Add rate limiting for sorting

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

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

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

The issue does not name any files, tests, or entry points, and its title conflicts with the body. First inspect the authentication and sorting entry points, then confirm which behavior is intended with the maintainers. Done should mean the agreed rate-limiting or error-message behavior is implemented and covered by relevant tests.
