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

1

创建一个 Quicknode 账户

如果您尚未注册，请在此注册。

2

前往您的仪表盘

从左侧边栏菜单中打开“端点”仪表板，以管理您所有的区块链端点

3

创建一个新的端点

Click Create an Endpoint in the top-right corner, select Aleo as your blockchain, then select your preferred network

4

复制您的服务商 URL

请将该 HTTP URL 备好。您将在下文的请求中用到它。

发送您的第一个请求

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. 选择您首选的语言或 SDK，并按照以下步骤发送您的第一个请求.

cURL

1

检查 cURL 的安装情况

大多数基于 *nix 的系统默认都支持 cURL。打开终端，运行以下命令检查 cURL 的版本：

curl --version

2

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'

Node.js

1

设置您的项目

首先，使用 `node --version` 命令验证 Node.js 是否已安装。如果尚未安装，请从 https://nodejs.org 下载。然后创建一个新目录并初始化一个 Node.js 项目：

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

2

创建主文件

为您的代码创建一个 index.js 文件：

touch index.js

3

将此代码添加到你的 index.js 文件中

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();

4

Run your code

Save the file and run it in your terminal:

node index.js

Python

1

Check Python installation

Verify Python is installed on your system. Open your terminal and run:

python --version

2

Install required packages

Install the requests library if you haven't already:

pip 安装 requests

3

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)

4

Run your script

Save the file as aleo_block_height.py and run it:

python aleo_block_height.py

Ruby

1

检查 Ruby 安装情况

Verify Ruby is installed on your system. Open your terminal and run:

ruby --version

2

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}"

3

Run your script

Save the file as aleo_block_height.rb and run it:

ruby aleo_block_height.rb
