Add rate limiting for monitoring

**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.

The issue names no files, tests, or entry points. First reconcile the title's monitoring rate-limiting request with the body’s model error-message request, then locate the relevant monitoring and model error-handling paths. Done should be defined as one of those changes being implemented with coverage for its expected behavior.
