Seller due-diligence for one x402 endpoint. We make a real capped test payment, check the paid response against the listed schema, compare payTo with the CDP listing, read a recent window of on-chain USDC payments to the payTo and screen for lookalike addresses. Returns a signed JSON verdict of evidenced facts. No charge unless the test payment and all 4 other checks complete. Facts, not endorseme

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://horizonpulse.dev/api/seller-dd/single", { method: "POST" });
console.log(await res.json());
