How can I keep track of how many projects are associated with an Schema?

[laralg]

Hello,

I want to have somewhere a report of the configuration of my projects. Like this schema has 20 projects associated, or this issuetype is in these schema. So I can catch before hand if something unusual happens (like a project getting deleted by mistake).

Can I call Jira configuration by REST? Would I need to get this info directly from the database?

Thanks
