# IP Info by Shifter

> Free public IP geolocation and ASN API. No signup. No API key. Maintained and supported by Shifter.

Use GET https://ip-info.com/myip for only the caller's IP as plain text (address plus newline). Use GET https://ip-info.com/json for the caller's network exit or GET https://ip-info.com/json?ip=ADDRESS for a public IPv4/IPv6 literal. For compact JSON with only country_code, region, city and timezone, use GET https://ip-info.com/json_lite or GET https://ip-info.com/json_lite?ip=ADDRESS. country_code maps to country in the full response. All four lite keys are always present. HTTP is also supported. The caller may be an agent's server or proxy, not its human user. Missing fields are null; locations are approximate. No application quota; acceptable-use terms and finite capacity apply.
