Finnhub — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Finnhub free to use?
Finnhub is listed in our free catalogue, but it requires an API key, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does Finnhub need an API key?
Yes. Finnhub authenticates with an API key. Keep it server-side rather than in browser code, because anything in your frontend bundle is readable by anyone who opens developer tools.
Can I call Finnhub from browser JavaScript?
Yes. Finnhub 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 Finnhub still working?
Yes, as of 2026-09-18. Our automated check reached Finnhub and recorded a 100% reliability score with a median response time of 7437 ms. We re-check on a schedule, and this page updates with the result.
Is Finnhub available over HTTPS?
Yes. Finnhub serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
