Resolve a channel handle, URL, id or name to a channel with its stats.

Useful on its own to confirm which channel a name refers to before searching.

Search one channel's videos by keyword, e.g. the latest iPhone review on MKBHD.

Costs 100 YouTube quota units per 50 results. When you want recent uploads and have no keyword, use list_channel_videos instead — it is 100x cheaper.

List a channel's uploads newest first, optionally within a date range.

Example: everything MKBHD posted in the last year, via published_after='1y'.

Get a video's transcript as timestamped lines you can quote and cite.

Every line starts with a Markdown link that seeks to that moment, so quoting a timestamp back keeps claims traceable and clickable — e.g. "at [03:15] he says the battery is 17% larger than last year". Reproduce those links verbatim rather than rewriting them as plain text. Narrow long videos with start_seconds and end_seconds. Reads public caption tracks, so it costs no API quota.

Get a video's full description, extracted links, tags and engagement counts.

The links list is what the creator cited in the description — sources, products, sponsors and their own other videos.
