• accountPlan and usage balancesread-only

  The plan, Cloud Request balance and AI Processing 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. Includes the monthly reset date and browser links to top-ups and plans; supporting clients show an interactive card.

• analyze_videoAnalyze a video’s frames and speech

  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. A fresh analysis spends 1 Cloud Request plus AI Units per minute of video — Quick 2.8, Standard 4, Deep 30 — and a captionless video is analyzed from its picture and soundtrack at no extra charge (transcribeAudio adds a word-for-word transcript for 3 more per minute). Before a long video or a Deep run, call it with estimateOnly: true — free — …

• ask_videoAsk a question about an analyzed video

  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. Each citation carries `at`, a `youtubeUrl` that opens the video at that second and, when available, a `frameUrl` still; the cited frames are attached as images. Cite them to the user as [12:34](youtubeUrl) links. Costs 6 AI Units per question.

• get_analysisRead a finished video analysisread-only

  Display a saved AI Watch analysis and its interactive chat UI. Free. Omit analysisId to open this account’s latest finished analysis, including results created on the website or through another client. Use list_analyses to find older results. If the client cannot render the UI, show the analysis in the chat with its timestamp links. Pass waitSeconds (up to 25) to have the server hold the call until the analysis finishes or the wait runs out, instead of polling repeatedly. While status is "queued" or "processing" the analysis field is absent — call again. When "ready" it contains the summary, c…

• get_transcriptGet full video transcripts

  Fetch the complete transcript text for one or more YouTube videos, or just the part between two timecodes. Costs 1 Cloud Request per video the account does not already have; re-reading a video already in its library (another time range, another page) is free, and each result reports what it `charged`. 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. When the user names a time span ("what was said between 10:20 and 11:00"), pass from/to rather than fetching the whole thing.

• list_analysesList my AI Watch analysesread-only

  Saved AI Watch analysis history, newest first, with analysisId, video, mode and status. Free. Use this for previous analyses; list_library lists transcripts instead. Call get_analysis with a returned analysisId to display the full result and its chat UI. For the latest finished analysis, call get_analysis with no arguments.

• list_channel_videosList a channel’s recent videosread-only

  Resolve a YouTube channel handle, URL or id to its recent uploads. Costs 1 Cloud Request. Requires the Starter plan or higher.

• list_languagesList a video’s caption languagesread-only

  The caption tracks a video has — language code, name, and whether it is auto-generated — so you can pass the right `lang` to get_transcript instead of guessing. An auto-generated track transcribes the speech; an uploaded one may be a translation. Free, and answers only from a stored tracklist; a video without one reports known:false rather than costing a Cloud Request.

• list_libraryList my saved videosread-only

  The videos this account has saved, newest first, with title, channel, language and whether the transcript is searchable with search_library. Free. Use it to see what the user already has before fetching anything; page with `before` set to the last item’s `savedAtMs`. Also returns latestAnalysis with the latest finished AI Watch analysisId: call get_analysis with that ID to display the full analysis.

• list_watchlistsList Radar watchlistsread-only

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

• search_librarySearch my saved transcriptsread-only

  Full-text search across every transcript this account has already saved, returning the matching moments with timestamps and deep links. Free — no Cloud Request, no AI Units. Try this FIRST when the user asks about something they have watched or researched before, and before fetching a video again with get_transcript or search_transcript.

• search_transcriptSearch video transcripts

  Search one or many YouTube videos for a phrase or topic and return the matching moments with timestamps and deep links you can cite. Costs 1 Cloud Request per video the account does not already have (the transcript is fetched to search it); searching a video already in its library is free. Use this instead of get_transcript when the user asks what a video says about something — pass a list to answer "what does this channel say about X" in a single call (get the ids from list_channel_videos first).

• translate_transcriptTranslate a transcript with AI

  Translate one video’s transcript into ANY language with AI, line for line: every caption line keeps its timestamp, so the translation reads, cites and downloads like the original. Use it when the user wants the transcript in a language the video has no captions in (get_transcript then answers `language_unavailable` with `aiTranslation`), or wants an audio transcription translated. YouTube’s own caption translations stay on get_transcript’s `lang`. Price: 2 AI Units per started minute of video (a 10-minute video costs 20), plus 1 Cloud Request if the video is not in the library yet. The whole t…

• watchlist_activityRecent uploads on a watchlistread-only

  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.
