regardless of what arguments I try to pass, they seem to get ignored, and I just get the same response, so I must have the formatting wrong. I can't see a clear example in the library documentation re. how to pass arguments / clarify the desired endpoint

e.g.
r = wpapi.get("posts")

(and then printing the json contents of the variable 'r')

... yields the same response as:

r = wpapi.get("posts?status=draft")

or

r = wpapi.get("posts?slug=member_post_abc")

If you could please clarify, I'd be grateful.
