How do I get my IP address with this API?

Send a GET request to https://ipchu.com/api/ip. The response is JSON containing the caller's IP address, geolocation, timezone, ASN, and ISP — no API key or signup required.

Do I need an API key?

No. The endpoint is free and open, with no authentication, API key, or signup. CORS is enabled so it can be called directly from browser JavaScript.

Is there a rate limit?

There is no hard rate limit, but the endpoint is offered on a best-effort basis with no uptime SLA. Avoid hammering it in tight loops — cache the result if you need the same data repeatedly.

Not cached (Cache-Control: no-store) — every request reflects the current caller.

Free and best-effort. This API has no uptime SLA and no rate-limit guarantees. It's provided as a convenience — please don't build production infrastructure that depends on it without your own fallback.
