It is possible to set Service Level Agreements / SLA Metrics details for a given Service Desk Management project. In Jira Service Management project, those are listed at:

https://{}.atlassian.net/jira/servicedesk/projects/{}/settings/sla

which might looks e.g. like:

(the details of filters and metrics values are then available on expanding the sections).

It seems that the following API is called from the Web UI:

https://{}.atlassian.net/rest/servicedesk/1/servicedesk/agent/{}/sla/metrics

which returns the respective data.

I could not find any respective API call in the https://github.com/atlassian-api/atlassian-python-api/blob/master/atlassian/service_desk.py so I guess it is not implemented yet.

It would be nice to have this feature available.
