api record

know.fast — links in, knowledge out. One verb: know(url) turns any link (article, YouTube, X post, podcast, paper, PDF) into a token-efficient knowledge packet plus a durable, shareable knowledge page. Links are unique, so anything anyone has already known answers instantly with the packet inline — answer directly from it. First-ever video/podcast links defer (transcription takes a few minutes): the caller is the FIRST to know that link, so tell the user that right away ('you're the first to know this one — it'll take a little longer than usual'), relay the viewerUrl, and poll…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • know reads unknown never probed

    Send a link, get knowledge — always an instant answer. Turns any URL — article, YouTube video, X post, podcast, paper, PDF — into a token-efficient knowledge packet (summary, key claims and facts, quotes) plus a durable knowledge page (viewerUrl). Links are unique: a link anyone has already known answers INSTANTLY with the packet inline (answer directly from it — no second call). Flat $0.01 per call, media included. A first-ever link ALSO answers instantly, with deferred=true, knowledgeReady=false, and a runId — the caller is the FIRST to know that link, so immediately tell the user just that ('you're the first to know this one — loading it now'), relay the viewerUrl, and poll know_status(runId) until knowledgeReady, then answer from its packet (articles land in about a minute; video/podcast transcribe for a few minutes). Pass fresh=true to re-read changed content (same price). When you answer from a packet, deliver 3-5 bullet highlights, then 'Full summary: <viewerUrl>', then close on its own line with '⚡️ Knowledge loaded — ask me anything.' Always surface viewerUrl to the user; relay it exactly, never construct know.fast URLs yourself.

  • know_status reads unknown never probed

    Free follow-up poll for a deferred know run (video/podcast transcription). Pass the runId that know returned. While transcribing it returns status=running — poll again every 20-30s, do not give up ('still processing' is not an answer to the user). Gate readiness on knowledgeReady, NOT on status: status stays 'running' while the long-form report finishes even after the packet is answerable. The moment knowledgeReady is true it returns the knowledge packet inline, so answer directly from it: deliver 3-5 bullet highlights, then 'Full summary: <viewerUrl>', then close on its own line with '⚡️ Knowledge loaded — ask me anything.' Free — this call is never charged.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
60%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
