Decide whether an autonomous agent both can and should execute an exact x402 payment. Verifies predelegated spending authority, challenge/request integrity, and public merchant transaction-risk signals, then returns an evidence-based APPROVED, REVIEW or DENIED clearance plus a signed clearance token. APPROVED means the agent may proceed autonomously; REVIEW means do not auto-pay until higher-level review; DENIED means do not pay.

Settlement assurance for a completed x402 payment on Base or Solana: confirm the transaction succeeded (0x hash or base58 signature), match the USDC transfer to an expected wallet and amount, format a receipt, and optionally audit the issuing endpoint - as one 0-100 scored report with a verdict.

Explain what an EVM transaction would actually do: decodes the calldata (ERC-20 transfers/approvals via known ABIs, unknown selectors via the 4byte directory) and simulates the call against live chain state to report the outcome — including unlimited-approval warnings — without sending anything. Use this when an agent needs to decode and simulate a transaction — before signing it.
