Overview

Abstract IP Geolocation API converts any IP address into detailed location data including country, city, timezone, and currency information. It is a reliable commercial API with a free tier of 20,000 monthly requests. An API key is required and easy to obtain by signing up on the Abstract website.

💡

Beginner Tip

The free tier gives you 20,000 requests per month — plenty for small projects. You can detect the visitor's own IP automatically by not passing an ip_address parameter, which is handy for personalization features.
