Capabilities

Tools 14

cancel_transcripts_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.

Discovered
get_credits

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).

Discovered
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.

Discovered
get_transcripts_job

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.

Discovered
get_transcripts_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.

Discovered
get_transcripts_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.

Discovered
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.

Discovered
latest_channel_videos

Get the ~15 most recent videos of a channel from its RSS feed. Fastest and cheapest way to check what a channel published recently.

Discovered
list_channel_videos

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.

Discovered
list_playlist_videos

List videos of a playlist in playlist order. Accepts a PL... playlist id or a URL with list=. ids_only=true returns just video ids (up to 500 per page).

Discovered
search_channel_videos

Search videos inside one channel using YouTube's native relevance search. Results are ranked by relevance, so a video whose title lacks the query word is normal.

Discovered
search_playlist_videos

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.

Discovered
search_youtube

Search YouTube for videos or channels. Paginate by passing next_page_token from the previous result. has_more tells you whether another page exists.

Discovered
submit_transcripts_job

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_...).
