import Blocklens from "blocklens-sdk";

const blocklens = new Blocklens();
blocklens.init({ apiKey: "YOUR_API_KEY" });

const runApis = async () => {
  const response = await blocklens.ETH_MAINNET.getErc20MintsByBlockOrHash("0x0517e1369f5159852973c47dc335d28b67ccffb238333542f880abc3fe3ab505");
  console.log(response);
