 The OpenAPI Specification is a community-driven open specification within the [OpenAPI Initiative](https://www.openapis.org/), a Linux Foundation Collaborative Project.
 
 The OpenAPI Specification (OAS) defines a standard, programming language-agnostic interface description for [REST APIs](https://en.wikipedia.org/wiki/Representational_state_transfer), which allows both humans and computers to discover and understand the capabilities of a service without requiring access to source code, additional documentation, or inspection of network traffic. When properly defined via OpenAPI, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interface descriptions have done for lower-level programming, the OpenAPI Specification removes guesswork in calling a service.
