Tools as reported by the server

• query_channel
  Run a retrieval-augmented query against a channel's indexed knowledge base and return a generated answer with citations. Maps to POST /v1/query. Requires the key's `query` scope and access to the channel. Charged: $0.02 flat per call by default. Prices are the service defaults; `quote` returns the e
• list_channels
  List the channels the calling key is scoped to. Maps to GET /v1/channels. Cursor-paginated. Requires the key's `read` scope.
• list_sources
  List the sources (video/document/website) in a channel, optionally filtered by type or status. Maps to GET /v1/channels/{channelId}/sources. Cursor-paginated. Requires the key's `read` scope.
• get_source
  Fetch a single source and its processing status (type-specific provenance included). Maps to GET /v1/sources/{sourceId}. Requires the key's `read` scope.
• add_source
  Add a source to a channel and begin background ingestion. Maps to POST /v1/channels/{channelId}/sources. Only `type: video` is processed today; `document` and `website` are reserved and return a 501 error until released. Charged from the key owner's prepaid balance at the ingest rate: $0.01/min stan
• get_usage
  Get usage and spend in dollars for the calling key: the account balance (wallet_usd), this period's spend (consumed_usd), query count, and budget remaining. Maps to GET /v1/usage. Requires the key's `read` scope.
• quote
  Free. Expand YouTube URLs exactly as an ingest would and return the price, the per-video lines and the per-source rejections. Maps to POST /v1/quote. $0.01/min standard, $0.03/min whisper by default, 1-minute minimum per video. The `quote_id` is valid for 15 minutes; pass it to `transcribe` or `add_
• transcribe
  Charged. Create a collection and start an ingest job for the given YouTube URLs in one call. Maps to POST /v1/transcribe. $0.01/min standard, $0.03/min whisper by default, 1-minute minimum per video. Pass a `quote_id` from `quote` to be charged exactly that price. Returns `job_id`, `collection_id` a
• create_collection
  Free. Create an empty collection to add sources to later with `add_sources`. Maps to POST /v1/collections. Returns the collection and its `collection_token` (`ct_…`, shown once: store it; absent on an idempotent replay). API key required (the key's `write` scope). Prices are the service defaults; `q
• add_sources
  Charged like `transcribe`. Expand the given YouTube URLs, charge for the new work and start an ingest job in an existing collection. Maps to POST /v1/collections/{collectionId}/sources. $0.01/min standard, $0.03/min whisper by default, 1-minute minimum per video. Videos already in the collection are
• get_status
  Free. Get an ingest job started by `transcribe` or `add_sources`. Maps to GET /v1/jobs/{jobId}. Poll every 10–30 s until `status` is completed, partial or failed (terminal). `completed` means every accepted video is transcribed and indexed, so the collection is queryable; `partial` means some videos
• get_transcript
  Free. Get the transcript of a video that is completed in one of your collections. Maps to GET /v1/videos/{youtubeId}/transcript. `collection_id` is required with an API key; with the collection's `ct_` token as the bearer it defaults to the token's collection. `format` is json (segments with timesta
• query_collection
  Charged: $0.02 flat per call by default, no token multiplier. Ask a question of a collection and get a generated answer with citations. Maps to POST /v1/collections/{collectionId}/query. Query a collection once `get_status` says completed. With an API key it needs the key's `query` scope. Without an

  Ask a question across about 490 curated 2026 conference talks and get a generated answer whose citations give each talk's video URL (with t=) and start_seconds, plus its conference, year and speakers.
