| **Address**   | `https://api.hanzo.ai/v1/index/version` |
| **Method**    | `GET`                                   |

| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`  |

Identifies the search implementation answering.

Reports the dialect's version shape with `commitSha` naming this
implementation rather than a Meilisearch build, so a client that logs the
version records which server answered instead of implying a release of
software this is not. It requires no principal and reads no tenant data.

## Request

`GET /v1/index/version` takes no parameters and no body — the credential is the whole request.

## Response

| Status    | Body               | Meaning |
| --------- | ------------------ | ------- |
| `200`     | index.indexVersion | ok      |
| `default` | problem-details    | refused |

`200` body — 3 fields.

| Field        | In   | Type   | Always | Description                                                                                                                                                                  |
| ------------ | ---- | ------ | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `commitDate` | body | string | —      | CommitDate is empty here: this surface is a dialect implementation, not a build of Meilisearch, so there is no upstream commit to date.                                      |
| `commitSha`  | body | string | —      | CommitSha names the implementation (`hanzo-cloud`) rather than a build hash, so a client logging it records which server answered instead of implying a Meilisearch release. |
| `pkgVersion` | body | string | —      | PkgVersion is this dialect implementation's own version.                                                                                                                     |

Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo index version
```

**SDK**

**.ts**

```ts
import { Configuration, IndexApi } from 'hanzoai';

const api = new IndexApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.getIndexVersion();
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import IndexApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = IndexApi(client).get_index_version()
```

**.go**

```go
cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.IndexAPI.GetIndexVersion(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, index_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = index_api::get_index_version(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.IndexApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new IndexApi(client).getIndexVersion();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/index/version \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

Tool `index`, op `get_index_version` — POST the JSON-RPC envelope to `https://api.hanzo.ai/v1/mcp`.

```bash
curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "index",
         "arguments": {
           "op": "get_index_version",
           "input": {}
         }
       }
     }'
```
