Who and what the documents are about: people, pets, vehicles, homes, accounts, policies, companies. Renamed, combined and answered here as on the page.
By kind, each with how much paper it is on and the one status Home shows. VINs, plates and the like are details that come back only with the identifiers scope.
The name, the kind, what is known about it (attributes, merged; a null value removes one), when it was sold or ended (disposed_at), whether it is pinned, and whether it is part of the household (household, which is what the setup cards ask). At least one field. Something disposed of has its open items closed.

Headers
Idempotency-Keystringheader
Any string of the caller's choosing. The same key with the same body within a day replays the first answer, marked Idempotent-Replayed: true; with a different body it is 422; while the first call is still running it is 409.
The token, the role or the plan does not allow it. A missing scope is named in scope and in the WWW-Authenticate header as insufficient_scope; a plan that does not come with it says which one does.
