Classify or detect text | EmpirioLabs AI Docs

Specialized endpoint for classification-style models that don’t fit chat / search / image. Currently powers GPTZero (AI text detection, bibliography scan, source analysis). Each model’s scan_type enum controls the detection mode. see the per-model docs for the full parameter surface.

Note: GPTZero is also reachable via POST /v1/chat/completions and POST /v1/responses: pass the text on the message body and the gateway adapts the call.
