The request is for Special:PrefixIndex to return a count of the number of pages it finds and is able to return that number through the API and the magic word...

The special page should show "Showing results 1-50 of 115" so people can see how many (sub-)pages there are with this prefix.

This would allow for something like: {{#ifexpr:{{Special:PrefixIndex/Wikipedia:Requests for adminship/User:Example|count=yes}}>1|[{{fullurl:Special:PrefixIndex|prefix=Requests+for+adminship%2FUser:Example&namespace=4}} RfAs]}} to only show the link if there are actually results.

So, this number should be available to access through the magic word and the API as well.
