Handle edge cases in serialization

**Description**
Currently types lacks proper pagination support.

**Proposed solution**
Add configurable pagination with sensible defaults.

**Priority**: Low/Medium

No files, tests, or entry points are named. Start by locating the types and serialization code, then trace how paginated data is represented and consumed. Done means pagination is configurable, defaults are sensible, and the listed edge cases are handled without changing existing behavior unexpectedly.
