工具清单
工具（5）
🟢get_youtube_transcript(video, language, translate_to, format)
Fetch the transcript (captions/subtitles) of a YouTube video as text. Accepts a watch URL, youtu.be link, Shorts link or bare 11-character video id. Returns the spoken text with timestamps grouped in ~30 s blocks by default; format 'text' is prose without timestamps, 'srt'/'vtt' are subtitle files, 'json' is raw segments with start/duration. Works with creator-uploaded and auto-generated captions. translate_to translates the transcript with AI (extra credits, scales with length) — omit unless asked.
