# Fetch sortable fields for /search

`GET /sortables`

## Request

- Base URL: `https://data.geo.admin.ch/api/stac/v1`
- URL: `https://data.geo.admin.ch/api/stac/v1/sortables`
- Auth: none declared

This endpoint returns a list of properties (or aliases) that can be used in the `sortby` parameter for the cross-collection item search (i.e. `GET /search` and `POST /search`). It returns a JSON Schema that defines the properties allowed in `sortby`. The precise definition of this can be found in the [OGC API - Features - Part 5: Schemas](https://docs.ogc.org/is/23-058r2/23-058r2.html).

## Response `200`

A JSON Schema defining the properties allowed in `sortby`.

If `additionalProperties` is set to `false`, property references that are not explicitly declared in the sortables schema SHALL result in a 400 response.
