## Request

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

| Field             | In   | Type                | Required | Description                                                |
| ----------------- | ---- | ------------------- | -------- | ---------------------------------------------------------- |
| `id`              | path | string              | yes      | ID names the client.                                       |
| `id`              | body | string              | —        | ID names the client.                                       |
| `num_samples`     | body | integer (int64)     | —        | NumSamples is how many sequences to decode.                |
| `prompt`          | body | string              | —        | Prompt is a text prompt; exactly one of prompt and tokens. |
| `sampling_params` | body | any                 | —        | SamplingParams are the decoding parameters.                |
| `tokens`          | body | integer (uint32)\[] | —        | Tokens is a tokenized prompt.                              |

## Response

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

`200` body — 1 field.

| Field    | In   | Type | Always | Description |
| -------- | ---- | ---- | ------ | ----------- |
| `(body)` | body | any  | yes    |             |

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

## Examples

**CLI**

`hanzo` has no subcommand for this operation — the CLI serves only what cloud's live route table confirms. Use HTTP or an SDK.

**SDK**

**.ts**

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

const api = new TrainApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postTrainClientsByIdSample({ id: 'id', id: "<id>", num_samples: 0 });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = TrainApi(client).post_train_clients_by_id_sample(id='id', id="<id>", num_samples=0)
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new TrainApi(client).postTrainClientsByIdSample();
```

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/train/clients/<id>/sample \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "id": "<id>",
       "num_samples": 0
     }'
```

**MCP**

MCP declares no tool for **train** — `tools/list` on `https://api.hanzo.ai/v1/mcp` names the products it does reach. Use HTTP or an SDK.
