CryptoCompare
CryptoCompare's long-running market-data API — spot and derivatives prices, historical OHLCV, order books, and a well-known news feed spanning thousands of assets — was folded into CoinDesk Data after CoinDesk's 2023 acquisition of CryptoCompare; its old developer portal now redirects straight to developers.coindesk.com. Every endpoint requires an API key today, with a free tier for light use and metered paid plans for production traffic.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
