SignCheck by AgentGate

Pre-sign safety check for agent wallets: send a transaction, EIP-712 typed data (Permit, Permit2, EIP-3009, Seaport), an EIP-7702 authorization, or an x402 402 + payment payload. Returns SAFE/CAUTION/DANGER, a plain-English summary and every risk flag (unlimited or EOA approvals, setApprovalForAll, fake USDC domains, x402 overpay, OFAC SDN) plus on-chain facts and eth_call 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://api.youraitools.co/signcheck/v1/check", { method: "GET" });
console.log(await res.json());
