2.4. Interface for programing applications
MediaWiki has an expandable API (an interface for programming applications), which provides direct access on a high level to data contained in MediaWiki databases. Client programs can use the API to log in, gain data and send changes. The API interface supports certain JavaScript web clients and end-user applications (e.g. anti-vandalism tools). API interfaces can be accessed from the backend of another web server.
