I'd like to work on this issue.

I'll integrate OpenAPI/Swagger to provide auto-generated API documentation with an interactive Swagger UI. I'll document all endpoints, request and response schemas, authentication flows, common error responses, and example payloads, while adding documentation versioning where appropriate. I'll also include tests to verify the generated specification remains accurate and ensure the implementation integrates cleanly with the existing API.
