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

1

Criar uma Quicknode

Inscreve-te aqui, se ainda não o fizeste.

2

Aceda ao seu painel de controlo

Open the Endpoints dashboard from the left sidebar menu to manage all your blockchain endpoints

3

Criar um novo endpoint

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

4

Copie os URLs do seu fornecedor

Tenha a URL HTTP à mão. Vai precisar dela nas solicitações que se seguem.

Envie o seu primeiro pedido

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

1

Verificar a instalação do cURL

Most *nix based systems have cURL support out of the box. Open your terminal and check the cURL version by running the command below:

curl --versão

2

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'

Node.js

1

Configure o seu projeto

Crie um diretório e inicialize um projeto Node.js:

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

2

Criar o ficheiro 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();

Correr

Execute o seu script:

node app.js

Python

1

Configure o seu projeto

Crie um novo diretório para o seu projeto em Python:

mkdir stacks-python-quickstart
cd stacks-python-quickstart

2

Criar e ativar um ambiente virtual

Criar um ambiente virtual para gerir dependências:

python3 -m venv venv
source venv/bin/activate

3

Pedidos de instalação

Instale a biblioteca `requests` para efetuar pedidos HTTP:

pip instalar requests

4

Crie um script em Python (app.py)

Create a Python file with the following code:

import requests

url = "YOUR_QUICKNODE_ENDPOINT_URL/v2/info"

headers = {
  'Content-Type': 'application/json'
}

response = requests.request("GET", url, headers=headers)

print(response.text)

5

Executar o script
