AgentPay x402 Facilitator missed 3 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

x402

x402_facilitator_settle

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.

x402_facilitator_verify

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.

How do I connect AgentPay x402 Facilitator?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does AgentPay x402 Facilitator need an API key?

No. AgentPay x402 Facilitator completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is AgentPay x402 Facilitator?

It answers our handshake in 541 ms on average, which is faster than 21% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
