Build a single wallet/agent pre-signing decision pack from optional EIP-712 typed data, EVM calldata, expected chain, known addresses, and x402 spend policy. Returns risk levels, risk flags, buyer decision, copy-paste checklist, and first-payment routing hints without using a private key, producing a signature, sending a transaction, broadcasting, or calling external RPC. Pay $0.018 per request with x402 exact USDC on Base or Solana when advertised. Canonical live prices: https://gpt55.558686.xyz/x402/live-prices.json.
