GET
/v1/youtube/video/transcript

Returns the spoken transcript of a video as timestamped segments, each with text, start time and duration, plus language, word count, and speech rate.

Use it for a single video URL; when the video has no captions the reply is a 404 naming the reason, which is expected rather than a failure.

30 credits per call.
