Simple Meter Read for multiple meters on Device Cloud

I want to schedule monthly meter read from Device Cloud.
Get /ws/XbeeAttributeDataCore yields the info but I can’t find how to use this Command. Does it need to be in XML format to be scheduled?
If so, how do I nest Smart Energy commands in SCI and RCI?
Having a hard time finding an example of what seems to be a pretty basic request.

Try the following from a web browser

You will be prompted for your Device Cloud Credentials.

For SCI/RCI examples, look under the Documentation > API Explorer > Examples > Smart Energy from your Device Cloud account.
