Create Classifier

POSThttps://api.confident-ai.com/v1/classifiers

Creates a classifier that tags incoming traces or threads with labels. Classifiers run on TRACE and THREAD items only, and a name is unique per data model within the project.

Passing a preset seeds the classifier with a description, a generation config, and a starting set of labels; any field you send explicitly overrides what the preset would have set. SENTIMENT arrives with its labels ready, while USE_CASES and ISSUES ship with none and expect you to call the generate endpoint next. Retrieve the classifier by id to read back what the preset seeded. Requires the Starter plan or above.
