## Connecting to Your Node

Once your dedicated BNB Chain node is provisioned, you will receive a private endpoint URL. The endpoint follows the same API structure as the official BSC RPC.

### Authentication

Your node URL includes your license key as a query parameter:

```
https://bnb-{region}.rpc.orbitflare.com?api_key=YOUR_LICENSE_KEY
```

### Making RPC Calls

BNB Chain uses the same JSON-RPC 2.0 format as Ethereum. Pass `Content-Type: application/json` with a POST body:

<CodeGroup>
  ```bash cURL theme={null}
  curl -X POST "https://bnb-fra.rpc.orbitflare.com?api_key=YOUR_LICENSE_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "jsonrpc": "2.0",
      "method": "eth_blockNumber",
      "params": [],
      "id": 1
    }'
  ```

  ```javascript JavaScript theme={null}
  const response = await fetch(
    "https://bnb-fra.rpc.orbitflare.com?api_key=YOUR_LICENSE_KEY",
    {
      method: "POST",
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify({
        jsonrpc: "2.0",
        method: "eth_blockNumber",
        params: [],
        id: 1,
      }),
    }
  );
  const data = await response.json();
  console.log("Latest block:", parseInt(data.result, 16));
  ```

  ```python Python theme={null}
  import requests

  response = requests.post(
      "https://bnb-fra.rpc.orbitflare.com?api_key=YOUR_LICENSE_KEY",
      headers={"Content-Type": "application/json"},
      json={
          "jsonrpc": "2.0",
          "method": "eth_blockNumber",
          "params": [],
          "id": 1,
      },
  )
  data = response.json()
  print("Latest block:", int(data["result"], 16))
  ```
</CodeGroup>

### WebSocket Subscriptions

Real-time subscriptions use the `wss://` scheme with the same endpoint:

```javascript theme={null}
const ws = new WebSocket(
  "wss://bnb-fra.rpc.orbitflare.com?api_key=YOUR_LICENSE_KEY"
);

ws.on("open", () => {
  ws.send(JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "eth_subscribe",
    params: ["newHeads"],
  }));
});

ws.on("message", (data) => {
  const msg = JSON.parse(data);
  console.log("New block header:", msg.params?.result);
});
```

### Supported Methods

Your dedicated node exposes the complete BNB Chain / BSC JSON-RPC API including:

| Category         | Methods                                                                           |
| ---------------- | --------------------------------------------------------------------------------- |
| **Blocks**       | `eth_blockNumber`, `eth_getBlockByHash`, `eth_getBlockByNumber`                   |
| **Transactions** | `eth_sendRawTransaction`, `eth_getTransactionByHash`, `eth_getTransactionReceipt` |
| **Accounts**     | `eth_getBalance`, `eth_getCode`, `eth_getStorageAt`, `eth_getTransactionCount`    |
| **Contracts**    | `eth_call`, `eth_estimateGas`, `eth_getLogs`                                      |
| **Network**      | `net_version`, `eth_chainId`, `eth_gasPrice`, `eth_feeHistory`                    |
| **WebSocket**    | `eth_subscribe` (newHeads, logs, newPendingTransactions)                          |

<Note>
  BNB Chain uses `chainId: 56` for mainnet and `chainId: 97` for testnet (BSC Testnet). Your dedicated node connects to mainnet by default.
