403 Forbidden Calling Enterprise Events - Mayeb It's Account Type?

I'm trying to call the Enterprise Events from the API. Other calls seem to work, but for this one I get a 403 Forbidden (see below). I suspect either I'm getting the stream_position all wrong (I've tried a multitude of values here) or maybe my development account doesn't have "enterprise" features. I don't know how to validate the latter. Of course, maybe I'm way off and have no idea what's wrong. Looking for pointers on how to diagnose. Thanks for any help.
