Application programming interface (API) is a set of routines, protocols, and tools for building software and applications.

OSS, Inc can provide for you an API for a web-based system, operating system, or database system, and provides facilities to develop applications for that system using a given programming language. With the right API is easier to develop a program by providing all the building blocks. A programmer then puts the blocks together.
