Get deleted revision information.

May be used in several ways:

  1. Get deleted revisions for a set of pages, by setting titles or pageids. Ordered by title and timestamp.
  2. Get data about a set of deleted revisions by setting their IDs with revids. Ordered by revision ID.
Parameters:
drvprop

Which properties to get for each revision:

ids
The ID of the revision.
flags
Revision flags (minor).
timestamp
The timestamp of the revision.
user
User that made the revision. If the user has been revision deleted, a userhidden property will be returned.
userid
User ID of the revision creator. If the user has been revision deleted, a userhidden property will be returned.
size
Length (bytes) of the revision.
slotsize
Length (bytes) of each revision slot.
sha1
SHA-1 (base 16) of the revision. If the content has been revision deleted, a sha1hidden property will be returned.
slotsha1
SHA-1 (base 16) of each revision slot. If the content has been revision deleted, a sha1hidden property will be returned.
contentmodel
Content model ID of each revision slot.
comment
Comment by the user for the revision. If the comment has been revision deleted, a commenthidden property will be returned.
parsedcomment
Parsed comment by the user for the revision. If the comment has been revision deleted, a commenthidden property will be returned.
content
Content of each revision slot. If the content has been revision deleted, a texthidden property will be returned.
tags
Tags for the revision.
roles
List content slot roles that exist in the revision.
parsetree
Deprecated. Use action=expandtemplates or action=parse instead. The XML parse tree of revision content (requires content model wikitext).
Values (separate with | or alternative): comment, content, contentmodel, flags, ids, parsedcomment, roles, sha1, size, slotsha1, slotsize, tags, timestamp, user, userid, parsetree
Default: ids|timestamp|flags|comment|user
drvslots

Which revision slots to return data for, when slot-related properties are included in drvprops. If omitted, data from the main slot will be returned in a backwards-compatible format.

Values (separate with | or alternative): main
To specify all values, use *.
drvlimit

Limit how many revisions will be returned.

Type: integer or max
The value must be between 1 and 500.
drvexpandtemplates
Deprecated.

Use action=expandtemplates instead. Expand templates in revision content (requires drvprop=content).

Type: boolean (details)
drvgeneratexml
Deprecated.

Use action=expandtemplates or action=parse instead. Generate XML parse tree for revision content (requires drvprop=content).

Type: boolean (details)
drvparse
Deprecated.

Use action=parse instead. Parse revision content (requires drvprop=content). For performance reasons, if this option is used, drvlimit is enforced to 1.

Type: boolean (details)
drvsection

Only retrieve the content of this section number.

drvdiffto
Deprecated.

Use action=compare instead. Revision ID to diff each revision to. Use prev, next and cur for the previous, next and current revision respectively.

drvdifftotext
Deprecated.

Use action=compare instead. Text to diff each revision to. Only diffs a limited number of revisions. Overrides drvdiffto. If drvsection is set, only that section will be diffed against this text.

drvdifftotextpst
Deprecated.

Use action=compare instead. Perform a pre-save transform on the text before diffing it. Only valid when used with drvdifftotext.

Type: boolean (details)
drvcontentformat
Deprecated.

Serialization format used for drvdifftotext and expected for output of content.

One of the following values: application/json, application/octet-stream, application/unknown, application/x-binary, text/css, text/javascript, text/plain, text/unknown, text/x-wiki, unknown/unknown
drvstart

The timestamp to start enumerating from. Ignored when processing a list of revision IDs.

Type: timestamp (allowed formats)
drvend

The timestamp to stop enumerating at. Ignored when processing a list of revision IDs.

Type: timestamp (allowed formats)
drvdir

In which direction to enumerate:

newer
List oldest first. Note: drvstart has to be before drvend.
older
List newest first (default). Note: drvstart has to be later than drvend.
One of the following values: newer, older
Default: older
drvtag

Only list revisions tagged with this tag.

drvuser

Type: user, by any of user name, IP, interwiki name (e.g. "prefix>ExampleName") and user ID (e.g. "#12345")
drvcontinue

When more results are available, use this to continue.

Examples:
List the deleted revisions of the pages Main Page and Talk:Main Page, with content.
api.php?action=query&prop=deletedrevisions&titles=Main%20Page|Talk:Main%20Page&drvslots=*&drvprop=user|comment|content [open in sandbox]
