Pre-trade safety verdict for AI agents. One signed call returns SAFE / CAUTION / BLOCK before your agent executes a transaction: OFAC SDN sanctions screening (address + counterparty), stablecoin peg deviation (bps), and counterparty on-chain signal. Scoring only — never executes trades.
Price: 0.02 USDC per call, x402 on Base (eip155:8453). No account, no API key — the payment is the auth.
