  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.
