1 Best APIs for 25+ Crypto Pairs in Nigeria

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.
