Cisco Prime API- how to retrieve the "AP Limit" for WLC

• Able to use the Cisco Prime API and extract information about the Wireless LAN Controllers. However could not find in the online documentation (https://developer.cisco.com/site/prime-infrastructure/documents/api-reference/rest-api-v3-1/) where is it possible to extract the "AP limit" 
• In the web-GUI of Cisco Prime, there is a section for Administration -->Licenses and Software Updates ---> Licenses. 
• This is a dashboard where it shows the list of Wireless LAN Controllers, the ip address, model, number of AP that is currently registered and the "AP Limit" ... Could get and see all the other information except the last one ("AP Limit") using GetWlanControllers as described in this online documentation (https://developer.cisco.com/media/prime-infrastructure-api-reference-v3-1/192.168.115.187/webacs/api/v1/data/WlanControllerscc3b.html?_docs)
• 
    There is no mention of the "API Limit" or "basically the "license" that tells up to how many Access Points.
  However, this "AP Limit" is visible on the web-GUI of Cisco Prime as a separate column ,

We currently do not support this, unfortunately.  Have forwarded this feature request to our product management team.
