IPGuardian — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is IPGuardian free to use?
IPGuardian 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 IPGuardian need an API key?
No. We called IPGuardian on 2026-09-27 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 IPGuardian from browser JavaScript?
Yes. IPGuardian 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 IPGuardian still working?
Yes, as of 2026-09-27. Our automated check reached IPGuardian and recorded a 100% reliability score with a median response time of 896 ms. We re-check on a schedule, and this page updates with the result.
Is IPGuardian available over HTTPS?
Yes. IPGuardian serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
