AI agents can call video.transcript to get transcript text, timestamped segments, detected language, source, and media duration for supported public YouTube and Vimeo media.

Call with a public URL

For URL input, the CLI lazily downloads and verifies yt-dlp, fetches audio locally, resolves duration, checks the price, and sends the extracted audio for transcription.

Prefer official captions

This YouTube-only path does not fall back to ASR when captions are unavailable.

Pricing and limits

  • ASR is billed per minute, with a one-minute minimum.
  • Maximum duration is 120 minutes.
  • Supported URL hosts are YouTube and Vimeo.
  • Use --async for long media and query the invocation later.
Agents must not use OpenTooler to bypass private, DRM-protected, or members-only media restrictions. Respect source-platform terms.
