YouTube Transcript API

The captions of one YouTube video in the language you ask for, as timed segments (start, duration, text) plus the full text. Human-made captions are preferred and YouTube's auto-generated ones are the fallback; the response says which you got and lists every caption language on offer. Uses only the caption tracks the public watch page links to. Videos without captions in that language, verification pages, blocks and failures are free.

This engine is built but paused: YouTube now requires a browser attestation token for captions, which we will not fake. Join early access through the contact form and we'll email you on launch day.
