WikiAPI gives developers the ability to extract information on the fly directly from Wikipedia. Just to give a glimpse of what that means, imagine you want to display Wikipedia picture of the day on your website. Wikipedia does not provide such an API so what to do ? WikiAPI solves this problem by providing an endpoint specifically designed to achieve that goal. For example to get the Arabic picture of day on Wikipedia simply hit the endpoint
/wiki/home/pod?lan=ar
See available endpoints for a list of supported languages and types of information extraction the API can handle.
