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

發送您的第一個請求
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
檢查 cURL 的安裝狀況
大多數基於 *nix 的系統預設即支援 cURL。請開啟終端機，並執行以下指令以檢查 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'

設定您的專案
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();
Run
Execute your script:
node app.js
