Answers which units can reach a site soonest. Distance is a great-circle
haversine over the units' last reported positions, and an available unit sorts
ahead of a busy one at any distance — a controller asking for the nearest unit
is asking for the nearest free one.

## Request

2 fields.

| Field   | In    | Type    | Required | Description                                         |
| ------- | ----- | ------- | -------- | --------------------------------------------------- |
| `site`  | query | string  | —        | Site is the site to measure from, by document name. |
| `limit` | query | integer | —        | Limit caps how many units come back.                |

## Response

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

`200` body — 4 fields.

| Field         | In   | Type                    | Always | Description                                                           |
| ------------- | ---- | ----------------------- | ------ | --------------------------------------------------------------------- |
| `data`        | body | patrol.patrolNearest\[] | —      | Data is the closest units, available ones first and then by distance. |
| `data[].eta`  | body | integer (int64)         | —      | Eta is the minutes the drive would take at the planning speed.        |
| `data[].km`   | body | number (double)         | —      | Km is the great-circle distance to the site in kilometres.            |
| `data[].unit` | body | string                  | —      | Unit is the unit's call sign.                                         |

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

const { data } = await api.getPatrolUnitNear();
```

**.py**

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

```

**.go**

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

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

**.rs**

```rust

```

**.java**

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