## Response

```json
{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": {

        "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      |

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.getblock.io/api-reference/solana-sol/getversion-solana.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
