Pre-sign safety verdict: one call decodes a pending transaction and checks sanctioned counterparties, unlimited-approval/drainer patterns, contract-vs-EOA, and whether it would revert — returning SAFE / CAUTION / DANGER with reasons. Send { chain, to, data, from?, value? }. The must-have guard every signing agent needs. [x402 paid tool — price $0.05; POST /api/safety/guardrail]
