--- Comment #2 from Merlijn van Deen valhallasw@arctus.nl --- The actual query used is https://en.wikipedia.org/w/api.php?maxlag=5&format=json&rvprop=ids%7...
i.e. maxlag: 5 format: json rvprop: ids|flags|timestamp|user|comment|content prop: revisions|info|categoryinfo|templates|langlinks titles: Main Page meta: userinfo indexpageids: action: query uiprop: blockinfo|hasmsg
it's clear not all results are returned (see the continue header), BUT according to Yuri, the continue header uses here is broken (this is https://www.mediawiki.org/wiki/API:Legacy_Query_Continue instead of https://www.mediawiki.org/wiki/API:Query#Continuing_queries).
