Heartbeat

Best free crypto price APIs

Public spot-price endpoints that work without a key. Ranked by measured 7-day uptime, then speed. Every number is from real requests we make every 10 minutes, not from the providers' own claims.

On the last 26 checks, CoinGecko leads on both reliability (100.00% uptime) and speed (80 ms median from Sweden).

Latency is measured from a single server in Sweden including DNS and TLS. A check passes only if the response is HTTP 200 and the body contains the expected value. Live page, updated every 10 minutes.
