Kraken — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Kraken free to use?
Kraken 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 Kraken need an API key?
Yes. Kraken 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 Kraken from browser JavaScript?
We could not confirm CORS support for Kraken. 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 Kraken still working?
Not at our last check on 2026-09-18. Kraken 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 Kraken available over HTTPS?
Yes. Kraken serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
