cancel_transcripts_job
Cancel batch job
Cancel a batch job. Credits are refunded ONLY for videos not started yet — anything already fetched stays in the results and stays paid for. Free.

get_credits
Credit balance
Check the remaining credit balance of the API key. Free. Use it when the user asks how many credits are left, or before submit_transcripts_job to confirm a large batch fits the balance (the batch charges 1 credit per video on submit).

get_transcript
Get transcript
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_transcripts_job
Batch job progress
Check the progress of a batch job: status (queued/running/done/cancelled), how many videos are ready, failed and still pending. Free — polling a job you already paid for costs nothing. Read the transcripts themselves with get_transcripts_results.

get_transcripts_result
One batch result
Read ONE video's result out of a batch job by its video id, without paging through get_transcripts_results. 404 means the job does not exist or this video has not finished yet — check get_transcripts_job before concluding anything. Free.

get_transcripts_results
Batch job results
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.

get_video_info
Get video info
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_channel_videos
Search within a channel

search_playlist_videos
Search within a playlist
Find videos inside a playlist by a substring of the title (case-insensitive). YouTube has no native playlist search, so this scans up to 500 playlist items. truncated=true means there may be more matches beyond the scanned window.

submit_transcripts_job
Submit transcripts batch
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_...).
