IPstack

API

Geolocation API to locate and identify website visitors via IP address

Overview

IPstack provides RESTful endpoints for real-time IP geolocation and identification. Key endpoints include single IP lookup (supports IPv4/IPv6) and batch queries for multiple IPs. Responses are in JSON, containing data like country, region, city, latitude/longitude, ISP, organization, connection details, and (premium) proxy/vpn detection. Use cases include website personalization, fraud prevention, content localization, and compliance with location-based regulations. It scales from small projects to enterprise needs with tiered plans.
