Hi,
For the list of all disambiguation pages, wouldn't it be better to use the existing pageswithprop request, rather than having a specific request ? Request with pageswithprop: https://en.wikipedia.org/w/api.php?pwplimit=max&action=query&pwppropname=disambiguation&list=pageswithprop And it's not even limited to a maximum number of pages since it implements query-continue mechanism.
