# getIdentity - Solana

This method returns the identity Pubkey of the node serving the request. The identity keypair signs the node's gossip messages and, for validators, its blocks.

## Parameters

This method does not accept any parameters.

## Request

--data-raw '{
    "jsonrpc": "2.0",
    "method": "getIdentity",

```javascript
const { Connection } = require('@solana/web3.js');

const connection = new Connection('https://go.getblock.io/<ACCESS-TOKEN>/', 'confirmed');

const { result } = await connection._rpcRequest('getIdentity', []);

console.log(result.identity);
```

{% endcode %}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();

    let response = client
        .post("https://go.getblock.io/<ACCESS-TOKEN>/")

## Response

```json
{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": {
        "identity": "dv1ZAGvdsz5hHLwWXsVnM94hWf1pjbKVau1QVkaMJ92"
    }
}
```

## Response Parameters

| Parameter | Type   | Description                                  |
| --------- | ------ | -------------------------------------------- |
| jsonrpc   | string | JSON-RPC protocol version ("2.0")            |
| id        | string | Request identifier matching the request      |
| result    | object | Object containing the node's identity Pubkey |

### Result Object

| Field    | Type   | Description                                           |
| -------- | ------ | ----------------------------------------------------- |
| identity | string | Base58-encoded identity Pubkey of the responding node |

## Use Cases

* **Endpoint Fingerprinting**: Identify which backend node served a request behind a load balancer
* **Sticky Debugging**: Correlate inconsistent responses with a specific node identity
* **Fleet Inventory**: Map dedicated node endpoints to their identity keys
* **Support Diagnostics**: Attach node identity to bug reports about response discrepancies

## 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/getidentity-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.
