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 up to $0.018 per request with x402 USDC on Base or choose the fixed-price Solana USDC option when advertised. Exact fixed-price payment and Base upto token-metered payment are both accepted when clients support them; upto settlements use actual response usage, a 0.0001 minimum, and the selected tier price as the cap.
