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
Criar uma Quicknode
Inscreve-te aqui, se ainda não o fizeste.
Aceda ao seu painel de controlo
Open the Endpoints dashboard from the left sidebar menu to manage all your blockchain endpoints
Criar um novo endpoint
Click Create an Endpoint in the top-right corner, select Aleo as your blockchain, then select your preferred network
Copie os URLs do seu fornecedor
Tenha a URL HTTP à mão. Vai precisar dela nas solicitações que se seguem.

Envie o seu primeiro pedido
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. Select your preferred language or SDK and follow the steps below to send your first request.
- cURL
- Node.js
Python- Ruby
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
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'

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 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 instalar 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
Verificar a instalação do Ruby
Verify Ruby is installed on your system. Open your terminal and run:
ruby --versão
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
