Free Real-time Geolocation & Reverse IP Lookup REST API

Overview

ipapi.com is a RESTful API for real-time geolocation and reverse IP lookup. Key endpoints include /ip (requester’s IP geolocation) and /{ip_address} (reverse lookup for IPv4/IPv6). Responses are JSON-formatted, with data like country, region, city, coordinates, ISP, ASN, timezone, currency, and organization. Use cases: fraud detection (verify user location), content localization (region-specific content), targeted ads, compliance with regional rules, and enhancing UX (e.g., local time display). It supports simple HTTP requests for easy integration.

Example Integration (JavaScript)

script.js JS


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