CoinGecko
Crypto prices and market data with a real free demo tier.
CoinGecko exposes coin prices, market charts and exchange data. The free demo tier works without a card but enforces strict per-minute limits that tighten during market volatility — our checks catch the throttling windows other directories miss. Response shapes have shifted twice this year; see the change log below.

CoinGecko: common questions
Is CoinGecko free to use?
Yes — CoinGecko is a free finance API. Free tier: 10k calls/mo demo key, no card. Whether the free tier allows commercial use is unclear — check the provider docs.
Does CoinGecko need an API key?
Yes — CoinGecko needs a free API key, which you pass on each request. Rate limits: ~30/min, tightens under load.
Can I call CoinGecko from the browser?
Not directly — CoinGecko doesn't send browser-friendly CORS headers, so call it from a server or proxy instead. Copy the curl or Python snippet on this page to get started.
Is CoinGecko up right now?
As of our last scheduled check, CoinGecko is degraded. We re-probe it every sweep — the status badge and uptime chart above always show the latest.
