Search one YouTube video for a phrase or topic and return the matching moments with timestamps and deep links you can cite. Costs 1 credit per video (the transcript is fetched to search it). Use this instead of get_transcript when the user asks what a video says about something.

Fetch the complete transcript text for one or more YouTube videos. Costs 1 credit per video. Prefer search_transcript when you only need the parts about a specific topic — full transcripts of long videos are large and mostly irrelevant to the question.

Resolve a YouTube channel handle, URL or id to its recent uploads. Free — no credits are spent. Requires the Starter plan or higher.

The account’s Radar watchlists — the YouTube channels it monitors for new uploads — with how many new videos each has recorded. Free.

The most recent videos Radar has recorded for one watchlist, newest first. Free. Pair with search_transcript to answer questions about what those videos said.

The plan and credit balance for the calling token. Free. Check this before a large batch so you can tell the user what a job will cost instead of failing partway through it.

Start a deep visual analysis of a YouTube video: chapters, key moments, on-screen text and evidence tied to exact timestamps. Reads the picture, not just the captions, so it can answer questions about a slide, chart or demo the transcript never mentions. Spends Watch minutes from the plan. Returns immediately with an analysisId — analysis takes minutes, so poll get_analysis rather than waiting. If the video was analyzed before, it comes back ready at once.

Fetch the analysis started by analyze_video. Free. While status is "queued" or "processing" the analysis field is absent — poll again. When "ready" it contains the summary, chapters, key points and timestamped evidence.

Ask a question against a finished analysis and get an answer whose citations are verified against the stored evidence: a visual claim must match a real recorded frame and a spoken one a real transcript segment, or it is dropped. When nothing survives, the answer says the evidence is insufficient rather than guessing. Spends one Watch question from the plan.
