Kekkai Currency API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Kekkai Currency API free to use?
Kekkai Currency 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 Kekkai Currency API need an API key?
Kekkai Currency API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call Kekkai Currency API from browser JavaScript?
Not directly. Kekkai Currency API did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is Kekkai Currency API still working?
Not at our last check on 2026-09-18. Kekkai Currency 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 Kekkai Currency API available over HTTPS?
Yes. Kekkai Currency API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
