API:Information in Wikimedia projects

Wikimedia's free open knowledge is available on web 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 a wiki page that is the Vietnamese article on "Sheep".

Other wikis
The Wikimedia Foundation supports many other collections of information, see Our projects on the Wikimedia Foundation site for a complete list: There are two wikis that hold language-independent information:
 * Wiktionary hosts dictionary material in many languages
 * WikiSource archives a collection of free and open content texts
 * WikiVoyage has user-curated travel information in several languages
 * for example, https://en.wikivoyage.org/wiki/Paris is the English Wikivoyage article about Paris
 * Wikiquote is a repository of quotations
 * Wikiquote is a repository of quotations
 * Commons hosts millions of freely usable
 * https://commons.wikimedia.org/wiki/File:Paris_Night.jpg

Accessing information
You can simply link to pages in these wikis. You can also access the information in the page. You use the same APIs to access all this content:


 * 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.
