APIs/Useragent

User agent parsing API

GET /useragent

Turn a User-Agent into device, OS, browser, and bot answers, down to brand and model (SM-G998B becomes Samsung Galaxy S21 Ultra 5G). Bots come back named and categorized, AI crawlers included.

Bare GET /useragent parses the User-Agent that made the request. No key needed. Prefer the User-Agent request header. Forward Sec-CH-UA-* Client Hints when you have them. Modern Chrome freezes the UA string, and hints are how you get the real model and OS version back. Paid deep adds the full detail.

Parsing User-Agents since 2015. Over 400 million requests and 14 million distinct strings.
