ip-api

API

Free IP geocoding API for location and ISP data

Overview

ip-api is a RESTful geocoding API that retrieves location data via IP address or domain. Key endpoints include single lookup (country, region, city, coordinates, ISP, ASN) and batch lookup for multiple IPs. Responses are in JSON (default), XML, CSV, or newline formats. Use cases: geotargeting content, fraud prevention, ad optimization, and personalized user experiences. It supports IPv4/IPv6, with a free tier for non-commercial use (rate-limited) and pro tiers for HTTPS, higher limits, and priority support.

Example Integration (JavaScript)

script.js JS


fetch('https://ip-api.com/docs')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
