CoinCap.io: The Top-Ranked Cryptocurrency API for Real-Time Market Data
CoinCap.io is a crypto listings website with key information and metrics about different crypto assets. The API supports REST and WebSocket protocols and has been available since June 2015. It is easy to use, but missing some key information and pricing can be incorrect. Other APIs, such as Binance and CoinAPI, offer more metrics and better user reviews.
