MediaWiki API help
This is an auto-generated MediaWiki API documentation page.
Documentation and examples: https://www.mediawiki.org/wiki/Special:MyLanguage/API:Main_page
Main module
- Source: MediaWiki
- License: GPL-2.0-or-later
Status: The MediaWiki API is a mature and stable interface that is actively supported and improved. While we try to avoid it, we may occasionally need to make breaking changes; subscribe to the mediawiki-api-announce mailing list for notice of updates.
Erroneous requests: When erroneous requests are sent to the API, an HTTP header will be sent with the key "MediaWiki-API-Error" and then both the value of the header and the error code sent back will be set to the same value. For more information see API: Errors and warnings.
Testing: For ease of testing API requests, see Special:ApiSandbox.

- maxlag
Maximum lag can be used when MediaWiki is installed on a database replicated cluster. To save actions causing any more site replication lag, this parameter can make the client wait until the replication lag is less than the specified value. In case of excessive lag, error code maxlag is returned with a message like Waiting for $host: $lag seconds lagged.
See Manual: Maxlag parameter for more information.- Type: integer
- smaxage
Set the
s-maxage
HTTP cache control header to this many seconds. Errors are never cached.- Type: integer
- Default: 0
- maxage
Set the
max-age
HTTP cache control header to this many seconds. Errors are never cached.- Type: integer
- Default: 0
- assert

- One of the following values: anon, bot, user
- assertuser
Verify the current user is the named user.
- Type: user, by username

Any value given here will be included in the response. May be used to distinguish requests.

- Type: boolean (details)
- curtimestamp
Include the current timestamp in the result.
- Type: boolean (details)
- responselanginfo
Include the languages used for uselang and errorlang in the result.
- Type: boolean (details)
- origin
When accessing the API using a cross-domain AJAX request (CORS), set this to the originating domain. This must be included in any pre-flight request, and therefore must be part of the request URI (not the POST body).
For authenticated requests, this must match one of the origins in the
Origin
header exactly, so it has to be set to something like https://en.wikipedia.org or https://meta.wikimedia.org. If this parameter does not match theOrigin
header, a 403 response will be returned. If this parameter matches theOrigin
header and the origin is allowed, theAccess-Control-Allow-Origin
andAccess-Control-Allow-Credentials
headers will be set.For non-authenticated requests, specify the value *. This will cause the
Access-Control-Allow-Origin
header to be set, butAccess-Control-Allow-Credentials
will befalse
and all user-specific data will be restricted.- uselang
Language to use for message translations. action=query&meta=siteinfo with siprop=languages returns a list of language codes, or specify user to use the current user's language preference, or specify content to use this wiki's content language.
- Default: user

Variant of the language. Only works if the base language supports variant conversion.

- One of the following values: bc, html, none, plaintext, raw, wikitext
- Default: bc
- errorlang
Language to use for warnings and errors. action=query&meta=siteinfo with siprop=languages returns a list of language codes, or specify content to use this wiki's content language, or specify uselang to use the same value as the uselang parameter.
- Default: uselang
- errorsuselocal
If given, error texts will use locally-customized messages from the MediaWiki namespace.
- Type: boolean (details)

Data types
Input to MediaWiki should be NFC-normalized UTF-8. MediaWiki may attempt to convert other input, but this may cause some operations (such as edits with MD5 checks) to fail.
Parameters that take multiple values are normally submitted with the values separated using the pipe character, e.g. param=value1|value2 or param=value1%7Cvalue2. If a value must contain the pipe character, use U+001F (Unit Separator) as the separator and prefix the value with U+001F, e.g. param=%1Fvalue1%1Fvalue2.
Some parameter types in API requests need further explanation:
- boolean
Boolean parameters work like HTML checkboxes: if the parameter is specified, regardless of value, it is considered true. For a false value, omit the parameter entirely.
- expiry
Expiry values may be relative (e.g. 5 months or 2 weeks) or absolute (e.g. 2014-09-18T12:34:56Z). For no expiry, use infinite, indefinite, infinity or never.
- timestamp
Timestamps may be specified in several formats, see the Timestamp library input formats documented on mediawiki.org for details. ISO 8601 date and time is recommended: 2001-01-15T14:56:00Z. Additionally, the string now may be used to specify the current timestamp.
Templated parameters
Templated parameters support cases where an API module needs a value for each value of some other parameter. For example, if there were an API module to request fruit, it might have a parameter fruits to specify which fruits are being requested and a templated parameter {fruit}-quantity to specify how many of each fruit to request. An API client that wants 1 apple, 5 bananas, and 20 strawberries could then make a request like fruits=apples|bananas|strawberries&apples-quantity=1&bananas-quantity=5&strawberries-quantity=20.
