What is Api route middleware in Laravel, and what role does it play in a real application? In Laravel, API route middleware should be understood as part of a larger application architecture rather than as an isolated API call. API routes can share middleware such as authentication, throttling and request normalization. A strong understanding includes its purpose, the layer where it belongs, the data or request flow it affects, and the situations where another mechanism may be more appropriate. Practical context: Laravel can expose HTTP APIs through routes that map HTTP verbs and resource URLs to controller actions or other handlers. The specific focus here is API route middleware: API routes can share middleware such as authentication, throttling and request normalization. This question is designed to test not only terminology, but also how the concept fits into Laravel's request, application, database, security, or deployment workflow.
