DeltaQuad suggested I tell the bots developers on this list about this
tool, because he hadn't heard about it.
Max Semenik wrote a GUI tool to help newbies explore the MediaWiki API.
It's called the API Query Sandbox. You can try it here:

Please file bugs and enhancement requests in
bugzilla.wikimedia.org
(Product: MediaWiki extensions, Component: ApiSandbox). We want to make
this better.
Thanks!
