Irreversibly delete a transcript's stored content. AssemblyAI retains a tombstone that later GET and list calls can still return, and those later responses may omit the is_deleted marker.

Export a completed transcript as raw SRT or WebVTT subtitle text.

Get the processing status and short-lived signed download URL for PII-redacted audio. The transcript must have been submitted with text and audio PII redaction enabled and at least one explicit redaction policy. Treat the returned URL as transient and do not log, cache, or persist it.

Retrieve an AssemblyAI transcript's current state and results, optionally waiting until asynchronous processing completes or fails.

Return sentence- or paragraph-level segments, timestamps, confidence, and words for a completed transcript.

List project transcripts from the last 90 days, newest first, with optional filters and a cursor for the next older page.

Find words or phrases in a completed transcript and return occurrence counts and timestamps.

Queue an asynchronous pre-recorded transcription from a reachable media URL. Returns immediately with the transcript ID and processing status; use GET_TRANSCRIPT to wait for results.

Upload an audio or video file to AssemblyAI and return the project-private URL to use when submitting a transcript. AssemblyAI provides no API to delete this uploaded object; it remains subject to provider retention.
