Retrieve linked wikidata entities having a wikipedia page

问题

I want to query wikidata by free text or by category, to return entities who has a corresponding wikipedia page.

For each page (or for a selected page) I want to fetch all the linked wikidata entities who have a corresponding wikipedia article.

Note that:

• for each wikipedia page and linked pages, I want to fetch the corresponding Wikidata Id
• a linked wikidata entity may exist on other wikipedias, not necessarily in the queried language

(e.g. a page in French History is available in multiple languages; I may have linked pages in French only as well as others multiple languages).

I cannot figure out which wikidata APIs to corresponding ones in wikipedia, to query linked articles, and how to query linked pages that exist even beyond a selected language.

I looked at:

https://www.mediawiki.org/wiki/Wikidata_Query_Service/User_Manual/MWAPI

https://www.mediawiki.org/wiki/API:Links

For example I may start with this sparql query:

SELECT ?item ?type ?itemLabel ?typeLabel WHERE {
 {
   SELECT ?item WHERE {
    SERVICE wikibase:mwapi {
      bd:serviceParam wikibase:endpoint "en.wikipedia.org" .
      bd:serviceParam wikibase:api "Generator" .
      bd:serviceParam mwapi:generator "search" .
      bd:serviceParam mwapi:gsrsearch "artificial intelligence" .
      bd:serviceParam mwapi:gsrlimit "max" .
      ?item wikibase:apiOutputItem mwapi:item .
    }
  } LIMIT 100
 }
 hint:Prior hint:runFirst "true".
 ?item wdt:P31|wdt:P279 ?type .
 SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
} LIMIT 100

Could you show examples to expand or adapt this query ?

Could you suggest other references than https://www.mediawiki.org/wiki/Wikidata_Query_Service/User_Manual/MWAPI , for an extensive use to callout to Mediawiki API from SPARQL (so that I can exploit wikidata and wikipedia) ?
