What Is ip-api?
ip-api.com is an IP geolocation API launched in 2012 that looks up the geographic location and network details of an IP address or domain.
It has become one of the more widely used free geolocation services among developers, reporting more than a billion requests processed per day across its global infrastructure.
Key Features
The API returns location coordinates, timezone, ISP, organization, and AS number data, along with proxy and hosting-provider detection, and supports both IPv4 and IPv6 addresses.
Results can be returned in JSON, XML, CSV, Newline, or PHP-serialized formats, and the service runs on dedicated servers in the US, EU, and APAC using Anycast routing to keep response times typically under 50 milliseconds.
ip-api Pricing
The free tier requires no API key or account signup but is restricted to non-commercial use and limited to 45 requests per minute per IP address, with HTTP 429 responses if the limit is exceeded.
A paid Pro service is available for commercial use, removing the rate limit and adding unlimited queries, SSL/HTTPS access, usage statistics, and dedicated support.
Key Features
Geolocation lookup — Returns city, region, country, and coordinates for an IP address.
ISP and ASN data — Identifies the internet service provider and autonomous system for an IP.
Proxy/hosting detection — Flags IPs associated with proxies or hosting providers.
