Coin Metrics is a Boston-based crypto financial intelligence provider founded in 2017, selling institutional-grade cryptoasset network (on-chain) data, exchange market data (trades, quotes, order books, candles, derivatives), CMBI indexes, reference rates, and reference/security-master data. Everything is delivered through a single documented API v4 - REST at api.coinmetrics.io/v4 and WebSocket streaming at wss://api.coinmetrics.io/v4 as paid, API-key products - plus a free, keyless Community API at community-api.coinmetrics.io/v4 under a CC BY-NC 4.0 license, with flat files, Python and R clients, and Google Sheets as additional delivery channels. A complete OpenAPI 3.0.2 definition is published on the docs site. Coin Metrics is now part of Talos: coinmetrics.io 301-redirects to talos.com/our-solutions/data/overview, while docs.coinmetrics.io and the api/community-api hosts remain live under the Coin Metrics brand.
