CoinGecko API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is CoinGecko API free to use?
CoinGecko API is listed in our free catalogue, but it requires some form of authentication, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does CoinGecko API need an API key?
CoinGecko API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call CoinGecko API from browser JavaScript?
We could not confirm CORS support for CoinGecko API. Test it from a browser before relying on it client-side; if the request succeeds in curl but fails in the console, CORS is the reason.
Is CoinGecko API still working?
Not at our last check on 2026-09-18. CoinGecko API did not respond successfully, which is why it is marked as down here. This may be temporary; we re-check on a schedule and the badge above reflects the most recent run.
Is CoinGecko API available over HTTPS?
Yes. CoinGecko API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
