## Get feature by type and ID

`elements.lookup()  -> GeoJsonFeature`

**post** `/api/v1/features/lookup`

Get feature by type and ID

### Returns

- `class GeoJsonFeature: …`

  GeoJSON Feature representing an OSM element. Tags from the original OSM element are flattened directly into `properties` (not nested under a `tags` key). Metadata fields `@type` and `@id` identify the OSM element type and ID within properties.

  - `geometry: GeoJsonGeometry`

    GeoJSON Geometry object per RFC 7946. Coordinates use [longitude, latitude] order. 3D coordinates [lng, lat, elevation] are used for elevation endpoints.

    - `coordinates: Union[List[float], List[List[float]], List[List[List[float]]], List[List[List[List[float]]]]]`

      Coordinates array. Nesting depth varies by geometry type: Point = [lng, lat], LineString = [[lng, lat], ...], Polygon = [[[lng, lat], ...], ...], etc.

      - `List[float]`

        [longitude, latitude] or [longitude, latitude, elevation]

      - `List[List[float]]`

        Array of [lng, lat] positions

      - `List[List[List[float]]]`

        Array of linear rings / line strings

      - `List[List[List[List[float]]]]`

        Array of polygons

    - `type: Literal["Point", "LineString", "Polygon", 3 more]`

      Geometry type

      - `"Point"`

      - `"LineString"`

      - `"Polygon"`

      - `"MultiPoint"`

      - `"MultiLineString"`

      - `"MultiPolygon"`

  - `properties: Dict[str, object]`

    OSM tags flattened as key-value pairs, plus `@type` (node/way/relation) and `@id` (OSM ID) metadata fields. May include `distance_m` for proximity queries.

  - `type: Literal["Feature"]`

    Always `Feature`

    - `"Feature"`

  - `id: Optional[str]`

    Compound identifier in `type/osm_id` format

### Example

```python
import os
from plaza import Plaza

client = Plaza(
    api_key=os.environ.get("PLAZA_API_KEY"),  # This is the default and can be omitted
)
geo_json_feature = client.elements.lookup()
print(geo_json_feature.id)
```
