I've been trying to make a mash-up of my Zotero library's feed using Yahoo Pipes, but Pipes isn't accepting the feed url as valid (even though it works in my other RSS readers). Is this because the Zotero API is https and not http? Is there any way to get an http feed?

and you can DIY if you don't want to wait:
