⚡ How to Issue an API Key for Node RPC Access

  1. Visit the RPC endpoints page.
  2. Click the Create New Endpoint button.
  3. Configure your new endpoint:
    • Select a Chain from the dropdown.
    • Choose the desired Network.
    • Add a Name and (optionally) a Description.
  4. Click Create endpoint.

✅ Your RPC endpoint will now appear in the list of available endpoints.

How to Test API Endpoints

Check Your API Key​

You can find your API key in two places:

From the RPC Endpoints Page​

  • Click the Copy API Key button.

From the Endpoint Detail Page​

  • Click on your endpoint to open its detail page.
  • Then click Copy API Key.
  • You can also click Configure to view the HTTPS and WSS endpoints.

Execute the Node RPC with TypeScript

Here’s an example using the Soneium Minato Node RPC endpoint:

const API_URL = "https://soneium-minato.rpc.scs.startale.com"; // Replace if using Astar or AstarZK
const API_KEY = "YOUR_API_KEY"; // Replace with your actual API Key

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)}`);
}

getBlockNumber();

Run It Using Node.js​

npx tsc index.ts
node index.ts

Expected output:​

Latest block number: 4745445
Congratulations!

You’ve successfully sent your first request to the SCS Node RPC API endpoint.


How to Check Endpoint Status​

Go to the RPC endpoints page.

Click the Detail button next to your endpoint.

Under the Usage tab, you’ll find detailed statistics and request metrics.
