## Request

1 field, body `application/json` (required).

## Response

| Status    | Body            | Meaning |
| --------- | --------------- | ------- |
| `200`     | train.Capture   | ok      |
| `default` | problem-details | refused |

`200` body — 2 fields.

| Field            | In   | Type            | Always | Description                                                                          |

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

**.rs**

```rust

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

**.java**

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