The quickest way to start building on Stacks with Quicknode is by sending a 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 Stacks Endpoint

发送您的第一个请求
Your endpoint is ready. Now, let's make your first call to the Stacks blockchain. We’ll use the /v2/info endpoint to fetch information about the Stacks Core API. Select your preferred language or SDK below and follow the steps.
- cURL
- Node.js
Python
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
Get Server Info
To run the cURL request, open a terminal window and paste the following code to retrieve the server information.
curl --location 'YOUR_QUICKNODE_ENDPOINT_URL/v2/info' \
--header 'Content-Type: application/json'

设置您的项目
Create a directory and initialize a Node.js project:
mkdir stacks-js-quickstart
cd stacks-js-quickstart
npm init -y
Create app.js
Add the code into your JavaScript file and execute the file in your terminal with the `node fileName.js` to retrieve the server information.
const https = require('https');
const options = {
hostname: '{your-endpoint-name}.quiknode.pro',
path: '/{your-token}/v2/info',
method: 'GET',
headers: {
'Content-Type': 'application/json'
}
};
const req = https.request(options, (res) => {
let result = '';
res.on('data', (chunk) => {
result += chunk;
});
res.on('end', () => {
console.log(result);
});
});
req.on('error', (error) => {
console.error('Error:', error);
});
req.end();
运行
Execute your script:
node app.js
设置您的项目
为您的 Python 项目创建一个新目录：
mkdir stacks-python-quickstart
cd stacks-python-quickstart
创建并激活虚拟环境
创建一个虚拟环境来管理依赖项：
python3 -m venv venv
source venv/bin/activate
安装请求
安装 requests 库以进行 HTTP 请求：
pip 安装 requests
编写一个 Python 脚本（app.py）
创建一个包含以下代码的 Python 文件：
import requests
url = "YOUR_QUICKNODE_ENDPOINT_URL/v2/info"
headers = {
'Content-Type': 'application/json'
}
response = requests.request("GET", url, headers=headers)
print(response.text)
运行该脚本
运行您的 Python 脚本：
python app.py
