Rates Limits API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Rates Limits API free to use?
Rates Limits 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 Rates Limits API need an API key?
Rates Limits API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call Rates Limits API from browser JavaScript?
Not directly. Rates Limits 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 Rates Limits API still working?
Yes, as of 2026-09-18. Our automated check reached Rates Limits API and recorded a 100% reliability score with a median response time of 438 ms. We re-check on a schedule, and this page updates with the result.
Is Rates Limits API available over HTTPS?
Yes. Rates Limits API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
