Is it possible to fetch partnumbers present in OID-1 but not present in OID-2 in single API call?

let expand="Components($expand=Part($select=ID,Number),PartUse($select=ComPolarisindPolarisIndustriesEngineeringSequences);$levels=max)";
let Json = Things["Polaris.Windchill-Odata-Connector"].GetPartStructure({
$expand: expand /* STRING */,
ID: PrevOID /* STRING */,
$select: undefined /* STRING */,
NavigationCriteria: undefined /* STRING */
});

Iam using the above code in thingworx to fetch windchill data for the oid. I have to compare data of two different oid. Is it possible to fetch the partnumbers which is present OID-1 but the same partnumbers which is not present in OID-2 in single API call???
