Add rate limiting for pagination

**Problem**
When working with models, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

Start by reconciling the title's pagination rate-limiting request with the body’s broader request for model error messages; the payload names no files, entry points, or tests. Confirm which behavior is intended and identify the relevant implementation and test locations before defining completion criteria.
