Know the limits

Not every video has retrievable captions. Private, restricted or unavailable content may fail. This endpoint retrieves available transcripts; it does not promise transcription of every video.

Bulk requests accept up to five explicit video URLs per API call, with a separate result and charge outcome for each video.
