UA Lookup

Parse, validate and get detailed user-agent information from a user agent string or from client hints.

This API has the following features:

Type Detection

Determine the general user-agent type e.g. check if the user-agent is a phone, tablet or desktop device

Mobile Detection

Determine if the user-agent belongs to a mobile device and get brand and model information

Device Specs

Retrieve device specs such as the release year, price and physical display properties

Browser Detection

Get the name, engine, version and release year of the browser software

Bot Detection

Check if the user-agent is a robot, spider, crawler or other type of automated software

OS Detection

Determine the operating system family, full OS name and version information
For browsers that use client hints you can obtain the complete 'high entropy' user agent data with the following JavaScript code:
The resulting JSON data can then be passed directly to the 'ua' API parameter.

API Request
uayesstringThe user-agent string to lookup. For client hints use the 'UA' header or the JSON data directly from 'navigator.userAgentData.brands' or 'navigator.userAgentData.getHighEntropyValues()'
ua-versionnostringFor client hints this corresponds to the 'UA-Full-Version' header or 'uaFullVersion' from NavigatorUAData
ua-platformnostringFor client hints this corresponds to the 'UA-Platform' header or 'platform' from NavigatorUAData
ua-platform-versionnostringFor client hints this corresponds to the 'UA-Platform-Version' header or 'platformVersion' from NavigatorUAData
ua-mobilenostringFor client hints this corresponds to the 'UA-Mobile' header or 'mobile' from NavigatorUAData
device-modelnostringFor client hints this corresponds to the 'UA-Model' header or 'model' from NavigatorUAData.
You can also use this parameter to lookup a device directly by its model name, model code or hardware code, on android you can get the model name from: https://developer.android.com/reference/android/os/Build.html#MODEL
device-brandnostringThis parameter is only used in combination with 'device-model' when doing direct device lookups without any user-agent data. Set this to the brand or manufacturer name, this is required for accurate device detection with ambiguous model names. On android you can get the device brand from: https://developer.android.com/reference/android/os/Build#MANUFACTURER
