v3 is deprecated - support ends in 2018. v4 is newest version - Upgrade now.
The Detector v3 API provides tools for identification, submission, building and debugging.
The recommended identification request method is made using a server-side request and storing the segment in the users session, as this provides the best user experience and fewest possible requests to the Detector server. See our implementation guide for simplified examples.
Be aware of our terms.
The API is available at http://detector-v3.dearapi.com.
