MEV / Sandwich Guard

Agents are the easiest MEV prey: predictable, public-mempool, a measured ~$50M/quarter tax. A sandwich only pays when a trade moves the pool enough to front-run (size vs pool depth). This returns an exposure read (low/elevated/high) and a protected-execution plan: a tight min-out, private/off-mempool inclusion (a Cobalt validity tx via validity-build), and splitting a large order into unattackable

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://402.com.tr/api/x402/mev-guard", { method: "GET" });
console.log(await res.json());
