Swagger Demo - GET, POST, PUT and Delete

Swagger is a set of open-source tools and specifications for building and documenting RESTful APIs. It was originally developed by Reverb Technologies and later acquired by SmartBear Software. The Swagger tools include the Swagger Editor, which allows you to write and edit Swagger specifications in YAML format, the Swagger UI, which generates an interactive API documentation website based on your Swagger specification, and the Swagger Codegen, which generates client libraries, server stubs, and other code based on your Swagger specification.
The Swagger specification defines a standardized format for describing RESTful APIs, including information about the available endpoints, request and response formats, authentication and authorization methods, and other details. This specification can be used to generate documentation, client libraries, and other tools for interacting with the API. It is also designed to be human-readable and easy to understand, even for non-technical stakeholders.
