Get YouTube video transcript

Automatically get YouTube video transcript on youtube.com. Fetch a YouTube video's caption transcript (auto-generated or uploaded) with per-segment timestamps. Returns available:false when the video has no captions in any language. Some runs fail when YouTube plays an ad before the video, roughly 1 in 3; the script already retries, so if it still fails, call it again later. The paired-extension browser is more reliable than the managed browser, where YouTube often shows a sign-in check and no transcript is returned.

Input

video_id required

YouTube video id, e.g. "jNQXAC9IVRw" (the v= parameter, or the last path segment of a youtu.be link)

Output

segments required
video_id required
available required

false only when the video is playable but has no captions in any language. A video that does not exist, or is private / region-blocked / sign-in-gated, throws instead of reporting false.

language optional

Language code of the track actually returned. Deterministic: the video's default caption track.
