 ```
 https://<nextcloud-fqdn>/ocs/v2.php/apps/serverinfo/api/v1/info
 ```
 
+- To request the information in JSON append the url parameter `format=json`
+- Use the url parameter `skipUpdate=true` to omit server updates.
+- Use the url parameter `skipApps=true` to omit app updates (including available app updates will send an external request to the app store).
