Add rate limiting for pagination

**Description**
Currently config lacks proper caching support.

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

**Priority**: Low/Medium

Start by reconciling the title's request for pagination rate limiting with the description's request for configurable caching. Locate the pagination, configuration, and caching entry points, then confirm the intended behavior and sensible defaults with the maintainers. Done means the scope is agreed and the relevant behavior is covered by tests, but no test or file is named in the issue.
