Pre-transaction counterparty risk screening for autonomous agents. Screens wallet addresses or agent IDs with dated OFAC and high-risk-contract snapshots, six-chain nonce/balance/code reads, and bounded one-hop funding data. Returns an ed25519-signed PASS / FLAG / BLOCK signal verifiable against a pinned key. Holds no caller wallet key or downstream transaction/escrow authority; Vouchgate separately settles only its caller-authorized x402 fee. Roadmap checks are labelled in each result.
