| **Address**   | `https://api.hanzo.ai/v1/o11y/service_accounts/{id}/keys` |
| **Method**    | `POST`                                                    |
| **Operation** | `CreateServiceAccountKey`                                 |

Mints an API key for a service account and answers
the key's id and its secret — the one time the secret is ever shown.

ExpiresAt is a unix timestamp in seconds; zero means the key never expires,
and a timestamp in the past is refused.

## Request

3 fields, body `application/json` (required).

| Field       | In   | Type             | Required | Description                                                                                                         |
| ----------- | ---- | ---------------- | -------- | ------------------------------------------------------------------------------------------------------------------- |
| `id`        | path | string           | yes      |                                                                                                                     |
| `expiresAt` | body | integer (uint64) | —        | ExpiresAt is when the key stops working, as a unix timestamp in seconds.                                            |
| `name`      | body | string           | —        | Name is the key's name: a lowercase letter followed by lowercase letters, digits or hyphens, at most 80 characters. |

## Response

| Status    | Body                     | Meaning           |
| --------- | ------------------------ | ----------------- |

`201` body — 4 fields.

| Field      | In   | Type                  | Always | Description                                               |

| `data.id`  | body | string                | —      | ID is the key id.                                         |
| `data.key` | body | string                | —      | Key is the secret the service account authenticates with. |
| `status`   | body | string                | —      | Status is "success".                                      |

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

## Examples

**CLI**

```bash
hanzo o11y service_accounts keys create <id>
```

**SDK**

**.ts**

```ts
import { Configuration, O11yApi } from 'hanzoai';

const api = new O11yApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.createServiceAccountKey({ id: 'id', expiresAt: 0, name: "<name>" });
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import O11yApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = O11yApi(client).create_service_account_key(id='id', expires_at=0, name="<name>")
```

**.go**

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

resp, _, err := client.O11yAPI.CreateServiceAccountKey(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, o11y_api};

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

let result = o11y_api::create_service_account_key(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.O11yApi;

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

var result = new O11yApi(client).createServiceAccountKey();
```

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/o11y/service_accounts/<id>/keys \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "expiresAt": 0,
       "name": "<name>"
     }'
```

**MCP**

MCP reaches **o11y** through the `o11y` tool, which names its 307 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them:

```bash
curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_o11y_autocomplete_aggregate_attributes"
         }
       }
     }'
```
