Can you explain the concept of maturity levels in REST architecture?

Answer from AI
The levels of REST architecture maturity (REST Maturity Model) describe how fully and correctly REST principles are implemented in an API. Usually, three levels are distinguished:
-
Level 0 (Swamp of POX) — the API uses a single HTTP endpoint and typically only POST requests with data in the body. There is no use of standard HTTP methods and URIs for resources.
-
Level 1 (Resources) — the API begins to use different URIs for different resources, but may still use a limited set of HTTP methods, for example, only POST.
-
Level 2 (HTTP Verbs) — standard HTTP methods (GET, POST, PUT, DELETE) are used for resource operations, which improves semantics and interaction.
-
Level 3 (Hypermedia Controls, HATEOAS) — the API provides hypermedia links in responses, allowing the client to dynamically navigate the API without hardcoded URIs.
The higher the maturity level, the more RESTful the API is considered, which improves scalability, usability, and standardization of interaction.
