afaik, there are no APIs exposed for VUM, what you're seeing with the HostPatchManager is the ability to patch individual hosts specifying a local repo and primarily this was a function for ESXi but should also work for classic ESX

With the latest version of vCLI, you have two commands vihostupdate for ESX(i) 4.0 and vihostupdate35 for ESX(i) 3.5. The command allows you to query, scan install or list the bundles/patches that have been applied against a specific host but it does not have capabilities such as checking it against a baseline created using VUM. You would be manually downloading a set of patches and that is what you would consider your 'baseline'. Both of these scripts are implemented using vSphere SDK for Perl and are installed as part of the vCLI, you can take a look at the source for further questions.

I've heard VUM APIs are coming but not sure when
