what callers paid
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.
create-pay-link unknown never probed
For an agent that holds no wallet, or when the principal should approve the spend themselves: POST https://iomarkets.app/v1/links returns a URL the human opens, where they see the exact price and sign it in their own Pera wallet. The key never leaves their wallet and the agent never holds one. The deliverable (an eSIM's activation QR, a top-up confirmation) appears on the same page.
buy-airtime unknown never probed
Send mobile airtime or data to a phone number. GET /v1/lookup?phone=+919876543210 detects the country and operator and lists offers; the detected operator is a guess for MVNOs and must be confirmed with the human before buying. Paid per order in USDC on Algorand over x402.
buy-esim unknown never probed
Buy a travel data eSIM and receive the activation QR / LPA string. Paid per order in USDC on Algorand over x402 — no account, no API key, no card. Browse with GET /v1/catalog?type=esim&country=JP, lock a price with POST /v1/quote, pay POST /v1/orders.
verify-receipt unknown never probed
Verify an ed25519-signed proof-of-delivery receipt: the signature, which server signed it, and both the settlement and refund transactions against an Algorand indexer. Free, unauthenticated, and it verifies receipts from ANY server that adopts the format — not only this one. POST https://iomarkets.app/v1/verify with the receipt as the body (add ?online=0 to skip the chain lookup). Format: https://iomarkets.app/receipts.md
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 id13caa806030c608d.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/13caa806030c608d/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.
