Thread:Project:Support desk/iwlinks

Hello, I'm trying to use wikipedia's API to get lists of wikilinks from a given wiki to other ones (no matter the specific page, this is for a graphsearch project). On http://en.wikipedia.org/w/api.php, I found "prop=iwlinks" that seems to do that. So for a random webpage, I tried: http://en.wikipedia.org/w/api.php?action=query&prop=iwlinks&titles=San_Francisco&iwlimit=20 which doesn't work (what it returns is clearly not a list of 20 wikilinks) while a similar request: http://en.wikipedia.org/w/api.php?action=query&prop=images&titles=San_Francisco&imlimit=20 works well. How should I proceed? Thanks in advance!
