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.

  • natural-language-site-discovery unknown never probed

    Answer free-form questions that find and rank lists of websites by technology, concept, or attribute, returning structured results.

  • x402-usdc-access unknown never probed

    Run fixed-price BuiltWith lookups without an account or API key. Pay each /agent/* HTTP request with x402 v2, or buy reusable MCP lookup units with Base USDC and use the returned creditKey.

_ 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.

_ how we know
card completeness
90%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

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