What is the GeoJS API?

GeoJS is a free IP geolocation API with no API key and no published rate limit, returning country, region, city, coordinates, timezone, ASN and organisation over HTTPS with full CORS and JSONP support.

GeoJS stands out among free IP geolocation services for having no rate limit at all and full HTTPS with CORS — the combination that ip-api's free tier lacks and ipapi.co restricts.

It also supports JSONP, which is unusual now but genuinely useful for static sites that need geolocation without any backend at all. The ASN and organisation fields make it useful for detecting hosting providers and VPN ranges.

How to use the GeoJS API

Every request below was executed against the live API on 2026-08-19, and the response shown is the real body it returned — not an illustration.

1. Geolocate the calling IP address

GET https://get.geojs.io/v1/ip/geo.json

curl
curl 'https://get.geojs.io/v1/ip/geo.json'
JavaScript (fetch)
const res = await fetch("https://get.geojs.io/v1/ip/geo.json");
if (!res.ok) throw new Error(`Request failed: ${res.status}`);
const data = await res.json();
console.log(data);
Python (requests)
import requests

res = requests.get("https://get.geojs.io/v1/ip/geo.json", timeout=20)
res.raise_for_status()
print(res.json())

What you can build with the GeoJS API

  • Geolocate visitors from a static site with no backend, via CORS or JSONP
  • Detect hosting providers and VPNs using ASN and organisation
  • Set default currency or language by country
  • Add geographic context to logs and analytics

Common errors and how to fix them

Coordinates as strings

Latitude and longitude are JSON strings.

Fix: Parse to numbers before using with a mapping library.

Inaccurate city

IP geolocation is approximate.

Fix: Check the `accuracy` field — a large radius means the city is a rough guess.

VPN gives wrong location

Expected behaviour for any IP geolocation.

Fix: Use the organisation field to spot hosting and VPN providers.

GeoJS API — frequently asked questions

Is GeoJS free and rate limited?

It is free with no API key and no published rate limit, which is unusual among IP geolocation services.

Can I call it from a static website?

Yes. It supports both CORS over HTTPS and JSONP, so it works from a purely client-side site with no backend at all.

How accurate is it?

Country level is reliable; city level is approximate. The `accuracy` field gives a radius in kilometres, which you should respect rather than treating the city as exact.

Can it detect VPNs?

Not directly, but the ASN and organization_name fields identify the network operator, which usually reveals hosting providers and commercial VPN ranges.
