No, it’s returning details about all active user api keys.
Try running the query below:
SELECT * FROM user_api_keys
I’m assuming it will only return 7 rows. Let me know if that’s not the case.
Not necessarily. When users access the site via the DiscourseHub app, their requests to the site count as User API requests. If a few of the users are actively reading the site, they could generate 2k requests in a day.
