Hi,
The validation-status data can and sometimes is stored in Wikidata. See how
it is stored here :
https://www.wikidata.org/wiki/Help:Badges and here an
example of Wikidata query for all items about validated text :

Thad said, most of the times Wikidata is not up-to-date, and there should
be a tool to take care of that instead of human being.
