XF 2.2 Return only users from a specific usergroup via API

[SeToY]

Hey there,

I'm currently trying to fetch users that are within a specific usergroup. For that, I'm currently using the API endpoint /users/, but that route will not allow me to narrow down my search and I'd like to refrain from sending hundreds of requests just to filter out the users.

Is there a way to only request a subset of users via the API?

Thanks!
