The goal of Swagger™ is to define a standard, language-agnostic interface to REST APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection. When properly defined via Swagger, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interfaces have done for lower-level programming, Swagger removes the guesswork in calling the service.

Use cases for machine-readable API interfaces include interactive documentation, code generation for documentation, client, and server, as well as automated test cases. Swagger-enabled APIs expose JSON files that correctly adhere to the Swagger Specification, documented in this repository. These files can either be produced and served statically, or be generated dynamically from your application.

Without going into a long history of interfaces to Web Services, this is not the first attempt to do so. We can learn from CORBA, WSDL and WADL. These specifications had good intentions but were limited by proprietary vendor-specific implementations, being bound to a specific programming language, and goals which were too open-ended. In the end, they failed to gain traction.

Swagger does not require you to rewrite your existing API. It does not require binding any software to a service--the service being described may not even be yours. It does, however, require the capabilities of the service be described in the structure of the Swagger Specification. Not all services can be described by Swagger--this specification is not intended to cover every possible use-case of a REST-ful API. Swagger does not define a specific development process such as design-first or code-first. It does facilitate either technique by establishing clear interactions with a REST API.

This GitHub project is the starting point for Swagger. Here you will find the information you need about the Swagger Specification, a simple static sample of what it looks like, and some general information regarding the project.

The current version of the Swagger specification is 2.0 - and you can find it here.

This repository contains the existing Swagger 1.2 specification as well as proposals for the 2.0 version.

Each section should contain v1.2 and v2.0 folders to avoid confusion between the versions.

Please keep in mind that the other projects under Swagger use an independent version system. As such, don't confuse the version of the Swagger Specification they support and the version of that given library. For example, Swagger-Core with the version 1.3.2 supports Swagger Specification 1.2.

This includes:

• Static sample tutorial.
• List of known deployments.
• Revision history.
