The quickest way to start building on Celestia with Quicknode is by sending a REST API 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 other popular programming languages.
Get Your Celestia Endpoint
如需了解Quicknode 詳細操作指南，請參閱我們的 指南
發送您的第一項請求
Your endpoint is ready. Now, let's make your first call to the Celestia blockchain. We’ll use the 狀態 method, which retrieves Tendermint status including node info, pubkey, latest block hash, app hash, block height 以及 時間. Select your preferred language and follow the steps below to send your first request.
- cURL
- Node.js
Python- TypeScript
- Ruby
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 Status
To retrieve the node status, run the following cURL command:
curl --location 'YOUR_QUICKNODE_ENDPOINT_URL/status' \
--header 'accept: application/json'
設定您的專案
Create a directory and initialize a Node.js project:
mkdir celestia-js-quickstart
cd celestia-js-quickstart
npm init -y
Create app.js
Create a file named app.js to call the status endpoint:
const https = require('https');
const options = {
hostname: '{your-endpoint-name}.quiknode.pro',
path: '/{your-token}/status',
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('Status:', result);
});
});
req.on('error', (error) => {
console.error('Error:', error);
});
req.end();
Run
Execute your script:
node app.js
設定您的專案
為您的 Python 專案建立一個新目錄：
mkdir celestia-python-quickstart
cd celestia-python-quickstart
建立並啟用虛擬環境
建立一個虛擬環境來管理依賴項：
python3 -m venv venv
source venv/bin/activate
安裝請求
安裝 requests 函式庫，以便發送 HTTP 請求：
pip 安裝 requests
建立一個 Python 腳本（app.py）
Create a Python file to call the status endpoint:
import requests
url = "YOUR_QUICKNODE_ENDPOINT_URL/status"
headers = {
'accept': 'application/json'
}
response = requests.request("GET", url, headers=headers)
print('Status:')
print(response.text)
Run
Execute your script:
python app.py
設定您的專案
Create a directory and initialize a TypeScript project:
mkdir celestia-ts-quickstart
cd celestia-ts-quickstart
npm init -y
npm install typescript @types/node tsx
npx tsc --init
Create app.ts
Create a file named app.ts to call the status endpoint:
import https from 'https';
const options: https.RequestOptions = {
hostname: '{your-endpoint-name}.quiknode.pro',
path: '/{your-token}/status',
method: 'GET',
headers: {
'accept': 'application/json'
}
};
const req = https.request(options, (res) => {
let result = '';
res.on('data', (chunk: Buffer) => {
result += chunk.toString();
});
res.on('end', () => {
console.log('Status:', result);
});
});
req.on('error', (error: Error) => {
console.error('Error:', error);
});
req.end();
Run
Execute your script:
npx tsx app.ts
設定您的專案
為您的 Ruby 專案建立一個新目錄：
mkdir celestia-ruby-quickstart
cd celestia-ruby-quickstart
檢查 Ruby 的安裝狀況
請確認您的系統上已安裝 Ruby。若尚未安裝，請從 https://ruby-lang.org 進行安裝：
ruby --version
Create a Ruby script (app.rb)
Create an app.rb file to call the status endpoint:
require "uri"
require "net/http"
url = URI("YOUR_QUICKNODE_ENDPOINT_URL/status")
https = Net::HTTP.new(url.host, url.port)
https.use_ssl = true
request = Net::HTTP::Get.new(url)
request["accept"] = "application/json"
response = https.request(request)
puts "Status:"
puts response.read_body
執行該腳本
Execute your Ruby script:
ruby app.rb
