Issue:

We currently lack a way to notify consumers of our API about deprecated endpoints directly through the API responses. To improve communication about deprecated or soon-to-be removed functionality, it would be beneficial to add a deprecation_message field to our GET/POST/PUT decorators.

Expected Behavior:

When a client makes a request to a deprecated endpoint, the response should include a clear deprecation_message. This would give API consumers the necessary information about the status of the endpoint and any actions they need to take.
