Refactor routes for better readability

**Description**
Currently validation lacks proper retry support.

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

**Priority**: Low/Medium

The issue names route readability and validation retry support but does not identify files, tests, or entry points. Start by locating the validation and route-handling code, then determine where retry configuration belongs; done means configurable retries with sensible defaults are implemented and validated by the relevant tests.
