## Response

```json
{

        "solana-core": "2.3.6"
    }
}
```

## Response Parameters

| Parameter | Type   | Description                                                           |
| --------- | ------ | --------------------------------------------------------------------- |
| jsonrpc   | string | JSON-RPC protocol version ("2.0")                                     |
| id        | string | Request identifier matching the request                               |
| result    | object | Object holding the node's software version and feature set identifier |

### Result Object

| Field       | Type   | Description                                        |
| ----------- | ------ | -------------------------------------------------- |
| solana-core | string | Validator software version string                  |
| feature-set | number | Unique identifier of the node's active feature set |

## Use Cases

* **Compatibility Gates**: Require a minimum node version before using a newer RPC option
* **Upgrade Tracking**: Confirm an endpoint has been upgraded after a scheduled release
* **Feature Detection**: Match the feature set against activation records before relying on a feature
* **Support Reporting**: Include node version when reporting unexpected RPC behaviour

## Error Handling

| Error Code | Message           | Description                                     |
| ---------- | ----------------- | ----------------------------------------------- |
| -32603     | Internal error    | Node failed to read the requested cluster state |
| -32005     | Node is unhealthy | The node has fallen behind the cluster tip      |
