Verified by x402station

A $1 USDC audit badge for x402 service operators. Embed it in your docs / landing page to prove uptime, latency, and clean signal-set to agents that visit. Pure machine-to-machine — your CI bot pays our signal endpoint, no human signup involved.

What you get for $1 USDC

Audit criteria

The same predicates fire on issuance AND on every public-page re-render. If your endpoint passes here, your CI bot can mint a cert today.

Eligible right now (60 endpoints, 60 verified+)

Live snapshot of the catalog, refreshed every 5 min. If you recognise your endpoint below, you can mint a cert with the curl command on its row.

How to mint

One command from your CI bot (or any wallet-bound x402 client). Replace $URL with the endpoint URL you saw in the eligibility list.

# Using @x402/fetch — auto-signs PAYMENT-SIGNATURE with your wallet
import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";

const fetch2 = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{
    network: "eip155:8453",
    client: new ExactEvmScheme(privateKeyToAccount(process.env.PK)),
  }],
});

const r = await fetch2("https://x402station.io/api/v1/verified", {
  method: "POST",
  headers: { "content-type": "application/json" },
  body: JSON.stringify({
    url: "https://your-endpoint.example.com/route",
    name: "Your Service",
  }),
});

const cert = await r.json();
console.log("Badge URL:", cert.badgeUrl);
console.log("Public page:", cert.pageUrl);
console.log("HTML snippet:", cert.htmlSnippet);
// Cert valid for 30 days. Re-call to renew.

Why this exists

x402station.io independently probes every endpoint on the public catalog ( see the heatmap). Roughly 17% of the catalog is landmines (decoy / zombie / dead). Agents visiting your service have no easy way to tell yours apart from those — the badge gives them a verifiable trust signal, backed by 7-day probe history they can re-check at any time. Cheap enough that a single weekly re-cert at $1 is rounding error in your infra spend.
