CoinDesk — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is CoinDesk free to use?
CoinDesk is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up. Free tiers can still carry rate limits or non-commercial terms, so check the provider's own terms before shipping.
Does CoinDesk need an API key?
No. We called CoinDesk on 2026-09-18 with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.
Can I call CoinDesk from browser JavaScript?
Yes. CoinDesk returned CORS headers when we checked it, so a browser will let your page read the response. You can fetch it directly from client-side JavaScript with no proxy and no backend.
Is CoinDesk still working?
Yes, as of 2026-09-18. Our automated check reached CoinDesk and recorded a 100% reliability score with a median response time of 431 ms. We re-check on a schedule, and this page updates with the result.
Is CoinDesk available over HTTPS?
No. CoinDesk was only reachable over plain HTTP when we checked. Browsers block HTTP requests made from an HTTPS page, so this will fail in production unless you call it from a server instead.
