API for user activity

Hi all,

The use case:
We want to see reports of weekly activity per user.
We use tools that gathers information from different sources such as Bugzilla, Git, etc. but there is no API for this specific query.

I have created workaround which sends request to: sentry.io/api/0/organizations/org_name/activity/
But it returns all activity for all users from day 1.
