For what it’s worth, we’d also greatly appreciate this capability. We’ve wanted to give direct access to admin reports to non-moderators for grant-writing and/or marketing purposes. By and large, they just want stats like signups, posts, likes, page_view_total_reqs and topics from /admin/reports/X.
The ability to hand off an API key with just this report access (and no other admin capabilities) would be awesome. We’d probably want the handful of reports that expose private info turned off (like user_notes, user_flagging_ratio, and staff_logins), but all other admin reports are entirely summary stats and don’t require admin-level (or even moderator-level) trust to view IMO.
