Agent Extraction API

Deterministic ERC-20 risk check on Base or Ethereum from public on-chain data only: privileged functions in bytecode (mint, blacklist, pause, fees, limits, trading switch), upgradeable proxy + implementation, owner and renounce status, Uniswap v2/v3 + Aerodrome liquidity in USD (Chainlink), owner/pool/burned supply share. Every flag has evidence; lists what was NOT checked (no honeypot simulation)

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://freetier-agent-api.pages.dev/api/token-risk", { method: "GET" });
console.log(await res.json());
