For device items we use this REST URL:
<DA_Host>:8581/rest/tenant/<TENANTID>/devices/metricfamilysupporthistory/<DA_deviceItemID>
We can use the following URL to determine the necessary <TENANTID> to use. I see in that output for example the Default Tenant ID is 1.
<DA_Host>:8581/rest/tenants
I then obtained a a Device ID. I used the REST URL <DA_Host>:8581/rest/devices/manageable to find the ID. I placed it at the end of the URL:
<DA_Host>:8581/rest/tenant/1/devices/metricfamilysupporthistory/<DA_deviceItemID>
Reviewing the information returned we see both supported Vendor Certification and Metric Families where no Vendor Certification support was found.
This is an example of a Metric Family where no Vendor Certification was found to support. This one is for the Metric Family NormalizedPoolConnectionPoolMemberPVAInfo.

This is an example of a Vendor Certification that was found as supported. It is for the Metric Family NormalizedPortInfo which resulted in support for the IfXTableMib Vendor Certification.

Components
For Component items use this REST URL:
<DA_Host>:8581/rest/devices/components/<DA_ComponentItemID>
As an example I reviewed an Interface item. In the results we see the following. It shows that the interface supports the IfTableMib Vendor Certification.
