NGN Market API

NGN Market API

NGN Market API provides access to Nigerian financial market data including stock prices, foreign exchange rates, and market indices. The API enables developers to build financial applications with real-time and historical Nigerian market data. Nigerian fintech platforms, traders, and investment applications use NGN Market API to integrate naira-denominated market data and forex rates into their systems.

Exchangerate.host

Exchangerate.host

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.

Trove Finance API

Trove Finance API

Trove Finance is a Nigerian investment and wealth management platform providing access to African financial market data. The Trove Finance API enables developers to integrate African stock market data, forex rates, commodity prices, and investment portfolio tools into applications. Nigerian fintech platforms, investment advisors, and trading applications use Trove Finance API to provide real-time African market data and investment analytics to Nigerian investors.

ExchangeRate-API

ExchangeRate-API

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.

FastForex

FastForex

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.

Frankfurter

Frankfurter

Frankfurter is a free, open-source currency exchange rates API built on top of official European Central Bank reference exchange rate data. The project delivers ECB foreign exchange rates through a clean, modern REST API with no registration requirement, no API key, and no rate limits documented — offering a completely frictionless entry point for developers who need reliable currency conversion data powered by one of the world most authoritative central bank rate sources. The European Central Bank publishes official reference exchange rates for 32 currencies against the Euro on each business day at approximately 16:00 CET. These reference rates are computed from the aggregate of market rates reported by financial institutions across the eurozone, making them the official benchmark for euro currency conversions in European financial reporting and compliance contexts. Frankfurter exposes these ECB rates through a straightforward REST API that makes accessing them as simple as an HTTP GET request. The latest rates endpoint returns the most recently published ECB exchange rate set for all supported currencies relative to any specified base currency. By default, rates are base EUR, but any supported currency can be used as the base by specifying it in the request parameter. This flexibility allows applications to retrieve NGN/USD, EUR/GBP, or any other combination without client-side conversion math. The response is a clean JSON object with ISO 4217 currency codes as keys and decimal rate values. Historical rates are accessible for any date from January 4, 1999, when the ECB began publishing its reference rates, through the present. This exceptional historical depth of over 25 years of official ECB rates supports the most demanding historical analysis use cases. Nigerian financial researchers studying the long-term trajectory of major currencies, academics modeling currency relationships, or developers building historical FX analysis tools for Nigerian businesses with international exposure can query any specific date or date range within this extensive archive. Time series queries retrieve exchange rates across a date range in a single request, returning a day-by-day array of rate sets between the start and end dates. This is more efficient than making individual date queries for each day in a range and enables building currency trend charts, calculating moving averages, or analyzing rate volatility across specific periods of interest. A currency conversion endpoint simplifies the most common use case by accepting an amount, source currency, and target currency and returning the converted amount directly. This eliminates client-side conversion logic for applications where only the final converted value is needed. It is important to note that Frankfurter covers 32 currencies, and the Nigerian Naira is not among them. The ECB reference rate set covers major traded currencies primarily from developed markets. For applications specifically needing NGN exchange rates, a dedicated currency API with NGN support would be more appropriate. However, for Nigerian businesses primarily working with EUR, USD, GBP, CHF, JPY, and other major ECB-covered currencies, Frankfurter provides official-quality rate data at zero cost. The open-source nature of Frankfurter means the complete server-side codebase is publicly available. Organizations requiring guaranteed availability, data sovereignty, or control over the rate data pipeline can self-host Frankfurter on their own infrastructure, fetching directly from the ECB and serving through their own API endpoint. This self-hosting option is particularly relevant for Nigerian financial institutions subject to regulatory requirements about external data dependencies. For Nigerian developers building personal finance tools, business productivity applications, or learning projects involving international currency handling, Frankfurter offers immediate, zero-cost access to authoritative exchange rate data that is suitable for display and educational purposes without the overhead of account management.

FxRatesAPI

FxRatesAPI

FxRatesAPI is a foreign exchange rate data provider offering real-time, historical, and time-series exchange rate data for over 180 currencies through a clean REST API. The service aggregates rates from multiple financial data sources and delivers accurate exchange rates for currency conversion, price display, accounting, and financial analytics applications. For Nigerian developers and businesses building applications that deal with multiple currencies — which describes the majority of Nigerian fintech, e-commerce, and accounting software — FxRatesAPI provides reliable NGN currency data alongside all major global currencies. Nigeria's position as Africa's largest economy means that currency exchange rates are not just a technical feature — they are a core business concern. The USD/NGN exchange rate directly affects the cost of imported goods displayed on Nigerian e-commerce platforms, the naira value of remittances sent from Nigerians in the diaspora, the financial reporting of Nigerian companies with foreign currency revenues, and the investment decisions of Nigerians holding foreign currency assets. An accurate, current USD/NGN rate, updated at least daily, is a fundamental requirement for dozens of categories of Nigerian applications. The /latest endpoint returns current exchange rates for all 180+ supported currencies from a specified base currency. To get the current USD/NGN rate, a Nigerian application calls the endpoint with base=USD and receives the NGN rate in the response. The same call returns rates for EUR, GBP, JPY, and every other supported currency simultaneously — making it straightforward to build multi-currency displays that show prices in multiple currencies at once. The /convert endpoint handles currency conversion arithmetic — pass the amount, the source currency, and the target currency, and FxRatesAPI returns the converted amount at the current rate. For Nigerian e-commerce platforms that need to convert a product price from USD to NGN for display, this eliminates client-side conversion code and ensures the rate used is always current. Historical exchange rate data is available via the /historical endpoint, returning rates for any past date. This is critical for Nigerian accounting and ERP applications that need to record transactions at the exchange rate on the transaction date — a requirement for Nigerian financial reporting that must comply with both IFRS standards and FIRS (Federal Inland Revenue Service) guidelines on foreign currency transactions. The /timeseries endpoint returns exchange rate data over a range of dates with daily resolution, enabling trend analysis and charting. For Nigerian currency analytics tools, this data powers time-series charts showing the USD/NGN rate history — valuable context for Nigerians trying to understand naira depreciation trends and optimize their currency holding decisions. Fluctuation data via the /fluctuation endpoint shows the change in exchange rates over a specified period — useful for Nigerian fintech apps that want to display "the naira weakened 2.3% against the dollar this week" type of contextual information alongside current rates. The free plan provides 1,500 requests per month with daily rate resolution — sufficient for low-traffic applications where real-time rates are not critical. For applications needing hourly or minute-level rate updates (forex comparison tools, live price displays on high-traffic Nigerian e-commerce sites), the Basic plan at $9.99/month provides up to 100,000 requests and hourly resolution. The Professional plan at $29.99/month provides minute-level resolution and up to 1 million requests per month — appropriate for Nigerian fintech applications with significant user traffic. All endpoints accept a simple api_key query parameter with no request signing required, making FxRatesAPI one of the quickest currency data integrations available for Nigerian developers. Responses are JSON by default with XML available as an alternative format.

CurrencyFreaks

CurrencyFreaks

CurrencyFreaks is a foreign exchange rate API providing real-time and historical currency data for over 150 global currencies, with particular value for Nigerian developers and businesses needing reliable Naira exchange rate data. The service aggregates rates from multiple financial data sources to deliver accurate mid-market rates with consistent uptime, making it a dependable choice for fintech applications, payment systems, and currency-aware business software. The API delivers current exchange rates across all supported currency pairs, with rates refreshed regularly throughout the trading day to track market movements. For applications where currency rate freshness matters — such as payment processing, order pricing, or customer-facing currency displays — CurrencyFreaks provides the up-to-date data needed to reflect actual market conditions rather than stale approximations. The Nigerian Naira is among the supported currencies, ensuring NGN/USD, NGN/EUR, NGN/GBP, and other critical Naira pairs are available for Nigerian applications. Historical exchange rate data is available from 2000 onwards, giving developers access to over two decades of FX rate history. This extensive archive is valuable for multiple use cases: financial modeling that requires long-term currency trend analysis, accounting systems that need to reconstruct historical transaction values at the exchange rates prevailing at the time of each transaction, and research applications analyzing the relationship between currency movements and economic events in Nigeria and globally. The historical depth is particularly significant for Nigerian context. The Naira has experienced several major devaluation episodes since 2000, including the 2016 exchange rate liberalization, the 2023 unification of official and parallel market rates, and subsequent volatility. Applications built for Nigerian financial analysis, research, or compliance can access the complete historical rate record through CurrencyFreaks to accurately model and document the impact of these exchange rate changes on business performance or asset values. Currency conversion is directly supported through a dedicated convert endpoint. Rather than retrieving raw rates and performing conversion on the client side, applications can submit a source currency, target currency, and amount and receive back the converted value. This simplifies integration for applications where only conversion functionality is needed, such as product pricing widgets, invoice currency selectors, or quick calculator features. For Nigerian e-commerce platforms running multicurrency storefronts, CurrencyFreaks enables automatic price adjustment in multiple currencies based on live rates. When a Nigerian business displays prices in USD for international customers or in GBP for diaspora buyers, using live rates ensures the foreign currency price accurately reflects the current Naira equivalent, protecting the business from pricing errors due to rate movements. Remittance service providers and mobile money platforms operating in Nigeria rely on accurate FX data to calculate and display the Naira amount recipients will receive. Compliance and transparency requirements in the Nigerian financial services sector mean that displayed rates must be accurate and traceable. CurrencyFreaks provides the rate data foundation while applications handle the display and audit trail requirements. The API uses simple API key authentication included in request query parameters or headers. The JSON response format is clean and consistent, with currency codes following ISO 4217 standards for interoperability. The free plan provides 1,000 monthly requests — sufficient for development, testing, and low-traffic applications — while paid plans scale up request limits to accommodate production workloads. Nigerian developers benefit from a straightforward onboarding process requiring only email registration to obtain a working API key.

Alpha Vantage

Alpha Vantage

Alpha Vantage is a comprehensive financial data API covering US stocks, ETFs, mutual funds, forex exchange rates, cryptocurrencies, commodities, and economic indicators — all accessible through a single, consistent REST API with a generous free tier. The platform is particularly notable for its extensive library of over 50 pre-calculated technical indicators (RSI, MACD, Bollinger Bands, EMA, SMA, and many more), which are available as first-class API endpoints rather than requiring developers to compute them from raw price data. For financial application developers and quantitative analysts, Alpha Vantage provides a rich data foundation that spans traditional finance and crypto in a single integration. Nigerian developers should be aware of an important context distinction: Alpha Vantage's API key and data endpoints are accessible from Nigeria without geographic restrictions, and the forex and cryptocurrency data are fully usable for Nigerian applications. However, Alpha Vantage is primarily oriented toward US stock market data — NYSE and NASDAQ-listed companies, US ETFs, and US economic indicators. Nigerian Stock Exchange (NGX) listed stocks are not covered. The ng_support=false designation reflects that the primary use case (US equities) does not serve Nigerian users, not that the API itself is blocked. Nigerian developers building forex tools, crypto analytics, and global market data applications can use Alpha Vantage productively. The Forex (FX) module provides exchange rate data for 180+ currency pairs including USD/NGN, EUR/NGN, GBP/NGN, and all major cross-currency combinations. The FX_DAILY endpoint returns daily OHLCV (open, high, low, close, volume) data going back 20+ years for any forex pair — enabling Nigerian developers to build long-term trend charts showing the USD/NGN rate history. FX_INTRADAY provides intraday data at 1-minute, 5-minute, 15-minute, 30-minute, and 60-minute intervals, enabling high-frequency forex rate displays for Nigerian trading platforms. The Cryptocurrency module covers Bitcoin, Ethereum, and hundreds of altcoins with DIGITAL_CURRENCY_DAILY, DIGITAL_CURRENCY_WEEKLY, and DIGITAL_CURRENCY_MONTHLY endpoints. Each crypto data point includes both the USD value and the value in a specified market currency — Nigerian developers can request BTC/USD data with NGN conversion included in every response, enabling portfolio tracking applications that display crypto values directly in naira. Technical Indicators are Alpha Vantage's most distinctive feature. Rather than fetching raw OHLCV data and computing indicators client-side, Nigerian developers can call endpoints like GET /query?function=RSI&symbol=BTC&interval=daily to receive pre-calculated RSI values going back years. The 50+ available indicators cover trend-following (EMA, SMA, WMA, DEMA, TEMA), momentum (RSI, MACD, STOCH, CCI, MOM, ROC), volatility (BBANDS, ATR), and volume indicators. For Nigerian quantitative developers building algorithmic trading systems or analysis tools, this eliminates significant computational overhead. The Economic Indicators module covers US macroeconomic data: Federal Reserve interest rates, CPI inflation, unemployment, GDP, and treasury yields. While these are US-focused metrics, they are globally relevant — Nigerian investors and analysts closely track US Fed rate decisions because they directly affect global capital flows, dollar strength, and by extension NGN/USD exchange rates. The News & Sentiment endpoint returns financial news articles with AI-generated sentiment scores for specific stocks, sectors, or forex pairs. Nigerian financial analysts building market research tools can use this endpoint to track sentiment around USD/NGN, US equities held by Nigerian investors, or cryptocurrency markets. The free tier provides 25 requests per day and 500 per month — sufficient for learning the API and building prototypes. Premium plans starting at $50/month (75 requests per minute) support production applications. No credit card is required for the free tier, making it accessible to Nigerian developers exploring the platform without financial commitment.

Currency-api

Currency-api

Currency-api is a free, open-source currency exchange rates API that provides daily exchange rate data for over 160 currencies with absolutely no authentication, registration, or API key required. Maintained as a community project and hosted on GitHub, the API serves as a zero-friction starting point for developers who need basic currency conversion capabilities without the overhead of account creation, key management, or usage billing. The API works by fetching exchange rate data from public financial sources and exposing it through simple, predictable REST endpoints. To retrieve the current rate between any two currencies, developers simply make an HTTP GET request to the endpoint with the base currency code and target currency code. The response is a clean JSON object containing the exchange rate, making it immediately usable in web, mobile, and server-side applications with minimal parsing overhead. Historical rates are accessible by specifying a date in the request URL, allowing developers to retrieve the exchange rate that was in effect on any past date. This backward-looking capability is important for applications that process historical financial data — accounting tools that record the Naira value of foreign currency transactions on the date they occurred, analytics platforms that analyze currency trends over time, or audit systems that need to reconstruct historical valuations. The Nigerian Naira is supported alongside all other major and many minor global currencies. For Nigerian developers building their first currency-aware feature — perhaps adding a price converter to a personal project, building a simple FX calculator, or creating a proof-of-concept for a fintech application — Currency-api removes every barrier to entry. There are no API keys to request, no credit card to enter, no signup forms to complete. The API simply works. For professional and production applications, the lack of an SLA and the absence of rate limit documentation means Currency-api is most suitable as a development tool or for low-traffic applications where occasional downtime would not cause serious harm. Nigerian startups building MVPs and prototypes benefit from being able to test currency features without committing to a paid service, then migrating to a more robust commercial API when the application reaches production scale. The open-source nature of Currency-api means that developers who need guaranteed uptime can self-host the entire infrastructure. The project repository on GitHub includes all code needed to run the data collection and API serving components, giving technically capable Nigerian teams the option to deploy their own instance on cloud infrastructure they control. This eliminates dependency on a third-party service and removes concerns about rate limits or service discontinuation for mission-critical applications. Because no API key is required, Currency-api is particularly useful in educational settings. Nigerian university courses covering web development, fintech application building, and API integration can use Currency-api as a teaching example without requiring students to create accounts or manage credentials. The simplicity of the API makes it an ideal first REST API integration exercise for coding bootcamp students and self-taught developers across Nigeria. The API is accessed via simple GET requests with currency codes as path parameters. Responses follow a consistent JSON structure across all endpoints, making it easy to understand and integrate quickly. The GitHub project README provides clear documentation with example requests covering all supported use cases. For Nigerian freelancers and independent developers building client projects where budget constraints are a real consideration, Currency-api provides genuine production value for simple currency display features without any ongoing cost. Combined with a caching layer on the application side to avoid excessive requests to the free service, Currency-api can power reliable currency displays for Nigerian websites and apps serving audiences that need to see prices in multiple currencies.

1Forge

1Forge

1Forge is a forex data API that specializes in real-time tick-level currency exchange rates with bid/ask spread data and WebSocket streaming. Unlike basic exchange rate APIs that provide a single mid-rate updated daily or hourly, 1Forge provides the actual bid and ask prices as quoted in the interbank forex market — the same spread-aware pricing that forex brokers and trading platforms use. For Nigerian fintech applications and trading platforms that need to display forex rates with the precision and real-time responsiveness of a live trading environment, 1Forge is one of the most appropriate forex data providers available. Nigeria's forex market is significant and multifaceted. The Central Bank of Nigeria (CBN) sets official exchange rates, while unofficial and parallel market rates often differ substantially. Nigerian forex trading platforms, remittance services, bureau de change operators, and cross-border payment companies all need access to real-time international interbank forex rates as a benchmark — both for pricing and for compliance purposes. 1Forge provides interbank-sourced rates for over 700 currency pairs, including USD/NGN, EUR/NGN, GBP/NGN, and all major cross-currency pairs relevant to Nigerian businesses. The /quotes endpoint is the core data endpoint, returning current bid and ask prices for specified currency pairs. The bid price is what a buyer will pay (the lower price), and the ask price is what a seller receives (the higher price). The spread — the difference between bid and ask — represents market liquidity and transaction cost. For Nigerian forex trading platforms displaying rates to retail traders, providing bid/ask data rather than just a mid-rate gives a more honest representation of the actual cost of a currency transaction. The /convert endpoint accepts an amount, a from-currency, and a to-currency, returning the converted amount at the current rate. This is the simplest integration point for Nigerian applications that need currency conversion — e-commerce platforms displaying prices in multiple currencies, invoice tools converting NGN amounts to USD equivalents, or payment apps showing users the expected exchange at checkout. WebSocket streaming is 1Forge's premium feature for applications requiring continuous real-time rate updates. Instead of polling the REST API every few seconds, the WebSocket connection delivers push notifications whenever a price changes — enabling rate displays that update in real time without polling overhead. For Nigerian live forex rate tickers, remittance cost calculators that show real-time rate changes, and trading platform price feeds, WebSocket streaming provides a significantly better user experience than polling. The /market_status endpoint indicates whether the forex market is currently open or closed. The global forex market operates 24 hours a day on weekdays, but is closed on weekends. For Nigerian applications that display forex rates or accept forex transactions, knowing whether the market is currently active is important context — rates during market hours are live and rapidly changing, while weekend rates may be stale from Friday's close. The free plan provides 1,000 requests per day but limits access to 8 currency pairs — sufficient for prototyping and applications focused on a small number of specific pairs. The Developer plan at $39/month expands to 5,000 requests per day and full pair coverage. The Professional plan at $79/month provides 20,000 requests per day, suitable for higher-traffic Nigerian fintech applications. Enterprise pricing is available for high-frequency or high-volume use cases. 1Forge's API key authentication is straightforward — no request signing required, just include the api_key parameter in REST requests or the WebSocket connection URL. This simplicity makes integration quick for Nigerian developers, with most integrations completable in a few hours of development time.
