 * **Extra query options**:
     * `:limit` - restrict the maximum amount of returned results, e.g. `limit: 5`
+    * `:autocomplete` - Use the automplete API, only when doing forward geocoding e.g. `autocomplete: true`
 * **Extra params** (see [Geoapify documentation](https://apidocs.geoapify.com/docs/geocoding) for more information)
     * `:type` - restricts the type of the results, see API documentation for
       available types, e.g. `params: { type: 'amenity' }`
