Fetch cached events with Node.js

My plan is to implement an anti-cheat into my game that's not constantly running, but players would report sketchy behaviour to my server alongside with the room id, region etc.
The server should then fetch all the events from the photon cache and process them. I obviouly can't trust any client with that task.

-- Is there any way to fetch the global/player cache from a third party?
-> I am using PUN

Thank you deeply for any help pointing me into the right direction
