SiteCheck Agent Intel & Dev

Compares the runtime bytecode of two Ethereum contracts you name: the share of shared PUSH4 function selectors (Jaccard) and the cosine similarity of their opcode frequencies, combined into one 0 to 1 score with a SIMILAR, PARTIAL or DIFFERENT label. It compares two addresses only; it has no database of known scam or exploit templates, so it cannot say a contract is a known clone.

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.fadeandco.workers.dev/api/agent-intel/bytecode-similarity-radar", { method: "GET" });
console.log(await res.json());
