# RPC Access

This uses a demo network, which is deployed for all users to access the Polygon CDK network RPC. You can use the same thing with the newly deployed network.

**Step 1: Register/Login -** Create a new account or log in to an existing account on the [Zeeve Platform](https://app.zeeve.io/auth/signup).

**Step 2: Zeeve Dashboard -** On the Zeeve platform dashboard click on the **Polygon CDK** option under the **APPCHAINS & ROLLUPS** section available in the left sidebar**.** This will show your deployed Polygon CDK network.

**Step 3: Demo Network Card -** Once you're on the page, you’ll see a network card labeled “**Demo**.” This is a pre-deployed network accessible to all users in Zeeve. Click on the **View** button on the Demo card.

**Step 4: My Nodes -** You will land on the overview tab, where you can see the overview of the network, and navigate to the **My Nodes** tab.

**Step 5: Node List -** Here, you can see the deployed node in the Polygon CDK and navigate to the **RPC nodes.**

**Step 6: RPC Node -** Once you are in the RPC node tab, click on the **View Details** icon below Actions. It will open the RPC node details page. Here you can see the RPC node details like **Node General Info**, **RPC Endpoint, Configurations**, and **Cloud Infra.**

**Step 7: RPC Endpoint -** in this section, You will get the endpoint for Polygon CDK RPC. You can use the polygon CDK JSON RPC methods with this.

**Step 8: RPC Username and Password -** You can find the RPC username in the RPC endpoint section. The password will be the same as you set during the network creation time.

**RPC calls using curl -**

```bash
# curl to get the polygon Cdk block height
curl https://demouser:demopass@rpcnode.demo-vali-02aa6b.zeeve.net/rpc \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}'
```

**RPC calls using WebSocket -**

```bash
# Web socket to get the block number
npx wscat -c wss://demouser:demopass@rpcnode.demo-vali-02aa6b.zeeve.net/ws
# calling the JSON-RPC method after the WebSocket connection
{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}
```
