Returns one row per company: the cost of every service for the requested period plus the resulting total.

Access is enforced per caller. With onlyForMyCompany=true the response holds a single row — the company of the authenticated user — and requires the corresponding read permission on that company. Without that flag the operation returns every company the platform bills and requires platform-wide access; a caller without it receives 403.

Rows are always ordered by priceTotal descending — the order cannot be changed, and sort, fields and page are not supported here. Use limit together with offset to paginate.
