across farms, employee task assignment and tracking, and portfolio-level reporting that farm managers and agricultural investors need for operational oversight. Integration with downstream agricultural supply chain systems — input suppliers, commodity aggregators, financial service providers — is enabled through APIFarmer's API infrastructure. An agritech platform built on APIFarmer can connect farm operational data to input purchasing workflows (when the farm record shows a fertilizer application is due, prompt the farmer to order), to commodity marketing platforms (when harvest is complete, connect to buyers), and to agricultural finance (use farm records as supporting documentation for loan applications). This end-to-end connectivity from farm management to market and finance positions APIFarmer as infrastructure for comprehensive agricultural platforms rather than a narrow point solution.

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.
