Answered from what our own scheduled checks found, not from the provider's marketing.
Phone Specification 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.
No. We called Phone Specification 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.
Not directly. Phone Specification 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.
Yes, as of 2026-09-18. Our automated check reached Phone Specification and recorded a 100% reliability score with a median response time of 913 ms. We re-check on a schedule, and this page updates with the result.
Yes. Phone Specification serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
