Implementation notes
When to use CryptoCompare
CryptoCompare provides 100,000 calls/month free — among the most generous in the crypto data category — with coverage including historical OHLCV, social stats (Reddit subscribers, Twitter followers), mining data, and exchange info. It is the best free option when you need social metrics alongside price data.
Common pitfalls
- CryptoCompare uses a tiered credit system. Calls to different endpoints consume different credit amounts — the `/data/price` endpoint costs 1 credit, while `/data/histoday` (historical OHLCV) costs 50+ credits depending on the `limit` parameter. Always check the credit cost table in the docs before designing your request pattern.
- The API key must be passed as an `Authorization: Apikey YOUR_KEY` header. Passing it as a query parameter (`api_key=YOUR_KEY`) also works but is deprecated and may stop working without notice.
- The free tier restricts WebSocket streaming to the Streamer API at `wss://streamer.cryptocompare.com/v2` but limits concurrent connections to 1. If your app opens multiple WebSocket connections, subsequent ones receive an error without a clear message about the connection limit.
- Social stats data (`/data/social/coin/latest`) is often stale by several hours for low-cap coins. CryptoCompare does not crawl social platforms continuously — update frequency depends on coin popularity. Verify the `Points.Twitter.Points_Day` value before using it as a live sentiment signal.
