Enumerates the newest videos of a channel, @handle or playlist and returns each video's metadata and transcript in a single call. Pass "search: your query" instead of a channel to go straight from a question to transcripts without knowing which creator to ask - the top results come back with full transcripts. Useful for building a corpus on a topic or from one creator.
