The quickest way to start building on Aleo with Quicknode is by sending a REST API request to your endpoint. In this guide, 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 Aleo Endpoint
Créer un Quicknode
Inscrivez-vous ici si ce n'est pas déjà fait.
Accédez à votre tableau de bord
Ouvrez le tableau de bord « Endpoints » dans le menu de la barre latérale gauche pour gérer tous vos points de terminaison blockchain.
Créer un nouveau endpoint
Click Create an Endpoint in the top-right corner, select Aleo as your blockchain, then select your preferred network
Copiez les URL de vos fournisseurs
Gardez l'URL HTTP à portée de main. Vous en aurez besoin dans les requêtes ci-dessous.

Envoyez votre première demande
Your endpoint is ready. Now, let's make your first call to the Aleo blockchain. We'll use the /block/height/latest endpoint, which returns the latest block height. Sélectionnez la langue ou SDK de votre choix SDK suivez les étapes ci-dessous pour envoyer votre première requête.
- cURL
- Node.js
Python
- Ruby
Vérifier l'installation de cURL
La plupart des systèmes basés sur *nix prennent en charge cURL dès leur installation. Ouvrez votre terminal et vérifiez la version de cURL en exécutant la commande ci-dessous :
curl --version
Send a REST API request
In your terminal, copy and paste the following cURL command to retrieve the latest block height:
curl -X GET YOUR_QUICKNODE_ENDPOINT_URL/v2/mainnet/block/height/latest \
-H 'Accept: application/json'

Configurez votre projet
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 aleo-api-quickstart
cd aleo-api-quickstart
npm init -y
Create your main file
Create an index.js file for your code:
touch index.js
Add this code to your index.js file
Copy and paste this code into your index.js file to get the latest block height:
const https = require('https');
const options = {
hostname: '{your-endpoint-name}.quiknode.pro',
path: '/{your-token}/v2/mainnet/block/height/latest',
method: 'GET',
headers: {
'Accept': 'application/json'
}
};
const req = https.request(options, (res) => {
let result = '';
res.on('data', (chunk) => {
result += chunk;
});
res.on('end', () => {
console.log('Latest block height:', result);
});
});
req.on('error', (error) => {
console.error('Error:', error);
});
req.end();
Run your code
Save the file and run it in your terminal:
node index.js
Check Python installation
Verify Python is installed on your system. Open your terminal and run:
python --version
Install required packages
Install the requests library if you haven't already:
pip installer requests
Create your Python script
Create a new Python file and add the following code to get the latest block height:
import requests
url = "YOUR_QUICKNODE_ENDPOINT_URL/v2/mainnet/block/height/latest"
headers = {
'Accept': 'application/json'
}
response = requests.request("GET", url, headers=headers)
print("Latest block height:", response.text)
Run your script
Save the file as aleo_block_height.py and run it:
python aleo_block_height.py
Vérifier l'installation de Ruby
Verify Ruby is installed on your system. Open your terminal and run:
ruby --version
Create your Ruby script
Create a new Ruby file and add the following code to get the latest block height:
require 'net/http'
require 'json'
uri = URI('YOUR_QUICKNODE_ENDPOINT_URL/v2/mainnet/block/height/latest')
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
request = Net::HTTP::Get.new(uri)
request['Accept'] = 'application/json'
response = http.request(request)
puts "Latest block height: #{response.body}"
Run your script
Save the file as aleo_block_height.rb and run it:
ruby aleo_block_height.rb
