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.

https://www.mediawiki.org/wiki/Special:MyLanguage/API:Deletedrevisions

Specific parameters:

Other general parameters are available.

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. For performance reasons, if this option is used, drvlimit is enforced to 50.
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). For performance reasons, if this option is used, drvlimit is enforced to 50.

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 *.

drvcontentformat-{slot}

Content serialization format used for output of content.

This is a templated parameter. When making the request, {slot} in the parameter's name should be replaced with values of drvslots.

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

drvlimit

Limit how many revisions will be returned. If drvprop=content, drvprop=parsetree, drvdiffto or drvdifftotext is used, the limit is 50. If drvparse is used, the limit is 1.

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 the section with this identifier.

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. For performance reasons, if this option is used, drvlimit is enforced to 50.

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. For performance reasons, if this option is used, drvlimit is enforced to 50.

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

Only list revisions by this user.

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

drvexcludeuser

Don't list revisions by this user.

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

drvcontinue

When more results are available, use this to continue. More detailed information on how to continue queries can be found on mediawiki.org.

Examples:

List the information for deleted revision 123456.: api.php?action=query&prop=deletedrevisions&revids=123456 [open in sandbox]
