Get revision information.

May be used in several ways:
# Get data about a set of pages (last revision), by setting titles or pageids.
# Get revisions for one given page, by using titles or pageids with start, end, or limit.
# Get data about a set of revisions by setting their IDs with revids.

Get deleted revision information.

May be used in several ways:
# Get deleted revisions for a set of pages, by setting titles or pageids. Ordered by title and timestamp.
# Get data about a set of deleted revisions by setting their IDs with revids. Ordered by revision ID.

You can export the text and editing history of a particular page or set of pages wrapped in some XML.
This can be imported into another wiki using MediaWiki via the [[Special:Import|import page]].

To export pages, enter the titles in the text box below, one title per line, and select whether you want the current revision as well as all old revisions, with the page history lines, or the current revision with the info about the last edit.

In the latter case you can also use a link, for example [[{{#Special:Export}}/{{MediaWiki:Mainpage}}]] for the page "[[{{MediaWiki:Mainpage}}]]".

Get data with content for the last revision of titles <kbd>API</kbd> and <kbd>Main Page</kbd>.

Parses content and returns parser output.

See the various prop-modules of <kbd>[[Special:ApiHelp/query|action=query]]</kbd> to get information from the current version of a page.

There are several ways to specify the text to parse:
# Specify a page or revision, using <var>$1page</var>, <var>$1pageid</var>, or <var>$1oldid</var>.
# Specify content explicitly, using <var>$1text</var>, <var>$1title</var>, and <var>$1contentmodel</var>.
# Specify only a summary to parse. <var>$1prop</var> should be given an empty value.

Imageinfo returns information about file revisions (normally the last revision since <code>iilimit</code> defaults to 1). <code>userid</code> includes the ID of the user who made the (re)upload which created that revision. So there will be one user ID per imageinfo item; if you set the limit high enough, you will get all revisions of all files as separate imageinfo items.
