Legacy minimal alias of /screen. Returns result 'caution' (with reportCount, crimeTypes and any OFAC SDN sanctions entries) when reports, an OFAC SDN match or a current Tether/Circle freeze are found, otherwise 'no_c3_reports', plus action, actionReason, sanctioned, frozen and freezes. 'no_c3_reports' is not a guarantee that the address is safe.

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

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

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://blockint.ai/api/v1/c3-reports/check/:address", { method: "GET" });
console.log(await res.json());
