3 Best APIs for Stock Market in Nigeria

NGX Data Portal is the official market data API provided by the Nigerian Exchange Group (NGX) — Nigeria's primary securities exchange — giving developers, financial technology companies, investment platforms, and fintech startups access to real-time and historical equities data, market indices, trading statistics, and capital market information directly from the authoritative source. For Nigerian financial applications that need reliable, official stock market data, the NGX Data Portal is the most legally authoritative source available, directly supplying the data that underlies Nigeria's capital markets. Equities data from the NGX Data Portal covers all companies listed on the Nigerian Exchange, including those on the Main Board, Growth Board, and Alternative Securities Market (ASeM). For each listed company, the API provides current day trade data: last traded price, opening price, daily high and low, trading volume, total deal count, and market capitalization. This comprehensive intraday snapshot enables Nigerian investment apps to display accurate, current stock information to retail investors building their portfolios on Nigerian equities like Dangote Cement, MTN Nigeria, Zenith Bank, Access Holdings, and other major NGX-listed companies. The NGX All-Share Index (ASI) and sector indices are accessible through the portal, providing the benchmark indices against which Nigerian portfolio performance is typically measured. The ASI is Nigeria's headline stock market indicator, widely reported in Nigerian financial media and used by fund managers, institutional investors, and retail investors to gauge overall market direction. Sector indices — Banking, Insurance, Oil and Gas, Consumer Goods, Industrial — allow sector-level analysis for Nigerian investment platforms offering sector-focused portfolio tools or thematic investment recommendations. Historical price data through the NGX Data Portal enables backtesting of investment strategies, computing of long-run returns for NGX-listed stocks, analysis of historical volatility, and construction of financial models for Nigerian securities. Academic researchers at Nigerian universities, investment analysts at stockbroker firms, and quantitative finance professionals can use the historical data to build evidence-based investment research and analysis. End-of-day (EOD) data snapshots capture each trading day's final prices, volumes, and statistics for all listed securities, providing a daily record for tracking portfolio positions, computing daily returns, and maintaining a database of Nigerian securities prices. Wealth management platforms and portfolio tracking apps serving Nigerian investors need reliable EOD data to compute accurate daily portfolio valuations and track performance over time. Corporate actions data including dividends, rights issues, bonus issues, and stock splits is available through the NGX Data Portal, enabling investment apps to accurately adjust historical price series for corporate actions and show investors the true total return history of their holdings — accounting for cash dividends received and bonus shares credited over the holding period. The NGX Data Portal operates on a freemium model with a free tier for basic market data access and paid commercial licenses for real-time streaming data, higher request volumes, and redistribution rights. Nigerian regulated financial services businesses that publicly display NGX data in their platforms may need a formal data licensing agreement with NGX. Developers can register for a free API key on the NGX Data Portal developer section and begin accessing market data immediately for testing and development purposes.
