Well, by reading your API’s structure, we can automatically build beautiful and interactive API … As RESTful services grow in number, so do the programming languages that are wont to implement them, making it harder for them to speak .

OAS defines an API’s contract, allowing all the API’s stakeholders, be it your development team, or your end consumers, to know what the API does and interact with its various resources, without integrating it into their own application. But it's more than just a spec. Swagger is a framework which consists of multiple open source, free and few commercial tools for implementing OpenAPI specifications. During the development of Wordnik's products, the need for automation of API documentation and client SDK generation became a major source of frustration.

The Swagger UI framework allows both developers and non-developers to interact with the API in a sandbox UI that gives clear insight into how the API responds to parameters and options. The  API documentation is often thought of as the interface for consuming an API, and as such, must facilitate interaction between these different web services. It reads OpenAPI specification’s json file and renders the interactive page in the browser. The @ApiParam annotation is for use solely with the JAX-RS 1.x/2.x parameter annotations like @PathParam, @QueryParam, @HeaderParam, @FormParam, and @BeanParam.Although swagger-core scans these annotations by default, we can use @ApiParam to add more details about the parameters or change the values as they are read from the code.. Swagger editor is an online editor. Enables us to share the APIs privately and publicly. Swagger (now the “Open API Initiative”) is a specification and framework for describing REST APIs using a common language that everyone can understand. Swagger includes automated documentation, code generation (into many programming languages), and test-case generation. But because the landscape changes, and developers are expected to enhance the quality and readability of the APIs they deliver, the necessity for an easy API testing and documentation generation tool on the fly became apparent to us. The ability of an API to describe its own structure is the root of all the awesomeness. You can preview the changes at real-time. The concept for the user interface was proposed by Ayush Gupta, who suggested that an interactive user interface would benefit end users who wished to "try out" and develop against the API. Is the swagger.json file never actually written to disk? The other issue is facilitating interaction between multiple web services. Applications are made from multiple services that constantly communicate and interact with one another .
