How do you find out if an add-on is incompatible or has an available update via the REST API?

[Logan Hawkes]

I'm writing a tool to analyze installed add-ons in Jira instances and I've hit a wall. How do you determine through the REST API if an add-on is incompatible or has an available update? In the GUI, If I generate a link to the add-on's entry in the Atlassian Marketplace and pull that data, I get a ton more information, but nothing to indicate that an update is available.

For example, in the GUI, the entry for "SSO for Atlassian Data Center" says there's an update available. I have v 4.0.1 installed. The latest is 4.1.0. I don't see anything in the output from a REST call to indicate this. 

GET http://localhost:8080/rest/plugins/1.0/

By the same token, I have Workflow Enhancer for JIRA v3.9 installed. The GUI reports that it's incompatible and an update is available. There's nothing about this in the output from the REST calls:
