What is the REST API endpoint for diag firewall iprope lookup?

I'm getting this, does that mean there are no policies that match the traffic?

{     'http_method': 'GET',     'results': {'success': False},     'vdom': 'root',     'path': 'firewall',     'name': 'policy-lookup',     'action': '',     'status': 'success',     'serial': 'FG201XXXXXXXX',     'version': 'v7.0.14',     'build': 601 }
