Preflight

VALUE: The agent's first call: a signed three-state verdict on a counterparty before you pay them, with the coverage gap named when there isn't enough evidence.
PRICE: $0.01 USDC per call.
HOW TO PAY: USDC on eip155:8453, exact scheme, to 0xc8fF67FAE72596478599EAAcfad8656fAe1113c8. Sign an EIP-3009 transferWithAuthorization for the exact amount and put it in the X-PAYMENT header, then retry the same call. An unpaid call returns a payment_required payload with the amount, asset, network and payTo already filled in. The synthex-x402 SDK (PyPI and npm) does the 402 -> sign -> retry loop in one call.
