Api Key Development Tutorials, Guides & Insights

• $response->status(): Returns the HTTP status code.
• $response->header('header-name'): Retrieves a specific response header.

In this tutorial, we covered how to handle various HTTP requests in Laravel using the Http facade, including:

const axios = require('axios');

// Replace this with your actual Etherscan API key
const apiKey = 'YOUR_ETHERSCAN_API_KEY';

// Replace this with the Ethereum address you want to query
const address = '0xYourEthereumAddress';

// Etherscan API URL to fetch wallet balance
const url = `https://api.etherscan.io/api?module=account&action=balance&address=${address}&tag=latest&apikey=${apiKey}`;

async function getWalletBalance() {
  try {
    // Make the API request to Etherscan
    const response = await axios.get(url);
    const balanceInWei = response.data.result;

    // Convert balance from Wei to Ether
    const balanceInEther = balanceInWei / 1e18;
    console.log(`Wallet Address: ${address}`);
    console.log(`Wallet Balance: ${balanceInEther} ETH`);
  } catch (error) {
    console.error('Error fetching balance:', error);
  }
}

// Call the function to get the balance
getWalletBalance();

• Axios is used to make the HTTP request to the Etherscan API.
• Replace 'YOUR_ETHERSCAN_API_KEY' with the actual API key you obtained from Etherscan.
• Replace '0xYourEthereumAddress' with the Ethereum address you want to query.
• The balance is returned in Wei (the smallest unit of Ether). We convert this to Ether for readability by dividing by 1e18.
