About ipapi.co

ipapi.co provides a REST API for retrieving the geographic location of an IP address. For a given IPv4 or IPv6 address, it returns data including city, region, country, continent, postal code, latitude and longitude, timezone, UTC offset, EU membership status, country calling code, capital, top-level domain, currency, country area and population, languages spoken, ASN, and organization. Hostname lookup is available as an optional beta add-on upon request.

Requests are made via HTTP GET to an endpoint of the form https://ipapi.co/{ip}/{format}/, with responses available in JSON, XML, CSV, YAML, or JSONP. Individual fields can also be requested directly (e.g., country only) rather than the full response. The API can be called from either server-side or client-side code, and can also be used to determine the public IP address of the requesting device.

Code examples are provided for Ruby, Python, PHP, JavaScript, Node.js, jQuery, Java, C#, and Go, making the service usable across a range of programming environments without requiring a specific client library.
