Objects: a new way to group people together

Objects: a new way to group people together
To create objects, you’ll define their type—like companies, accounts, and so on. Then you’ll create them—this process is a bit like identifying people. You’ll identify an object, set its attributesA key-value pair that you associate with a person—like their name, the date they were created in your workspace, etc. Use attributes to target people and personalize messages., and then add relationships to people.
Then you can create segments of people based on their relationships to objects.

This is awesome!
We’d like to use objects programmatically (using REST APIs).
I can see that we can already set/update object attributes via the Track API
https://customer.io/docs/journeys/objects/#create-object-api

However, I cannot find an endpoint in the App API to fetch current attributes on an object.
https://customer.io/docs/api/app/#operation/getPersonAttributes offers to fetch attributes for a customer.
In order to start using objects, we’d need a similar API that fetches attributes for an object.
Is there such an API (maybe in beta) which we could try?

Thanks!
