<https://en.wikipedia.org/w/api.php?action=query&titles=Douglas%20Adams&prop=pageprops&formatversion=2>
maps a page title on the English Wikipedia to its Wikidata Q id.
You can also look this up directly on wikidata:
<https://www.wikidata.org/w/api.php?action=wbgetentities&sites=enwiki&titles=Douglas_Adams&props=>
<https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q42&props=sitelinks>
will do the reverse.
A bit more terse, and with full URLs in the output:
<https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q42&props=sitelinks|sitelinks/urls&sitefilter=enwiki>
You can also let yourself be redirected directly:
<https://www.wikidata.org/wiki/Special:GoToLinkedPage/enwiki/Q42>
Or the the reverse redirect:
<https://www.wikidata.org/wiki/Special:ItemByTitle/enwiki/Douglas_Adams>
