The quickest way to start building on XRPL 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 other popular programming languages.
Get Your XRPL Endpoint
Créer un Quicknode
Inscrivez-vous ici si ce n'est pas déjà fait.
Accédez à votre tableau de bord
Ouvrez le tableau de bord « Endpoints » dans le menu de la barre latérale gauche pour gérer tous vos points de terminaison blockchain.
Créer un nouveau endpoint
Click Create an Endpoint in the top-right corner, select XRPL as your blockchain, then select your preferred network
Copiez les URL de vos fournisseurs
Gardez l'URL HTTP à portée de main. Vous en aurez besoin dans les requêtes ci-dessous.

Envoyez votre première demande
Your endpoint is ready. Now, let's make your first call to the XRPL blockchain. We'll use the frais method, which retrieves current fee information from the network. Select your preferred language and follow the steps below to send your first request.
- cURL
- Node.js
Python- Ruby
Vérifier l'installation de cURL
La plupart des systèmes basés sur *nix prennent en charge cURL dès leur installation. Ouvrez votre terminal et vérifiez la version de cURL en exécutant la commande ci-dessous :
curl --version
Envoyer une requête JSON-RPC
In your terminal, copy and paste the following cURL command to retrieve current fee information:
curl YOUR_QUICKNODE_ENDPOINT_URL/ \
-X POST \
-H "Content-Type: application/json" \
--data '{
"method": "fee",
"params": [{}],
« id » : 1,
"jsonrpc": "2.0"
}'
Exemple de réponse
{
"id": 1,
"status": "success",
"type": "response",
"result": {
"current_ledger_size": "56",
"current_queue_size": "0",
"drops": {
"base_fee": "10",
"median_fee": "5000",
"minimum_fee": "10",
"open_ledger_fee": "10"
},
"expected_ledger_size": "55",
"ledger_current_index": 75708765,
"levels": {
"median_level": "128000",
"minimum_level": "256",
"open_ledger_level": "256",
"reference_level": "256"
},
"max_queue_size": "1100"
}
}
Configurez votre projet
First, verify Node.js is installed with node --version. If not installed, download it from https://nodejs.org. Then create a new directory and initialize a Node.js project:
mkdir xrpl-api-quickstart
cd xrpl-api-quickstart
npm init -y
Create your main file
Create an index.js file for your code:
touch index.js
Add this code to your index.js file
Copy and paste this code into your index.js file:
const https = require('https');
const data = JSON.stringify({
method: "fee",
params: [{}],
id: 1,
jsonrpc: "2.0"
});
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 responseData = '';
res.on('data', (chunk) => {
responseData += chunk;
});
res.on('end', () => {
console.log('XRPL Fee Information:');
console.log(JSON.stringify(JSON.parse(responseData), null, 2));
});
});
req.on('error', (error) => {
console.error('Error:', error);
});
req.write(data);
req.end();
Exécutez le script
Execute your Node.js script to retrieve fee information:
node index.js
Configurez votre projet
Create a new directory for your project:
mkdir xrpl-api-quickstart
cd xrpl-api-quickstart
Créer et activer un environnement virtuel
Créer un environnement virtuel pour gérer les dépendances :
python3 -m venv venv
source venv/bin/activate
Install required packages
Install the requests library:
pip installer requests
Create a Python script (main.py)
Create a main.py file with the following code:
import requests
import json
url = "YOUR_QUICKNODE_ENDPOINT_URL/"
payload = {
"method": "fee",
"params": [{}],
"id": 1,
"jsonrpc": "2.0"
}
headers = {
'Content-Type': 'application/json'
}
try:
response = requests.post(url, json=payload, headers=headers)
response.raise_for_status()
data = response.json()
print("XRPL Fee Information:")
print(json.dumps(data, indent=2))
except requests.exceptions.RequestException as e:
print(f"Error making request: {e}")
except json.JSONDecodeError as e:
print(f"Error parsing JSON: {e}")
Exécutez le script
Execute your Python script to retrieve fee information:
python main.py
Configurez votre projet
Créez un nouveau répertoire pour votre projet Ruby :
mkdir xrpl-ruby-quickstart
cd xrpl-ruby-quickstart
Check Ruby Installation
Vérifiez que Ruby est bien installé sur votre système. Si ce n'est pas le cas, installez-le à partir du site https://ruby-lang.org :
ruby --version
Créer un script Ruby (main.rb)
Créez un fichier main.rb contenant le code suivant :
require 'uri'
require 'net/http'
require 'json'
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 = {
method: "fee",
params: [{}],
id: 1,
jsonrpc: "2.0"
}.to_json
begin
response = https.request(request)
if response.is_a?(Net::HTTPSuccess)
data = JSON.parse(response.body)
puts 'XRPL Fee Information:'
puts JSON.pretty_generate(data)
else
puts "HTTP Error: #{response.code} - #{response.message}"
fin
rescue JSON::ParserError => e
puts "JSON parsing error: #{e.message}"
rescue => e
puts "Error: #{e.message}"
fin
Exécutez le script
Execute your Ruby script to retrieve fee information:
ruby main.rb
