You can check recentchanges for the page. Relevant changes to wikidata items used on a page are injected into the recentchanges stream, so they show up in the watchlist of people watching the page on wikipedia. You may need to set rctype=edit|external in your API query though.
Note that this does not (yet) work for the page history, just recentchanges.
You can also look at the "touched" timestamp as returned by the API: https://en.wikipedia.org/w/api.php?action=query&prop=info&titles=Main%20Page
This will be updated whenever the page is purged/rerendered, e.g. when a template changed - or a wikidata item.

With the advent of Wikidata-based infoboxes, the page contents can change without the local text being changed, so without a new revision. Is there any way tho find out when this happens from the API? I know I can always do 2 API calls, one for the page and one for the item, but that's time consuming.
Thanks, Strainu
