Got some more Caffeine and realized the error in my ways. I wasn't drilling deep enough into the api/json/v2/types/tags/ item. I found that my list of volumes is right there under direct-list. [IMAGE]
Please excuse me if this is something I should already understand. I am very new to using REST API and I am able to get a volume list or the details for a volume. I have figured out how to filter for volumes that match a specific size, etc. The issue I am having is trying to search or filter for volumes that have a specific tag. Does anyone have an example of how this could work.  I am working to build a workflow in Cisco UCS Director and I need to find all the volumes for a specific ESX cluster so I can map them to a new host being added to the cluster. Since there is no "Storage Group" concept (like in our VNX/VMAX) I was looking at using Tags to do this. If someone has a better idea, feel free to chime in.
