Detect whether a contract is an upgradeable proxy and resolve its implementation: reads the standard EIP-1967 implementation/admin/beacon slots, EIP-1822 (UUPS), the OpenZeppelin legacy slot, and EIP-1167 minimal-proxy bytecode. Returns the proxy type, implementation, admin and beacon addresses when present. Reads live on-chain data with automatic endpoint fallback.

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://chain.openverbs.com/v1/proxy", { method: "POST" });
console.log(await res.json());
