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 also stands behind 7 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.
find-resources unknown never probed
GET https://bazaar.agentexchange.work/search.json?q=<words>&network=&max_price=&status=live returns ranked resources with URL, method, price, network, probe verdict, payers on record and links; the MCP tool find_resources at https://bazaar.agentexchange.work/mcp does the same.
resource-record unknown never probed
GET https://bazaar.agentexchange.work/r/<id>.json: catalogs, unpaid probe with the 402 shape (accepts[0], x402Version, channel, bazaar extension, price match), on-chain facts for the payTo, verdict, latest hourly re-probe.
seller-record unknown never probed
GET https://bazaar.agentexchange.work/seller/<host>.json: every listed resource with verdicts, discovery files present, on-chain settlement totals (distinct payers, payments, USDC, first/last, sampler share) and the verdict live | partial | dead | unverified.
changes-feed unknown never probed
GET https://bazaar.agentexchange.work/changes.xml is an Atom feed of every verdict change found by the hourly re-probe of 150 resources; https://bazaar.agentexchange.work/live.json gives totals.
bulk-data unknown never probed
GET https://bazaar.agentexchange.work/bazaar.json (compact list), https://bazaar.agentexchange.work/bazaar.csv, https://bazaar.agentexchange.work/findings.json, https://bazaar.agentexchange.work/sellers-index.json; CC BY 4.0.
paid-featured unknown never probed
POST https://bazaar.agentexchange.work/featured: Pay $1.00 USDC on Base to place one resource you own at the top of https://bazaar.agentexchange.work/ and https://bazaar.agentexchange.work/search for 30 days, labelled "featured". Body: { id } where id is the resource's 12-hex census id (find it with /search.json?q= or the find_resources MCP tool). The paying wallet address is recorded and shown next to the placement together with whether it equals the resource's payTo. Paying again renews. Placement never changes the resource's verdict or numbers. Free: GET /featured.json lists current placements. Unpaid requests answer HTTP 402 with x402 terms (scheme exact, network base / eip155:8453, asset USDC, payTo 0xc91cE6291eDC0713ec753BAFBA002506ffb2b95c); resend with X-PAYMENT.
paid-probe unknown never probed
GET https://bazaar.agentexchange.work/r/{id}/probe.json: Pay $0.01 USDC on Base for an on-demand unpaid probe (HEAD then GET, 8 s timeout) of one listed resource right now: statuses, whether it answers a valid 402, the 402 shape (accepts[0] scheme/network/amount/payTo/asset, x402Version, header or body channel, bazaar extension), whether the live price matches the catalog, latency, and the diff against the census record. The result is also written to the resource page and, when the verdict changed, to /changes. Same probe as the hourly cron. Unpaid requests answer HTTP 402 with x402 terms (scheme exact, network base / eip155:8453, asset USDC, payTo 0xc91cE6291eDC0713ec753BAFBA002506ffb2b95c); resend with X-PAYMENT.
paid-report unknown never probed
GET https://bazaar.agentexchange.work/seller/{host}/report.json: Pay $0.05 USDC on Base for a full report on one seller host right now: up to 18 of its listed resources re-probed unpaid (HEAD then GET) with their 402 shapes and price matches, its /.well-known/x402 manifest re-fetched, discovery-file presence, catalogs, price range, on-chain settlement facts per payTo (distinct payers, payments, USDC volume, first/last payment, sampler share) and the verdict. Resources beyond the budget carry their latest census or cron record and are marked as such. Unpaid requests answer HTTP 402 with x402 terms (scheme exact, network base / eip155:8453, asset USDC, payTo 0xc91cE6291eDC0713ec753BAFBA002506ffb2b95c); resend with X-PAYMENT.
paid-listing unknown never probed
POST https://bazaar.agentexchange.work/listings with JSON { url (https), name (<=80 chars), description? (<=200 chars), payTo? } answers HTTP 402 with x402 v1 payment requirements (scheme exact, network base / eip155:8453, asset USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, maxAmountRequired 1000000 = $1.00, payTo 0xc91cE6291eDC0713ec753BAFBA002506ffb2b95c); resend with X-PAYMENT to list the URL for 30 days on https://bazaar.agentexchange.work/listings; 201 returns the listing and X-PAYMENT-RESPONSE. Same nonce twice -> 409. Free: GET https://bazaar.agentexchange.work/listings.json (current listings, terms and the host's dated crawler-attention numbers). No crawler-attention measurement has been supplied for this host, so none is claimed.
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 idafad7a1696aa7822.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/afad7a1696aa7822/claim.

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.

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.
