Sanctions-screen an EVM wallet address against the Chainalysis on-chain oracle (OFAC, EU, UN designated addresses). Returns a clear sanctioned / not-sanctioned result. For AML compliance, counterparty due diligence, and payment screening before sending funds.
Evaluate a proposed payment against a structured, caller-supplied policy and optional recipient sanctions screening, before execution. Returns ALLOW, REQUIRE_APPROVAL, or BLOCK with reasons, plus a signed OCD PREFLIGHT receipt anyone can independently verify. Policy evaluation only: OCD never holds, moves, or authorizes funds. The wallet, PayBox, or x402 client independently authorizes execution afterward; an ALLOW here does not guarantee it will proceed.
