🟢get_transcript(video, lang, format, kind, segment, ...)
Get the transcript (subtitles) of a YouTube video. Accepts a video id or any YouTube URL. Set video_metadata=true to get the title, channel and duration in the SAME call — do not call get_video_info first, that is a second billed call for data this one already returns. format=text returns plain readable text (default, cheapest to read); format=json returns timed segments with start/duration in seconds; srt/vtt return ready subtitle file bodies and srv3 the raw YouTube XML. Prefer text unless you need timestamps or a file. Costs 1 credit.

}🟢get_video_info(id)
Get metadata for one YouTube video (title, channel, duration, views, thumbnails) plus the list of available transcript languages, WITHOUT downloading the subtitles. Use it only when the transcript itself is not wanted. If you are going to fetch the transcript anyway, call get_transcript with video_metadata=true instead — it returns both for one credit, where these are two separate calls and two credits.

List videos from a channel's Videos tab, newest first. Accepts an @handle, a UC... channel id or a channel URL. ids_only=true returns just video ids (up to 500 per page) — use it when you only need ids to fetch transcripts.

}🟢search_playlist_videos(id, q, limit)

}🟡submit_transcripts_job(videos, lang, format, kind, segment, ...)
Queue transcripts for MANY videos at once (up to 4000) and get a job_id back immediately — the work continues in the background. Use this instead of calling get_transcript in a loop for more than a handful of videos. Feed it video ids from list_channel_videos or list_playlist_videos (ids_only=true). Next: poll get_transcripts_job until status is 'done', reading finished transcripts from get_transcripts_results as they land. Costs 1 credit per video, charged on submit; duplicates are removed first. Requires a user key (sk_...).

}🟢get_transcripts_job(job_id)

Read finished transcripts from a batch job, in the order submitted. Results appear as they are fetched, so this can be called before the job is done. Each entry is exactly what get_transcript returns for that video, plus its status. Page with next_page_token. Free.
