vSphere API to check VAAI and VASA provider installed and enabled ?

Hi,

I want to know if there is an API available (VMware vSphere Web Services API) that one can use to identify if the

1. VAAI plug-in / Hardware Acceleration is "Supported" for specific datastore

AND the

2. VASA plug-in is "Supported"/"Installed" for specific datastore/host

If there is no such API available (VMware vSphere Web Services API); then is there any configuration setting for any Managed Object that can be checked for deriving this information

Thanks in advance.
