Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
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.
naun_health reads open 5h ago
WHEN: Liveness / health before paid work or diagnosing connectivity. OUTPUT: Health JSON (environment, commercial_revenue_eligible=false, prices). LIMITATION: Liveness only — not a paid SKU; does not prove a URL is fetchable. PRICE: Free — never charges. Next (suggestion only): naun_capabilities then appropriate paid tool.

WHEN: On-demand check whether a URL fingerprint changed since a prior observation (caller schedules repeats). OUTPUT: changed, material, observation_id, delta, finalUrl, timestamp. LIMITATION: Not a polling SKU; not visual AI; live fetch each observation; format-only may be changed=true material=false. PRICE: $0.005 USDC (Base Sepolia) via x402 per successful check. TESTNET/STAGING. Next (suggestion only, never auto-invoked): store observation_id; if material → web_fetch_clean / web_extract_json.

WHEN: Need cleaned public page (title + Markdown) without a browser. OUTPUT: title, markdown, finalUrl, retrievalTimeMs. LIMITATION: STANDARD HTTP only; no browser/JS render/PREMIUM/RENDERED; JS-heavy = best-effort SSR/HTML. PRICE: $0.003 USDC (Base Sepolia) via x402 per successful call. TESTNET/STAGING. Next (suggestion only, never auto-invoked): web_extract_json → change_detect.

WHEN: Discover tools, prices, networks, limits before paying. OUTPUT: Catalog object (tools + limitations + prices). LIMITATION: Read-only staging catalog; never invents mainnet/commercial. PRICE: Free — never charges. Next (suggestion only): pick paid tool matching job; confirm Base Sepolia USDC.

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 id23c7065113b217ec.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/23c7065113b217ec/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.
