x402-seller — rug protection for autonomous trading agents

Live: https://x402-seller-m8nx.onrender.com · Base mainnet · no signup, no API key — pay per call in USDC via x402

Your agent is about to ape into a token. One bad ape costs its whole position. This API answers "is this a rug?" in one call, with evidence:

Composite rug score — GoPlus static analysis fused with a live Honeypot.is buy/sell simulation (it actually executes a simulated trade), a serial-rugger check, hard honeypot gates, and a needs_review flag when the two engines disagree.
Solana too — dual-engine (GoPlus-Solana + RugCheck): mint/freeze authorities, holder concentration, LP burn. Different chain, different rug physics, same design.
Liquidity-drain detector — we poll pool reserves over time and answer "is liquidity leaving right now?" — the earliest sign of a rug in progress. This time-series exists nowhere for free; you can't backfill history you didn't collect.
Public self-graded track record — every 30 minutes we score fresh Base launches with the exact paid scorer, then grade ourselves against what actually happened. Hits and misses published. Evidence, not claims.

Try it free, right now

Buy with three lines (any x402 client)

import { wrapFetchWithPayment } from "@x402/fetch";
import { privateKeyToAccount } from "viem/accounts";

const payFetch = wrapFetchWithPayment(fetch, privateKeyToAccount(process.env.PK));
const r = await payFetch("https://x402-seller-m8nx.onrender.com/vet?chain=base&address=0x…");
// 402 → auto-pay USDC on Base → data. That's the whole integration.
