CoinAPI is a financial data and execution platform delivering normalized real-time and historical cryptocurrency market data and trade execution across more than 350 exchanges. Its product family covers a Market Data API (REST, WebSocket, FIX, and flat-file S3 delivery) for trades, quotes, order books, OHLCV, exchange rates, and derivatives metrics; an EMS Trading API (Execution Management System) that lets users place, manage, and route orders across multiple venues through one normalized REST/WebSocket/FIX interface; and Index and Metrics APIs that aggregate cross-exchange data into reference indexes and risk metrics. FIX endpoints (fix.coinapi.io) use GeoDNS to route to the nearest datacenter for low-latency connectivity.
