Request an episode's transcription

Queues an episode discovered in its podcast's back catalogue (transcript_status requestable) to be transcribed. Returns 202 with the new request that queues the episode, the only outcome billed as a transcription. Returns 200, billed as a lookup, when there is nothing to transcribe: you have requested the episode before (the existing request), another organization's request already queued it (your own request, tracking it), or we already hold the episode (no request is created, and state says where its transcript stands). There is no limit on how many episodes you request. Requests are transcribed concurrently, usually within a few minutes; a large batch is worked through as earlier requests finish, with organizations served by plan and then evenly. Poll GET /v1/podcasts/transcription/requests/{id} or the episode's transcript_status. The episode keeps its ID once transcribed, and every episode endpoint then serves it. 422 episode_audio_unavailable when its audio cannot be fetched. Send an Idempotency-Key to retry safely: a retry under the same key returns the first response and is not billed.
