Mode API Quickstart

To use the Mode API you’ll need to create a free Alchemy account first!

Introduction

Mode is an OP Stack–based, EVM-equivalent Ethereum Layer-2 that’s growth-focused—sharing sequencer fees with developers (SFS) and rewarding users to power DeFi/AiFi apps.

What is the Mode API?

The Mode API allows interaction with the Mode network through a set of JSON-RPC methods. Its design is familiar to developers who have worked with Ethereum’s JSON-RPC APIs, making it intuitive and straightforward to use.

Getting Started Instructions

1. Choose a Package Manager (npm or yarn)

Select a package manager to manage your project’s dependencies. Choose between npm and yarn based on your preference or project requirements.

$
# Begin with npm by following the npm documentation
>
# https://docs.npmjs.com/downloading-and-installing-node-js-and-npm

2. Set Up Your Project

Open your terminal and execute the following commands to create and initialize your project:

$
mkdir mode-api-quickstart
>
cd mode-api-quickstart
>
npm init --yes

This creates a new directory named mode-api-quickstart and initializes a Node.js project within it.

3. Make Your First Request

Install Axios, a popular HTTP client, to make API requests:

$
npm install axios

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

1
const axios = require('axios');
2
3
const url = 'https://mode-mainnet.g.alchemy.com/v2/${your-api-key}';
4
5
const payload = {
6
  jsonrpc: '2.0',
7
  id: 1,
8
  method: 'eth_blockNumber',
9
  params: []
10
};
11
12
axios.post(url, payload)
13
  .then(response => {
14
    console.log('Latest Block:', response.data.result);
15
  })
16
  .catch(error => {
17
    console.error(error);
18
  });

Remember to replace your-api-key with your actual Alchemy API key that you can get from your Alchemy dashboard.

4. Run Your Script

Execute your script to make a request to the Mode network:

$
node index.js

You should see the latest block information from Mode’s network outputted to your console:

$
Latest Block: 0x...

Next Steps

Congratulations! You’ve made your first request to the Mode network. You can now explore the various JSON-RPC methods available on Mode and start building your dApps on this innovative platform.
