How about this?
 * http://fallout.wikia.com/api.php?action=query&list=wkpoppages&wklimit=500

The order is slightly different, but appears to be legit because the pages I would expect to be near the top are still near the top.

And since you did ask about specific pages:
 * http://fallout.wikia.com/api.php?action=query&list=wkpoppages&wkpage=14174

edit: It would appear that this is the most popular of all time, and only counts total page views, while Special:Top is obviously "recently popular"

edit: Some pages created months ago do not appear in that list, even when using wkpage - so it looks like this isn't going to help much.

Here's the limit for Fallout

edit: It's more out of date that I first assumed: The strange thing is that the "last edit date" is current for all articles, it simply doesn't list articles created after a certain date.
 * Articles created before 2012‎-09-01 are listed
 * Articles created after 2012‎-09-28 are not listed.

Edit: Those dates weren't for the fallout wiki specifically, I tried to download the fallout database dump to verify, but it is truncated and does not contain all articles.
