built 661 days ago
An Application Programming Interface is the set of calling conventions by which an application program accesses operating system and other services. An API is defined at source code level and provides a level of abstraction between the application and the kernel (or other privileged utilities) to ensure the portability of the code.

Application Programming Interface: Integrating real-time tracking and messaging information into enterprise and third-party applications is quick and easy with Air-Trak's XML-based application programming interface (API). The API and library of web-services - which you may utilize at no additional charge - accelerate the development of custom system interfaces and web-based tracking applications using the same set of tools that Air-Trak used to create the Air-Trak Web Display.

OpenOffice.org offers a language independent application programming interface (API) which allows to program the office in different programming languages (e.g. C++, Java, Python, CLI, StarBasic, JavaScript, OLE). It allows to use OpenOffice.org as service provider in other applications, extend it with new functionality or simply customize and control OpenOffice.org.

To accomplish this, the asking program uses a set of standardized requests, called application programming interfaces (API), that have been defined for the program being called upon. Almost every application depends on the APIs of the underlying operating system to perform such basic functions as accessing the file system. In essence, a program's API defines the proper way for a developer to request services from that program.

An API can ... provide an interface between a high level language and lower level utilities and services which were written without consideration for the calling conventions supported by compiled languages. In this case, the API's main task may be the translation of parameter lists from one format to another and the interpretation of call-by-value and call-by-reference arguments in one or both directions.
