VerifyLite

Approval check for one wallet and one ERC-20 token on Base: how much each spender (up to 10 app or router addresses) is allowed to move, flagging unlimited approvals and approvals covering the full balance, plus approvals made through Uniswap Permit2 with their expiry. Defaults to checking Permit2 itself. Useful before signing, for wallet hygiene, and for spotting approvals to revoke. Read-only. N

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://verifylite.hydratinghealingtouch.workers.dev/chain/allowance", { method: "POST" });
console.log(await res.json());
