ICD-10 Codes — common questions

Answered from what our own scheduled checks found, not from the provider's marketing.

Is ICD-10 Codes free to use?

ICD-10 Codes 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 ICD-10 Codes need an API key?

No. We called ICD-10 Codes 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 ICD-10 Codes from browser JavaScript?

Yes. ICD-10 Codes 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 ICD-10 Codes still working?

Yes, as of 2026-09-18. Our automated check reached ICD-10 Codes and recorded a 100% reliability score with a median response time of 2284 ms. We re-check on a schedule, and this page updates with the result.

Is ICD-10 Codes available over HTTPS?

Yes. ICD-10 Codes serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
