## Execute a PlazaQL query

**post** `/api/v1/query`

Execute a PlazaQL query

### Query Parameters

- `format: optional string`

  Response format: json (default), geojson, csv, ndjson

### Body Parameters

- `data: string`

  PlazaQL query string

### Returns

- `FeatureCollection = object { features, type }`

  GeoJSON FeatureCollection (RFC 7946). For paginated endpoints, metadata is returned in HTTP response headers rather than the body:

| Header          | Description                                      |
| --------------- | ------------------------------------------------ |
| `X-Limit`       | Requested result limit                           |
| `X-Has-More`    | `true` if more results exist                     |
| `X-Next-Cursor` | Opaque cursor for next page (cursor pagination)  |
| `X-Next-Offset` | Numeric offset for next page (offset pagination) |
| `Link`          | RFC 8288 `rel="next"` link to the next page      |

  Content-Type is `application/geo+json`.

  - `features: array of GeoJsonFeature`

    Array of GeoJSON Feature objects

    - `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 of number or array of array of number or array of array of array of number or array of array of array of array of number`

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

        - `Point = array of number`

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

        - `LineStringOrMultiPoint = array of array of number`

          Array of [lng, lat] positions

        - `PolygonOrMultiLineString = array of array of array of number`

          Array of linear rings / line strings

        - `MultiPolygon = array of array of array of array of number`

          Array of polygons

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

        Geometry type

        - `"Point"`

        - `"LineString"`

        - `"Polygon"`

        - `"MultiPoint"`

        - `"MultiLineString"`

        - `"MultiPolygon"`

    - `properties: map[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: optional string`

      Compound identifier in `type/osm_id` format

  - `type: "FeatureCollection"`

    Always `FeatureCollection`

    - `"FeatureCollection"`

### Example

```http
curl https://plaza.fyi/api/v1/query \
    -H 'Content-Type: application/json' \
    -H "Authorization: Bearer $PLAZA_API_KEY" \
    -d '{
          "data": "$$ = search(node, amenity: \\"cafe\\").around(distance: 500, geometry: point(48.8566, 2.3522));"
        }'
```
