payable
Deterministic pre-sign screening of an x402 recipient: check the raw payTo address against sanctions lists, drainer/phishing/mixer heuristics, and prior on-chain behavior before your agent signs. Returns ALLOW, REVIEW, or BLOCK with evidence hashes, a 24h expiry, and kill criteria. Agents got wallets and nobody watches who they pay; this is the watch.
