API:Information in Wikimedia projects

Wikimedia's free open knowledge is available on wiki sites that anyone can edit, all running MediaWiki software. You're probably familiar with Wikipedia in your own language, but the range of content is larger.

Wikipedia and beyond
The "Wikipedia" in a particular language, such as https://vi.wikipedia.org in Vietnamese hosts information on thousands to millions of subjects.

The unit of information on a wiki is a page, for example https://vi.wikipedia.org/wiki/Cừu nhà is the Vietnamese article on "Sheep". Just as users view encyclopedia pages, you can use MediaWiki APIs to access page content and get information about it.

Other wikis
The Wikimedia Foundation supports many other collections of information: See Our projects on the Wikimedia Foundation site for a complete list.
 * Wiktionary dictionary material in many languages
 * WikiSource archives a collection of free and open content texts
 * WikiBooks
 * WikiVoyage has user-curated travel information in several languages
 * Wikiquote is a repositoryof quotations

Access to project information
You use the same APIs to access all this content:


 * You can simply link to articles.
 * Display article HTML in your own application using a fast caching API called RESTBase.
 * Get information about articles using the MediaWiki "action=query" API, as explained in Page info in search results, and display these snippets of information.

To deal with languages, Wikimedia's sister project Wikidata maintains "sitelinks" between all these different ventures in different languages.
