• add_sourceAdd a source to a channel

  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 standard, $0.03/min whisper by default, 1-minute minimum per video. A short balance returns a 402 error. Requires the key's `write` scope.

• add_sourcesAdd YouTube sources to a collection

  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 free. Pass a `quote_id` from `quote` to be charged exactly that price. Poll `get_status` every 10–30 s until `status` is completed, partial or failed; `completed` means every accepted video is transcribed and indexed, so the collection is queryable. API key required (the key's `write` scope). Price…

• create_collectionCreate an empty 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; `quote` returns the exact price.

• get_sourceGet a sourceread-only

  Fetch a single source and its processing status (type-specific provenance included). Maps to GET /v1/sources/{sourceId}. Requires the key's `read` scope.

• get_statusGet an ingest jobread-only

  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 failed and were credited back (`credited_usd`); `videos.completed` / `videos.failed` count progress. Works with an API key or the collection's `ct_` token as the bearer. Prices are the service defaults; `quote` returns the exact price.

• get_transcriptGet a video's transcriptread-only

  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 timestamps, default) or text (one `[H:MM:SS] text` line per segment). 404 when the video is not completed in that collection, or the transcript predates the transcript cache. Prices are the service defaults; `quote` returns the exact price.

• get_usageGet usage and spendread-only

  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.

• list_channelsList channelsread-only

  List the channels the calling key is scoped to. Maps to GET /v1/channels. Cursor-paginated. Requires the key's `read` scope.

• list_sourcesList sources in a channelread-only

  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.

• query_channelQuery a channelread-only

  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 exact price.

• query_collectionQuery a collectionread-only

  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 API key this tool is payable in USDC via x402: the first call returns a payment-required result (`isError` with the payment requirements in `structuredContent`); an x402-aware MCP client signs and retries the same call with `_meta['x402/payment']`, and the receipt returns in the result's `_meta['x4…

• quoteQuote an ingestread-only

  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_sources` to be charged exactly this price. Pass `collection_id` to price against an existing collection (videos already in it are free). At least one of url, urls, channel_url, channel_urls. Requires the key's `read` scope. Prices are the service defaults; `quote` returns the exact price.

• search_talksSearch 2026 conference talksread-only

  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. Optional filters: conference (one of ai-engineer-worlds-fair, ai-engineer-europe, kubecon-eu, google-cloud-next, microsoft-build, pycon-us, google-io, code-with-claude, openai-devday), year, and speaker (part of a name, case-insensitive; speakers are known for about half the talks, so a speaker filter misses the rest). A filter that matches no talk answers `answer: null` and costs nothing. Maps t…

• transcribeTranscribe into a new collection

  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` and `collection_token` (`ct_…`, shown once: store it; it reads this collection without an API key). Poll `get_status` every 10–30 s until `status` is completed, partial or failed; `completed` means every accepted video is transcribed and indexed, so the collection is queryable. With an API key it nee…
