at glance, sounds haven't enabled mirror api in code console project.

1. go https://code.google.com/apis/console/ , select project you're working on.
2. select services menu item on left.
3. scroll down google mirror api , make sure turned on.

if not have api available, means haven't been whitelisted it. if you're glass explorer, contact glass guide using 800 number or email address support , ask permitted. if not glass explorer, api isn't available @ time unless glass explorer permits access 1 of projects.
