Is it possible to query api for activity on private repos, without authentication?

Of course I wouldn’t expect to get any real information about activity on a private repo, but what I’m looking for is just the information you see on someone’s activity graph if they have “Include private contributions on my profile” enabled. Just enough information to note that this user performed some event on this day in a private repo.

I’m writing a portfolio page for myself which pulls down my activity on GitLab, GitHub, and Bitbucket using a scraper, and then presents all of my activity in one place. I’ve written a scraper that gets all of my commits for GitLab, and presents the data in an activity graph. But so far I haven’t found a way to be able to include my activity in private repos to this.

If there is some way to do this, any advice would be appreciated. If not, where would be the best place to request an API call for this?
