Built from a daily index of the CDP Bazaar catalog, unpaid 402-quote checks and Lumi Trades' own on-chain test purchases on Base, the XRP Ledger and Stellar. Optional payTo and amount inputs catch address or price mismatches. A free signed version is at

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://api.lumitrades.io/v1/trust/check", { method: "GET" });
console.log(await res.json());
