I agree with Fionn, but I’ll go one step further and say that to me the Page is not a resource, it’s a property of the request. That makes me chose option 1 query string only. It just feels right. I really like how the Twitter API is structured restfully. Not too simple, not too complicated, well documented. For better or worse it’s my “go to” design when I am on the fence on doing something one way versus another.
