Agent Verifier — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Agent Verifier free to use?
Agent Verifier 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 Agent Verifier need an API key?
No. We called Agent Verifier on our last run 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 Agent Verifier from browser JavaScript?
Not directly. Agent Verifier 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 Agent Verifier available over HTTPS?
Yes. Agent Verifier serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
