- `sort_by` string
- `environment` 'prod' | 'test'

## Request body

- object
  - `filters` Filters: Each key is a field to filter on, and each value is a condition: `{"<field>": {"operator": "<operator>", "value": [...]}}`. A result must match every condition. To set two conditions on one field, such as a range, pass a list of conditions. **Operators:** `""` (equals, the default), `not`, `in`, `not_in`, `lt`, `lte`, `gt`, `gte`, `contains`, `not_contains`, `icontains` (ignores case), `startswith`, `not_startswith`, `endswith`, `not_endswith`, `empty`, `not_empty`. Put values in a list: `""` and `in` match any of the listed values, and `not` and `not_in` match none of them. Other operators take one value; for `empty` and `not_empty`, send `[""]`. The fields you can filter on depend on the endpoint; `metadata__<key>` filters custom metadata where the endpoint supports it.
