Thanks guys, glad I'm not missing something and the feature would be useful for others as well.
Ideally we'd want it as an Org wide call - ideally ideally it would be part of the same /organizations/:organizationId/appliance/uplinks/usage/byNetwork call which is currently in Beta. If that same org wide call could be made generic and return uplink usage for all device types that would be amazing! @John_on_API please!
