Token Security Check

Risk check for an ERC20 token on Base, Ethereum, BNB Chain, Arbitrum or Polygon before buying or accepting it: honeypot simulation, buy/sell tax, mintable, owner can change balances, hidden owner, blacklist, pausable transfers, proxy, unverified source, holder concentration, LP lock, DEX liquidity, pair age and volume. Returns a verdict (low, medium, high, critical, or incomplete if the security feed is down) with concrete flags. Sources: GoPlus Security, DexScreener, on-chain RPC. Params: token (contract address, required), chain (base default, ethereum, bsc, arbitrum, polygon).

Call it

import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agentsvc.io/api/v1/proxy/token-security", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({"token":"0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed","chain":"base"}),
});
const { data, payment } = await res.json();  // payment.transaction = on-chain receipt
