GeoJS — Free IP Geolocation API (No Key)

TL;DR

GeoJS is a lightweight, free IP geolocation API that detects the visitor's location from their IP address. It returns country, region, city, latitude/longitude, timezone, currency, and ASN information. The API is blazingly fast with no authentication and no rate limits documented. Just call the endpoint and get back structured JSON. Perfect for client-side geolocation needs where you don't want to ask for browser permission.

Frequently Asked Questions

What data does GeoJS return?: The geo endpoint returns: ip, country, region, city, latitude, longitude, timezone, currency_code, currency_symbol, asn, organization, country_code, and continent_code.
Is there a rate limit?: GeoJS does not document any strict rate limits. It's designed for high availability and can handle frequent requests from client-side applications.
Does it work with IPv6?: Yes, GeoJS supports both IPv4 and IPv6 addresses. Pass any valid IP in the URL path.
How accurate is the location data?: Accuracy is at the city level for most IPs. The exact coordinates come from a geolocation database and may represent the approximate center of the city or ISP service area.
Can I use GeoJS on the client side?: Absolutely. Since it requires no API key and supports CORS, you can call it directly from JavaScript in the browser without any server-side proxy.
What other endpoints are available?: Besides /v1/ip/geo.json, there's /v1/ip.json (just your public IP), /v1/country.json (just country), /v1/ip/country/{ip}.json, and /v1/dns.json (DNS lookup).
