ISO 3166-2 API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is ISO 3166-2 API free to use?
ISO 3166-2 API is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up. Free tiers can still carry rate limits or non-commercial terms, so check the provider's own terms before shipping.
Does ISO 3166-2 API need an API key?
No. We called ISO 3166-2 API on 2026-09-18 with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.
Can I call ISO 3166-2 API from browser JavaScript?
Yes. ISO 3166-2 API 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.

Yes, as of 2026-09-18. Our automated check reached ISO 3166-2 API and recorded a 100% reliability score with a median response time of 502 ms. We re-check on a schedule, and this page updates with the result.
