Request · Response · Guide: Split & classify

More details

One endpoint covers both modes; the mode is selected by the payload (not a separate endpoint):

no options -> normal (open) classification: the engine proposes document types
schemas -> custom (closed-set) classification against the supplied candidate document types Classification supports no free-text prompt or instruction.

Always returns 202 Accepted with a job_id; results are retrieved via GET /v1/jobs/ (result.document_class carries the primary classification) or delivered to callback_url when the job settles.Supported input types: application/pdf, image/png, image/jpeg, image/tiff. Any other content type is rejected with 415.
