Can we pull all open tickets through the API based on technician's API key permission settings?

We would like to pull all open requests for individual support groups. I do not see a filter provided for it here unless i have over looked it. I thought maybe there may be a work around where the API key associated in the URL, might only pull requests that the technician themselves are associated with. Is this possible?

Get all open requests (Open_System) returns a json object that does not differentiate by support groups, so i cannot iterate through the objects to separate them out by groups. 

INPUT_DATA={     "operation": {         "details": {             "from": "0",             "limit": "500",             "filterby": "Open_System"         }     } }
