Is the x402 service you want actually tested?

Your agent’s first x402 call

The fastest way to use this: have your agent buy the full tested-services dataset over x402. One call, \$0.10 on Base, no API key, no signup. It returns one JSON: every service + verdict + evidence_grade + the exact request + the real response + the on-chain tx.

// needs: a key funded with a little Base USDC + `npm i x402-fetch viem`
import { wrapFetchWithPayment } from "x402-fetch";
import { createWalletClient, http, publicActions } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";

const account = privateKeyToAccount(process.env.PRIVATE_KEY);
const wallet  = createWalletClient({ account, chain: base, transport: http() }).extend(publicActions);
const pay     = wrapFetchWithPayment(fetch, wallet); // auto-pays on HTTP 402

const res  = await pay("https://402atlas.com/api/verified");
const data = await res.json();
console.log(data.total, "services", "— read data.reading_guide first");
