agentpay-x402-facilitator
Registry code: aeb43ce6919da8d9
Goal: safely verify or settle a caller-provided signed x402 payment. Success means: return the existing facilitator result with its authorization checks retained. Stop when: return verification, confirmed settlement, refusal, or an explicitly unknown outcome. Keep private keys with the payer. Check authorization nonce and receipt before retrying an unknown settlement. AgentPay x402 facilitator MCP adapter. Two tools wrap the live localhost facilitator: x402_facilitator_verify (read-only, free) and x402_facilitator_settle (irreversible on-chain settlement through Coinbase CDP). Settlement…

- Is agentpay-x402-facilitator live?
- Yes — it answered the hub's last check (checked 5h ago). It answered 99% of checks over the last 30 days.
- Is agentpay-x402-facilitator free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does agentpay-x402-facilitator have?
- 2 tools: x402_facilitator_verify, x402_facilitator_settle.
- Is agentpay-x402-facilitator safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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

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.
x402_facilitator_verify reads unknown 22h ago
Forward an x402 payment envelope to POST https://x402-agent-pay.com/facilitator/verify. Recovers the EIP-712 signer, checks payee/amount/expiry/nonce/USDC balance and spend authority. Free. No gas. No broadcast. Returns isValid plus invalidReason when the payload cannot clear. Authorization still lives in the existing facilitator implementation; this tool only forwards the JSON body.

IRREVERSIBLE SIDE EFFECT: forwards the envelope to POST https://x402-agent-pay.com/facilitator/settle. The existing facilitator first re-runs verify(), then refuses PAYEE_NOT_SERVED_HERE unless payTo is the AgentPay treasury (0x367F1b3D8Ca90D1e087481a9A40d585Bf3451a03 on Base / 6aCEuwH3PYx99cEmRz45otfxk39uF7ewGhqmvxfXisSG on Solana), then broadcasts via Coinbase CDP and returns a transaction hash. Malformed, unsigned, out-of-scope, or unverified payloads are rejected before any external transfer. This adapter never signs, never holds keys, and never bypasses those gates. Do not call this as a dry run.

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 idaeb43ce6919da8d9.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/aeb43ce6919da8d9/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.
card completeness
60%
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.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
