Base Launch Guard

Exit liquidity check for an open Base token position: simulates selling your position (USD size or raw token amount) on the deepest pool and returns net received, price impact / slippage, the largest position that exits under 3% impact, the measured sell tax and an EXIT_TRAP flag (> 15% impact). For trading agents monitoring memecoin positions; cheap enough to poll.

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://guard.facts402.com/v1/guard/exit", { method: "POST" });
console.log(await res.json());
