CurrencyFreaks — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is CurrencyFreaks free to use?
CurrencyFreaks 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 CurrencyFreaks need an API key?
Yes. CurrencyFreaks 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 CurrencyFreaks from browser JavaScript?
Yes. CurrencyFreaks 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 CurrencyFreaks still working?
Yes, as of 2026-09-18. Our automated check reached CurrencyFreaks and recorded a 100% reliability score with a median response time of 322 ms. We re-check on a schedule, and this page updates with the result.
Is CurrencyFreaks available over HTTPS?
Yes. CurrencyFreaks serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
