Ethereum API Overview

Welcome to the Ethereum API Quickstart and Reference Guide. This guide provides everything you need to start building on Ethereum using dRPC’s JSON-RPC API. Whether you're retrieving account balances, fetching block details, executing transactions, or estimating gas fees, this comprehensive guide will help you integrate Ethereum seamlessly into your applications.

This page includes:

A Quickstart Guide to help you set up and make your first Ethereum API request.
A detailed list of all Ethereum API methods, categorized for easy reference.

Ethereum API Quickstart#

To get started with building on Ethereum using dRPC's Ethereum RPC API, follow these steps:

1. Create a dRPC Account or Use Public Ethereum RPC endpoints

By signing up for a free dRPC account, you can access their Premium Ethereum RPC endpoints.

Public endpoints:

HTTPS

https://eth.drpc.org/

WSS:

wss://eth.drpc.org

2. Set Up Your Development Environment

RPC can be requested in various ways (opens in a new tab). In this example, we are going to use Node.js. Ensure you have Node.js (opens in a new tab) and npm installed on your system. You can verify their installation by running:

node -v
npm -v

If not installed, download and install them from the official Node.js website (opens in a new tab).

3. Initialize Your Project

Create a new directory for your project and initialize it:

mkdir ethereum-drpc-quickstart
cd ethereum-drpc-quickstart
npm init --yes

4. Install Axios

Axios is a popular HTTP client for making API requests. Install it using npm:

npm install axios

5. Obtain dRPC Endpoint

Log in to your dRPC account and navigate to the Ethereum RPC endpoints section. Copy the HTTPS endpoint URL for the Ethereum Mainnet.

6. Write Your First Script

Create an index.js file in your project directory and add the following code:

const axios = require('axios');
 
const url = 'https://lb.drpc.org/ogrpc?network=ethereum&dkey=YOUR_DRPC_API_KEY';
 
const payload = {
  jsonrpc: '2.0',
  id: 1,
  method: 'eth_blockNumber',
  params: []
};
 
axios.post(url, payload)
  .then(response => {
    console.log('The latest block number is', parseInt(response.data.result, 16));
  })
  .catch(error => {
    console.error('Error fetching block number:', error);
  });

Replace ‘https://lb.drpc.org/ogrpc?network=ethereum&dkey=YOUR_DRPC_API_KEY' with the actual endpoint URL you obtained from dRPC.

7. Run Your Script

Execute your script using Node.js:

node index.js

You should see the latest Ethereum block number printed in your console.

Additional Information

dRPC offers various features such as high performance nodes, access to multiple chains, and MEV protection. For more details, visit their Ethereum API documentation (opens in a new tab).

By following these steps, you can start building on Ethereum using dRPC's reliable and efficient RPC endpoints.
