The quickest way to start building on Zcash with Quicknode is by sending a JSON-RPC 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 Zcash Endpoint
Criar uma Quicknode
Inscreve-te aqui, se ainda não o fizeste.
Aceda ao seu painel de controlo
Open the Endpoints dashboard from the left sidebar menu to manage all your blockchain endpoints
Criar um novo endpoint
Click Create an Endpoint in the top-right corner, select Zcash as your blockchain, then select your preferred network
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 Zcash blockchain. We'll use the getblock method, which retrieves detailed information about a specific block by its hash. Select your preferred language or SDK and follow the steps below to send your first request.
- cURL
Python- JavaScript
- Ruby
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
Send a JSON-RPC request
In your terminal, copy and paste the following cURL command to retrieve block information:
curl YOUR_QUICKNODE_ENDPOINT_URL/ \
-X POST \
-H "Content-Type: application/json" \
--data '{"id": 1, "jsonrpc": "2.0", "method": "getblock", "params": ["00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09"]}'

Configure o seu projeto
Crie um novo diretório para o seu projeto em Python:
mkdir zcash-python-quickstart
cd zcash-python-quickstart
Criar e ativar um ambiente virtual
Criar um ambiente virtual para gerir dependências:
python3 -m venv venv
source venv/bin/activate
Pedidos de instalação
Instale a biblioteca `requests` para efetuar pedidos HTTP:
pip instalar requests
Crie um script em Python (app.py)
Create a Python file with the following code:
import requests
import json
# Your Quicknode endpoint URL
url = "YOUR_QUICKNODE_ENDPOINT_URL/"
# JSON-RPC request payload for getblock
payload = json.dumps({
"id": 1,
"jsonrpc": "2.0",
"method": "getblock",
"params": ["00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09"]
})
headers = {
'Content-Type': 'application/json'
}
# Make the request
response = requests.request("POST", url, headers=headers, data=payload)
result = response.json()
print("Block information:")
print(json.dumps(result, indent=2))
Executar o script
Execute your Python script:
python app.py
Configure o seu projeto
Create a new directory and initialize a Node.js project:
mkdir zcash-js-quickstart
cd zcash-js-quickstart
npm init -y
Create a JavaScript file (app.js)
Create an app.js file with the following code (using native https module):
const https = require('https');
// Your Quicknode endpoint URL
const data = JSON.stringify({
"id": 1,
"jsonrpc": "2.0",
"method": "getblock",
"params": ["00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09"]
});
const options = {
hostname: '{your-endpoint-name}.quiknode.pro',
path: '/{your-token}/',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': data.length
}
};
const req = https.request(options, (res) => {
let result = '';
res.on('data', (chunk) => {
result += chunk;
});
res.on('end', () => {
console.log('Block information:');
console.log(JSON.parse(result));
});
});
req.on('error', (error) => {
console.error('Error:', error);
});
req.write(data);
req.end();
Executar o script
Execute your JavaScript script:
node app.js
Configure o seu projeto
Crie um novo diretório para o seu projeto Ruby:

cd zcash-ruby-quickstart
Verificar a instalação do Ruby
Verifique se o Ruby está instalado no seu sistema. Caso contrário, instale-o a partir de https://ruby-lang.org:
ruby --versão
Create a Ruby script (main.rb)
Create a main.rb file with the following code:
require "uri"
require "json"
require "net/http"
# Your Quicknode endpoint URL
url = URI("YOUR_QUICKNODE_ENDPOINT_URL/")
https = Net::HTTP.new(url.host, url.port)
https.use_ssl = true
request = Net::HTTP::Post.new(url)
request["Content-Type"] = "application/json"
request.body = JSON.dump({
"id": 1,
"jsonrpc": "2.0",
"method": "getblock",
"params": ["00000000c937983704a73af28acdec37b049d214adbda81d7e2a3dd146f6ed09"]
})
response = https.request(request)
result = JSON.parse(response.read_body)
puts "Block information:"
puts JSON.pretty_generate(result)
Executar o script
Execute your Ruby script to retrieve block information:
