How to get account creation date, profile color, followers count, and original username?

[simplifiedamber]

Hi,

I'm building a PSN profile lookup tool and hit a few walls. Looking for guidance on what's actually out there.

1. Account creation date

When I hit PS Direct for customerSince with another user's account ID, I get nothing. I've seen some bots/docs say it only works for your own account. Is there another endpoint that exposes creation date for arbitrary users?

2. Profile color

I've tried profile.api.playstation.com for profile color. With NPSSO auth I get 403 InsufficientScope. With a static Bearer token I get 401. So either I'm missing scopes or there's a different endpoint. Anyone know what actually works here?

3. Followers / following counts

The friendship summary endpoint (m.np.playstation.com/api/userProfile/v1/internal/users/me/friends/{account_id}/summary) gives me friendsCount and mutualFriendsCount, that's it. No follower or following counts in the response. Does PSN expose those somewhere else?

4. Original username (name change history)

Legacy profile2 (us-prof.np.community.playstation.net/userProfile/v1/users/{online_id}/profile2) has onlineId and currentOnlineId. When I search by the old username, it works and I get the current one. But when I search by the current username, I don't get the original or any previous usernames. So I can't build name history when I only have the current ID. Is there another way to get that?
