The quickest way to start building on Hyperliquid with Quicknode is by sending a JSON-RPC request to your endpoint. In this quickstart, you’ll create an endpoint, copy its provider URL, and make your first request. Code samples are available in cURL as well as popular SDKs and programming languages.

Get Your Hyperliquid Endpoint

1

HyperCore Access

The quickstart below uses HyperEVM (/evm path), which is available on all plans including free trial.

HyperCore services have additional requirements:

• /info endpoint: available on all plans; 71 of 73 methods are natively supported (see method availability)
• /hypercore JSON-RPC and WebSocket: requires Build plan or higher
• gRPC streaming: requires Build plan or higher

Envie o seu primeiro pedido

Your endpoint is ready. Now, let's make your first call to the Hyperliquid blockchain. We’ll use the eth_blockNumber method, which returns the latest block number. Select your preferred language or SDK and follow the steps below to send your first request.

cURL

1

Verificar a instalação do cURL

Most *nix based systems have cURL support out of the box. Open your terminal and check the cURL version by running the command below:

curl --versão

2

Send a JSON-RPC request

In your terminal, copy and paste the following cURL command to retrieve the latest block number:

curl -X POST YOUR_QUICKNODE_ENDPOINT_URL/ \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

3

Sample Response

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x1234567"
}

SDK

1

Configure o seu projeto

First, verify Node.js is installed with node --version. If not installed, download it from https://nodejs.org. Then create a new directory and initialize a Node.js project:

mkdir hyperliquid-api-quickstart
cd hyperliquid-api-quickstart
npm init -y

2

Instale o SDK

Install the SDK package:

npm install @quicknode/sdk

3

Create your main file

Create an index.js file for your code:

touch index.js

4

Add this code to your index.js file

Copy and paste this code into your index.js file:

const { Core } = require('@quicknode/sdk');

const main = async () => {
  const core = new Core({
    endpointUrl: 'YOUR_QUICKNODE_ENDPOINT_URL/',
  });

  const blockNumber = await core.client.request({
    method: 'eth_blockNumber',
  });

  console.log('Block number:', parseInt(blockNumber, 16));
};

main();

5

Run your project

Execute your script to see the latest block number:

node index.js

4

Crie um script em Python (app.py)

Create a Python file with the following code:

import requests
import json

# Your Quicknode endpoint URL
endpoint_url = "YOUR_QUICKNODE_ENDPOINT_URL/"

# JSON-RPC request payload
payload = {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "eth_blockNumber",
    "params": []
}

# Make the request
response = requests.post(endpoint_url, json=payload)
result = response.json()

print("Latest block number (hex):", result["result"])
print("Latest block number (decimal):", int(result["result"], 16))

  body: JSON.stringify({
    jsonrpc: '2.0',
    method: 'eth_blockNumber',
    params: [],
    id: 1
  })
};

async function main() {
  try {
    const response = await fetch(url, options);
    const data = await response.json();
    console.log('Block Number (hex):', data.result);
    console.log('Block Number (decimal):', parseInt(data.result, 16));
