openapi: 3.0.0 servers: - url: https://scribe.kensho.com info: version: 1.1.0 title: Scribe Batch API description: 'Scribe''s Batch API allows users to upload audio files for asynchronous processing. Once a file has been uploaded, and unique, randomly generated ID is returned to the user. Users can then use that ID to poll the Scribe Batch API to get results. Accessing these APIs requires passing an authentication header in the standard format of "Authorization: Bearer ". For individual users accessing the API, see the [authentication guide](../../authentication).

This method takes in the unique ID returned from starting a transcription, and returns either a JSON (default) or WebVTT response. If the `Accept` header is missing or of type `application/json` then this call will return a tuple of status, error, and transcript. The status will be one of "success", "error", or "pending". The transcript field will be present if and only if the status is "success". The error field will be present if and only if the status is "error". A status of "pending" indicates that the transcription job is still in progress, in which case neither the transcript nor error will be present. If the `Accept` header is of type `text/vtt` then this call will return the transcription as VTT text tracks.
