What is the Wikibase API?
Wikibase provides a general mechanism for storing statements as structured data. The statements about items live on the server at wikidata.org. See Wikidata:Glossary for more information on Wikibase and other concepts.



The Wikibase API allows querying, adding, removing and editing information on Wikidata or any other Wikibase instance.

It is provided via a set of extensions to MediaWiki API modules. So, to use the Wikibase API, you should have a basic familiarity with the MediaWiki Action API: actions, queries, etc., as well as with generic parameters such as  and.

How to use the Wikibase api
Send requests to the API through HTTP, the same as with the MediaWiki Action API. See API:Tutorial#How to use it for information about how to use the MediaWiki Action API.

Request Format
The endpoint for the API is https://wikidata.org/w/api.php.

In the query string, add the action parameter, which tells the API which action to perform. For example,  tells the API to get the data for Wikibase entities. For meta and property submodules, use  and   respectively.

Some parameters are nearly always available. Plural forms are used in those cases in which a parameter can take several values. The parameters are:

בקשת GET
הסבר על כל חלק בכתובת:


 * היא נקודת הגישה המרכזית.
 * אומר ל־API לקבל את הנתונים ליישויות ויקיבייס.
 * אומר לקבל נתונים מהוויקיפדיה האנגלית.
 * מציין את כותרת הדף ממנו לקבל נתונים.
 * מציין את המאפיינים המבוקשים מהיישויות, במקרה הזה המאפיין הוא התיאורים של היישויות.
 * אומר לסנן את התוצאות לאנגלית בלבד.
 * מציין פלט JSON שהיא תצורת הפלט המומלצת.

תשובה
The response of a request will usually contain:


 * A  key with a boolean cast as an integer if the request is successful. If the integer is zero, any additional values might be wrong.
 * An  key with an object of two, optionally three keys, ,   and  , if the request is unsuccessful.
 * Information about the action. The information is either passed on the top level or under item if it is one single item or items if it is several. If it is several items, each is found under a key with its own item id.

Empty objects are returned as JSON arrays and not as objects, while empty parameters remove the actual entry from the item.

Possible errors
Possible errors for any module can be found using. The error format corresponds to that of the MediaWiki Action API. See API:Errors and warnings#Legacy format.

All error messages from the Wikibase modules should be internationalized (i18n) and localized (l10n). The user language for the logged-in user will be the default for error messages, but you can override this by adding  to the URL query string.

Additional notes
Wikimedia Commons has its own Wikibase for properties of the files on Commons.
 * Many Wikimedia wikis run the Wikibase Client extension. This lets API clients on them to query the  meta submodule to determine URLs for the full Wikibase repo, and the   property submodule to get some Wikidata information about pages on the local wiki.
 * The calender models that can be used with Wikibase are the Gregorian calendar(Q1985727) and the Julian calendar(Q1985786).
 * The API uses revision ids for edit collision detection. If there is an edit collision, the requester must acquire a newer revision id to be able to continue. This typically involves requesting  for the item in question, and then storing (and using) the revision from the entry.
 * Any MediaWiki installation can run Wikibase. On the Wikimedia cluster, most wikis do not run the full set of Wikibase extensions.
 * Do not test the  value for a particular error, instead use the   value as this will remain independent of localization.
