The action=query module allows you to fetch information about a wiki and the data stored in it, such as the wikitext of a particular page, the links and categories of a set of pages, or the token you need to change wiki content .

API documentation


action=query

(main | query)

Fetch data from and about MediaWiki.

All data modifications will first have to use query to acquire a token to prevent abuse from malicious sites.

Parameters:
prop

Which properties to get for the queried pages.

Returns information about the given categories.
cirrusbuilddoc
Dump of a CirrusSearch article document from the database servers

Query modules

The query module has three types of submodules (also called query modules):

  • Properties of pages, including page revisions and content.
  • Lists of pages that match certain criteria.

Examples

Example 1: Specifying pages

Unlike meta and list query modules, all property query modules work on a set of pages that can be specified in one of the following ways:

  • By name using the titles parameter, e.g. titles=Foo|Bar|Main_Page.
  • By page ID using the pageids parameter, e.g. pageids=123|456|75915.
  • By revision ID using the revids parameter, e.g. revids=478198|54872|54894545. Most query modules will convert revision ID to the corresponding page ID. Only prop=revisions actually uses the revision ID itself.

GET request

Response

{
    "batchcomplete": true,
    "query": {
        "pages": [
            {
                "pageid": 1130,
                "ns": 0,
                "title": "Avicenna"
            },
            {
                "pageid": 17412,
                "ns": 0,
                "title": "Klein bottle"
            },
            {
                "pageid": 33642,
                "ns": 0,
                "title": "Warrant"
            }
        ]
    }
}

Example 2: Title normalization

Title normalization converts page titles to their canonical form.

This means capitalizing the first character, replacing underscores with spaces, and changing namespace to the localized form defined for that wiki.

Any trailing line breaks in page titles (\n) will cause odd behavior and they should be stripped out first.

GET request

Response

Example 3: Missing and invalid titles

Titles that don't exist or are invalid will have a missing or invalid attribute set in the response.

In output formats that support numeric array keys, missing and invalid titles will have negative page IDs.

GET request

Response

Example 4: Continuing queries

When all the data is not returned in the response of a query, there will be a continue attribute to indicate that there is more data.

To get further data, add its values to the original request.

GET request

Response

Example 5: Batchcomplete

The API returns a batchcomplete element to indicate that all data for the current batch of items has been returned. MW 1.25+

In the response of the sample query below, batchcomplete has been included to indicate that all the data for each of the three images has been returned.

The next continuation will begin returning data for the next set of 3 images.

GET request

Response

Example 6: Generators

Use generators if you want to get data about a set of pages.

For example, to get data about pages in a certain category, instead of querying list=categorymembers and then querying again with pageids set to all the returned pages, combine the two API calls into one by using generator=categorymembers.

When using a list module as a generator, you don't need to specify the pages.

However, for a property module, you should specify the pages which the generator will work on.

For example, to load all pages that are linked to from the main page, use generator=links&titles=Main%20Page.

Parameters passed to a generator must be prefixed with a g. For instance, when using generator=backlinks, use gbllimit instead of bllimit.

The sample query below gets links and categories for the first three pages in the main namespace starting with "Ba".

GET request

Response

Possible warnings

Warning message Cause
No support for special pages has been implemented. Thrown if a title in the Special: or Media: namespace is given. The pages in these namespaces cannot be queried.
Redirect resolution cannot be used together with the revids parameter. Any redirects the revids point to have not been resolved. Thrown if the redirect parameter is used in a query that specifies pages using revids.

Parameter history

  • v1.26: Introduced continue
  • v1.9: Introduced rawcontinue

Additional notes

  • Specifying titles through titles or pageids is limited to 50 titles per query, or 500 for those with the apihighlimits right.
  • Use multiple query modules together to get what you need in one request, e.g. prop=info|revisions&list=backlinks|embeddedin|allimages&meta=userinfo.
  • Generators only pass page titles to the query module and do not output any information themselves. Setting parameters like gcmprop will therefore have no effect.
