AssemblyAI provides speech-to-text transcription and audio intelligence APIs for uploaded and remotely hosted media.

## Tools

- **Delete Transcript Content** — 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 Subtitles** — Export a completed transcript as raw SRT or WebVTT subtitle text.
- **Get Redacted Audio** — 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 tr
- **Get Transcript** — Retrieve an AssemblyAI transcript's current state and results, optionally waiting until asynchronous processing completes or fails.
- **Get Transcript Segments** — Return sentence- or paragraph-level segments, timestamps, confidence, and words for a completed transcript.
- **List Transcripts** — List project transcripts from the last 90 days, newest first, with optional filters and a cursor for the next older page.
- **Search Transcript** — Find words or phrases in a completed transcript and return occurrence counts and timestamps.
- **Submit Transcript** — 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 Media** — 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.
