🟢coldread_check(url, method, pay_to, agent)
Before paying an x402 seller: one signed, independent report combining a 402-challenge lint, signed-offer and signer-authorization checks, an ERC-8004 identity lookup and a labelled Base USDC payer summary over the last ~28 h. Read-only; never pays. Free.
