This is a Python library designed to make it easy for developers to access and parse data from Wikipedia using the MediaWiki API. Specific methods available through this library include searching Wikipedia, getting article summaries, getting images, and more.
Less than two months ago, Merriam-Webster announced that some of its references would be available via an API. Now, competitor Cambridge University Press has followed suit with the Cambridge Dictionaries Online API. Currently, Cambridge offers five dictionaries through an API (i.e. Cambridge Advanced Learner's Dictionary, Cambridge Dictionary of American English, Cambridge Business English Dictionary, Cambridge Learner's English-Turkish Dictionary, and Cambridge Leaner's Dictionary).
U.S. National Library of Medicine, which is part of the National Institutes of Health, maintains a database of over 8,500 records relating to other organizations and sources of reference material on the topic of health and medicine. This “Directory of Information Resources Online” is aptly named DIRLINE. The DIRLINE API allows you to search this niche data collection from your webpage or app.
