get_transcript

Fetch timestamped captions for a YouTube, TikTok, or Instagram URL when the platform provides them. Use segment start_sec/end_sec (or the flat text) to choose a cut range, then call cut_audio with the same URL and those times. When available is false there are no captions — do not invent lyrics or timestamps; tell the user to pick times another way. Optional lang is a BCP-47 code (default en). No job_id is returned.

Parameters2

url	string	required	YouTube, TikTok, or Instagram URL to fetch captions for
lang	string	optional	Optional BCP-47 caption language (default en)
