random - XRPL

Example code for the random JSON RPC method. Сomplete guide on how to use random JSON RPC in GetBlock Web3 documentation.

This method provides a random number to clients as a source of entropy for random number generation.

Parameters

• None

Returns

Field	Type	Description
random	string	256-bit random hex string

Request Example

cURL

curl --location --request POST 'https://shared.eu-central-1.getblock.io/<ACCESS_TOKEN>/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "random",
    "params": [{}],
    "id": "getblock.io"
}'

JavaScript (Axios)

const axios = require('axios');

const url = 'https://shared.eu-central-1.getblock.io/<ACCESS_TOKEN>/' 
const headers = {
    'Content-Type': 'application/json'
};

const payload = {
    jsonrpc: '2.0',
    method: 'random',
    params: [{}],
    id: 'getblock.io'
};

axios.post(url, payload, { headers })
    .then(response => console.log(response.data))
    .catch(error => console.error(error));

Python

import requests

url = "https://shared.eu-central-1.getblock.io/<ACCESS_TOKEN>/"
headers = {
    "x-api-key": "YOUR-API-KEY",
    "Content-Type": "application/json"
}

payload = {
    "jsonrpc": "2.0",
    "method": "random",
    "params": [{}],
    "id": "getblock.io"
}

response = requests.post(url, headers=headers, json=payload)
print(response.json())

Rust

use reqwest::Client;
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();
    
    let payload = json!({

        "method": "random",
        "params": [{}],
        "id": "getblock.io"
    });

    let response = client
        .post("https://shared.eu-central-1.getblock.io/<ACCESS_TOKEN>/")
        .header("x-api-key", "YOUR-API-KEY")
        .header("Content-Type", "application/json")
        .json(&payload)
        .send()
        .await?;

    let result: serde_json::Value = response.json().await?;
    println!("{:#?}", result);
    
    Ok(())
}
