Executing the Node RPC Endpoint with TypeScript

1. As an example, execute the Soneium Minato Node RPC endpoint:
   1. index.ts

const API_URL = "https://soneium-minato.rpc.scs.startale.com"; // If Astar or AstarZK is used, this should also be changed.
const API_KEY = "YOUR_API_KEY"; // // Replace with your Node RPC API Key.

// RPC request payload
const payload = {
  id: 1,
  jsonrpc: "2.0",
  method: "eth_blockNumber",
};

async function getBlockNumber() {
  const response = await fetch(`${API_URL}?apikey=${API_KEY}`, {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify(payload),
  });

  if (!response.ok) {
    throw new Error(`HTTP error! status: ${response.status}`);
  }

  const data = await response.json();

  console.log(`Latest block number: ${parseInt(data.result, 16)}`);
}

// Execute the function
getBlockNumber();

2. Run it using Node.js.

npx tsc index.ts

node index.ts

3. The console should display the latest block number.

Latest block number: 4745445

4. Congratulations!
   You have successfully sent your first request to the SCS Node RPC API endpoint.

How to check the status

1. On the RPC endpoints page, click the Detail button for the desired endpoint to navigate to Detail page.
2. You can view the endpoint's statistics on the endpoint page under usage tab.
