Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 16 doors on this origin, so the chain figures are the operator's.

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.
list_apis open 17h ago
Page through seller-authored, publicly listed x402 offers without paying. Prices are previews; the current 402 challenge is authoritative.

Inspect one admitted catalog operation, including its documented input, output, provenance and preview price. Does not settle payment or verify delivery.

Search public offers by literal terms, service section, category, seller and producer. maxFixedPriceAtomic selects fixed-priced offers within this seller's declared network and asset. Inspect the current 402 challenge to purchase.

Inspect two to eight exact public seller SKUs together, with buyer-bounded source-output-example to target-POST-body-schema readings from the original Networking selector. One admitted example is not universal compatibility, workflow authorization, checkout, or delivery.

Wallet-free exact atomic-unit preview of selected seller SKUs and call counts against a total EVM budget. Uses original listed fixed-price source offers only; actual live 402 terms, authorization, payment, and delivery are separate.

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.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idf18b2456c7d99237.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/f18b2456c7d99237/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
