get_channel_transcripts
Get Channel Transcripts
Get transcripts for a YouTube channel's most recent videos (newest first) as timestamped markdown, one section per video. Use for research across a creator's recent output; for one known video use get_transcript. Read-only; requires an API key. Charges 1 credit per video that returns a transcript, including repeat calls; videos without captions are skipped free. A 10-video call typically costs up to 10 credits, so start with a small limit. Rate limit: 5 requests per 10 seconds.

get_transcript
Get YouTube Transcript
Get the full transcript of a single YouTube video as timestamped markdown. Read-only: fetches existing captions, modifies nothing. Requires an API key; each successful call charges 1 credit, including repeat calls for the same video, so reuse a transcript already in context instead of re-fetching. Videos without captions return an error and cost nothing. Rate limit: 5 requests per 10 seconds.

polish_transcript
Polish YouTube Transcript
Get a cleaned-up transcript of a YouTube video's auto-generated captions: punctuation and capitalisation restored, filler and false starts removed, paragraphs added, misheard names fixed, faithful to what was said. Use when raw captions are too messy to read or quote; for a plain transcript use get_transcript. Read-only; requires an API key. Each call charges credits by transcript length (about 3 per 1,000 words, minimum 5), including repeat calls, so keep the result in context. Human-uploaded captions (already clean) and transcripts over ~7,000 words return an error without charging. Rate limit: 5 requests per 10 seconds.
