## Get feature by type and ID

`client.elements.lookup(RequestOptionsoptions?): GeoJsonFeature`

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

Get feature by type and ID

### Returns

- `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: Array<number> | Array<Array<number>> | Array<Array<Array<number>>> | Array<Array<Array<Array<number>>>>`

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

      - `Array<number>`

      - `Array<Array<number>>`

      - `Array<Array<Array<number>>>`

      - `Array<Array<Array<Array<number>>>>`

    - `type: "Point" | "LineString" | "Polygon" | 3 more`

      Geometry type

      - `"Point"`

      - `"LineString"`

      - `"Polygon"`

      - `"MultiPoint"`

      - `"MultiLineString"`

      - `"MultiPolygon"`

  - `properties: Record<string, unknown>`

    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: "Feature"`

    Always `Feature`

    - `"Feature"`

  - `id?: string`

    Compound identifier in `type/osm_id` format

### Example

```typescript
import Plaza from '@plazafyi/sdk';

const client = new Plaza({
  apiKey: process.env['PLAZA_API_KEY'], // This is the default and can be omitted
});

const geoJsonFeature = await client.elements.lookup();

console.log(geoJsonFeature.id);
```
