ipapi.com API
Overview
ipapi.com provides a fast REST API to geolocate any IP address and retrieve location data like country, city, timezone, and ISP in JSON format. It offers a free plan with 1,000 requests per month so you can prototype without a billing setup. It is a good fit for apps that need to detect a user's location automatically from their IP.
Beginner Tip
You can test the API without a key by hitting the /json endpoint — it will geolocate your own request IP. Add your API key as ?access_key=YOUR_KEY for higher limits and full field access.
