Api version is customizable, but looks like api limits to at most 10 km https://en.wikipedia.org/w/api.php?action=help&modules=query...
(Probably possible to do a sparql query for this at https://query.wikidata.org but seems like it would be complicated, at least given my relatively novice level of sparql skills)
Would be nice to be able to expand it so that I could discover interesting things a little further out but still in easy driving distance.
