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

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 Celestia 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 Celestia blockchain. We’ll use the 状态 method, which retrieves Tendermint status including node info, 公钥, latest block hash, app hash, block height 以及 时间. Select your preferred language and follow the steps below to send your first request.

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

Get Status

To retrieve the node status, run the following cURL command:

curl --location 'YOUR_QUICKNODE_ENDPOINT_URL/status' \
--header 'accept: application/json'

Node.js

1

设置您的项目

Create a directory and initialize a Node.js project:

mkdir celestia-js-quickstart
cd celestia-js-quickstart
npm init -y

2

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();

3

运行

Execute your script:

node app.js

Python

1

设置您的项目

为您的 Python 项目创建一个新目录：

mkdir celestia-python-quickstart
cd celestia-python-quickstart

2

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

3

安装请求

安装 requests 库以进行 HTTP 请求：

pip 安装 requests

4

编写一个 Python 脚本（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)

5

运行

Execute your script:

python app.py

TypeScript

1

设置您的项目

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

2

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();

3

运行

Execute your script:

npx tsx app.ts

Ruby

1

设置您的项目

为您的 Ruby 项目创建一个新目录：

mkdir celestia-ruby-quickstart
cd celestia-ruby-quickstart

2

检查 Ruby 安装情况

请确认您的系统上已安装 Ruby。如果尚未安装，请从 https://ruby-lang.org 安装：

ruby --version

3

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

4

运行该脚本

Execute your Ruby script:

ruby app.rb
