Returns the `CHAIN_ID` of the specified network. This is represented as a `String`.

See table below for the `CHAIN_ID` for different chains:

| Chain(s)              | `CHAIN_ID` |
| --------------------- | ---------- |
| **Zilliqa mainnet**   | `1`        |
| **Developer testnet** | `333`      |
| **Isolated server**   | `222`      |

**NOTE:** `CHAIN_ID` from `2` to `9` are reserved for Zilliqa Core use.

        "method": "GetNetworkId",
        "params": [""]
    }' -H "Content-Type: application/json" -X POST "https://api.zilliqa.com/"
    ```

=== "Node.js"

    ```js
    const NetworkId = await zilliqa.network.GetNetworkId();
    console.log(NetworkId);
    ```

    ```java
    public class App {
        public static void main(String[] args) throws IOException {
            HttpProvider client = new HttpProvider("https://api.zilliqa.com");
            Rep<String> networkId = client.getNetworkId();
            System.out.println(new Gson().toJson(networkId));
        }
    }
    ```

    # EITHER
    chain.set_active_chain(chain.MainNet)
    network_id = chain.active_chain.api.GetNetworkId()
    print(network_id)

    # OR
    new_api = ZilliqaAPI(endpoint="https://api.zilliqa.com")
    network_id = new_api.GetNetworkId()
    print(network_id)
    ```

=== "Go"

    func GetNetworkId() {
        provider := NewProvider("https://api.zilliqa.com/")
        response := provider.GetNetworkId()
        result, _ := json.Marshal(response)
