}Poll job status, progress, and (once completed) the transcript
Polls a job. Unlike the synchronous create and episode-read operations, format has no default here — omitting it and passing ?format=json are different requests. Without ?format= the response is application/json status only: the job status object, and artifact is never present, regardless of status. ?format=json must be given explicitly to also receive the transcript: the same status object, now carrying artifact once status is completed — artifact is never implied by completed alone, so a caller polling for state does not repeatedly ship a whole transcript (see JobStatus).
Delivery format. format: text|srt|vtt|md on a completed job returns the raw artifact under its own media type (text/plain, application/x-subrip, text/vtt, text/markdown) rather than a JSON envelope, with provenance carried in headers — X-Transcript-Episode-Id, X-Transcript-Source, and X-Transcript-Timing-Precision — so every delivery format carries the same provenance. The single content-type switch: a payload over the ~5 MB inline limit returns 200 application/json with { transcript_url, expires_at } in every format, including the raw ones.
A non-json format against a job that is not completed is 409 job_not_completed — there is no artifact to render yet, and the answer is to keep polling with no format (or with format=json) until the job is terminal. It is not a reason to wrap the status object in a different media type.

}Authorizations
Authorization: Bearer hk_live_... for live keys or Authorization: Bearer hk_test_... for test-mode keys. hk_test_ keys resolve real public catalog metadata but return deterministic committed fixtures, never call inference, and never mutate live credits. This is the only transport for the credential: the x-api-key alias once documented was removed in 0.2.0, because the edge authorizer reads Authorization as its single identity source and a request on any other header is refused before it is authenticated.
Never accepted on a dashboardJwt operation, and there are no exceptions. GET /v1/usage and GET /v1/limits briefly declared both schemes (0.8.0); that was withdrawn in 0.8.1 because no deployed route could honor it — both operations are served by the control-plane API, whose authorizer verifies a Cognito token and refuses an hk_live_ credential on shape, and the customer API does not route either path. An API-key holder reads its balance and reservation from QuoteResponse, which carries balance_credits and reserved_credits on every quote. Every operation in this document takes one scheme or the other and refuses the wrong one as unauthenticated.
Path Parameters
Opaque, server-generated job identifier.
40^job_[A-Za-z0-9]{16,32}$Query Parameters
The derived output to return from GET /v1/transcripts/{job_id}. No default — deliberately not FormatQueryParam, which defaults to json on the operations where delivering content is the whole point of the call. Polling is different: the status-only option exists precisely so a caller can ask for state without shipping the transcript, and a default would make omitting format and passing format=json the same request, erasing that option. So: omit format entirely for status only — application/json, the job status object, artifact never present, whatever status is. Pass format=json explicitly to also receive the transcript once status is completed — the same status object, now with artifact. Pass format=text|srt|vtt|md to receive the raw artifact under its own media type (text/plain, application/x-subrip, text/vtt, text/markdown) once completed; against a job that has not reached completed, any non-status format is 409 job_not_completed.
Delivery-only: never affects the cache key or the produced transcript content.
Delivery-only: never affects the cache key or the produced transcript content. Every format is derived at read time from the one canonical transcript. Response media type per format: json → application/json, text → text/plain, srt → application/x-subrip, vtt → text/vtt, md → text/markdown. The one exception is an oversized payload, which is application/json in every format (see TranscriptUrlRef).
json, text, srt, vtt, md Response
Job status — status only when format is omitted, artifact included when status is completed and format=json was explicitly requested — or the completed raw artifact (format=text|srt|vtt|md), or, for an oversized payload in any format, the transcript_url reference.
- Option 1
- Option 2
Failure/cancellation objects report reservation_released: true and never imply a cash refund occurred — a cash refund is a separate, explicit Stripe refund via POST /v1/billing/refund.
Opaque, server-generated job identifier.
40^job_[A-Za-z0-9]{16,32}$Legal transitions: validating → queued|failed|cancelled; queued → downloading|failed|cancelled; downloading → transcribing|failed; transcribing → merging|failed; merging → completed|failed. Terminal states (completed, failed, cancelled) have no further transitions. Cancellation is legal only from validating/queued; every non-terminal state may fail.

^ep_[a-z2-7]{16}$A non-negative JavaScript-safe integer credit amount. The upper bound matches Number.MAX_SAFE_INTEGER, which is enforced by the domain ledger so arithmetic and JSON round-trips cannot silently lose cents worth of credit precision.

The completed transcript, in JSON delivery. Present only when status is completed and the caller explicitly asked for it with ?format=json on GET /v1/transcripts/{job_id} — PollFormatQueryParam has no default, so omitting format there is a real, distinct request that never carries artifact, whatever status is. It is deliberately not required by completed: a client polling a finished job would otherwise be forced to re-download the whole transcript on every call, with no status-only option.
