Inspects any EVM contract: detects EIP-1967 and EIP-1167 proxies and their implementation, reads the owner, checks Sourcify verification, and lists capabilities (mint, pause, blacklist, burn, upgrade) from the logic contract's bytecode.

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://sift.srv1996466.hstgr.cloud/v1/crypto/contract", { method: "GET" });
console.log(await res.json());
