Hi Lionel,
To get the number of calls recorded, you can use the conversation details endpoint https://api.mypurecloud.de/api/v2/analytics/conversations/details/query, with the required segment filters in the request body.
To get the list of people who viewed a particular recording, you can use the Audit APIs offered under quality management. You can also view this in the UI under the 'Audit Trail' tab in Interaction Detail view of individual conversations.
Thanks and Regards,
