Sanctions Screening (OFAC, EU, UN)

Screen a person or company name against the official OFAC SDN list (with aliases), the EU consolidated financial sanctions list and the UN Security Council consolidated list. Fuzzy, word-order independent matching with scores, list, program and aliases. Lists refresh every 12 hours. A screening aid, not a legal determination. Params: name (required), type ('individual' or 'entity', optional), threshold (0.5 to 1, default 0.85), limit (default 10).

Call it

import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agentsvc.io/api/v1/proxy/sanctions-screen", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({"name":"Banco Nacional de Cuba"}),
});
const { data, payment } = await res.json();  // payment.transaction = on-chain receipt
