Answers a job's metric series — loss, throughput and each
validation suite's numbers as the executor reported them — one per name, each
point \[step, value, unix seconds].

## Request

1 field.

| Field | In   | Type   | Required | Description       |
| ----- | ---- | ------ | -------- | ----------------- |
| `id`  | path | string | yes      | ID names the job. |

## Response

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

`200` body — 3 fields.

| Field           | In   | Type                  | Always | Description                                  |
| --------------- | ---- | --------------------- | ------ | -------------------------------------------- |
| `data`          | body | train.series\[]       | —      | Data is one series per metric name.          |
| `data[].name`   | body | string                | —      | Name is the metric.                          |
| `data[].points` | body | number (double)\[]\[] | —      | Points are \[step, value, at] in step order. |

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.getTrainJobsByIdMetrics({ id: 'id' });
```

**.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).get_train_jobs_by_id_metrics(id='id')
```

**.go**

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

resp, _, err := client.TrainAPI.GetTrainJobsByIdMetrics(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::get_train_jobs_by_id_metrics(&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).getTrainJobsByIdMetrics();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/train/jobs/<id>/metrics \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**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.
