x402_facilitator_verifyread-onlyForward 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.
