GeoJS

Overview

GeoJS is a free IP geolocation API — IP → city, country, coordinates, timezone, and ASN data, with CORS support for browser use (verified live). Keyless with generous limits, it’s a great zero-config IP lookup.

Quick Start

Lookup your own IP (verified live):

curl "https://get.geojs.io/v1/ip/geo.json"
