POSIX
POSIX (Portable Operating System Interface) is a family of IEEE and Open Group standards that define a consistent operating system API, command line shell, and utility interfaces for maintaining compatibility between Unix and Unix-like systems. It is a specification rather than a network API, and there is no public REST or HTTP interface for the standard.
