FREE Client Info API

Introduction

The Free Client Info API provides a quick and simple way to identify the public IPv4 address and browser details of your users. It also includes proxy detection by analysing the X-Forwarded-For (XFF) HTTP header field, along with detailed User-Agent (UA) information. This gives you a clear overview of your visitor’s identity and the device they are using to access your services.

Important Notice: While the API is free to use with no throttling limits, we expect responsible usage. Excessive or unreasonable requests, such as repeatedly querying the same IP address at high volumes, are prohibited and may result in restricted access. If you encounter errors or connection blocks despite adhering to reasonable usage practices, please contact our support team for assistance.
