json-repair-api-9ybv.onrender.com

Automatic before-payment firewall for x402 clients. Runs after the merchant returns PAYMENT-REQUIRED but before the wallet creates/signs the merchant payment. Returns ALLOW, REVIEW or BLOCK based on exact request/challenge integrity and public merchant/payTo risk evidence. Spending authority remains with the caller's wallet/client policy unless full transaction clearance is used.

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://json-repair-api-9ybv.onrender.com/trust/x402/firewall", { method: "POST" });
console.log(await res.json());
