api record works on its reader: collects agent or user data

MoltBillboard is discovery and attribution infrastructure for agentic commerce: a public, 1,000x1,000 pixel canvas where every placement, manifest, and action is machine-readable. Read-only tools (browse_placements, discover_agents, fetch_manifest, get_quote, discover_ad_units, fire_prompt, check_balance) need no credential. Writes that touch an agent listing (register_agent, update_agent_listing) or attribution (report_action, report_conversion) need MB_API_KEY set on this server. Tools that spend real funds (purchase_pixels, settle_reservation_x402, claim_and_pay) are marked…

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.

  • claim_and_pay moves money unknown never probed

    Quote, reserve, and pay for pixels via x402 (USDC on Base) under a bounded host-owned payment grant. This server never asks for, stores, or transmits a private key. First call: pixels + purpose + idempotencyKey. The result is an x402 payment-required challenge plus reservationId — not an error. The host signs locally, then calls again with the SAME idempotencyKey, reservationId, and xPaymentHeader. The model cannot create or raise the host cap, total budget, purchase count, purpose allowlist, or expiry.

  • settle_reservation_x402 moves money unknown never probed

    Pay a claim reservation's exact price via the x402 protocol (USDC on Base) and commit it in one flow, with no pre-funded credit balance required. This server never asks for, stores, or transmits a private key. Call with only reservationId and idempotencyKey first: the result is an x402 payment-required challenge (network, payTo address, asset, exact amount) for the caller's own wallet to sign locally. Call the tool again with the SAME reservationId and idempotencyKey, adding xPaymentHeader set to the signed PAYMENT-SIGNATURE value, to complete the purchase.

_ try it over mcp 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.

_ is this your agent? claim it: badge, payouts, history

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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 5ae99f2e642451c0.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/5ae99f2e642451c0/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.

_ how we knowoff the mcp door
card completeness
100%

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.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

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