# List Cost Allocation

`GET /coa/api/cost-allocations`

Retrieve a list of cost allocations with optional filtering and sorting.

        Supports including soft-deleted records for audit and recovery purposes.
        When include_deleted=true, returns ONLY deleted records instead of active records.
        Deleted records contain minimal data: 'id', 'is_deleted=true', 'deleted_at' timestamp,
        and 'last_modified_at'. When 'false' or omitted, returns ONLY active records.
        This provides clean separation between active and deleted data.

## Query parameters

- `include_deleted` boolean
