REST Architectural Style is one of 4 APIs that [REST](https://apis.io/providers/rest/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Architecture, HTTP, REST, and Web Services. The published artifact set on APIs.io includes API documentation.

Representational State Transfer (REST) is an architectural style originally defined by Roy Fielding. REST provides six guiding constraints: client-server separation, statelessness, cacheability, uniform interface, layered system, and optional code-on-demand. Any API conforming to these constraints is considered RESTful.
