Some comps are drastically differently priced in some areas solely on the type of material that is used to build the house. To account for this, we now support using the “same_construction_type” [bool] filter on the input

{
 "id": "252442669",
 "max_radius_miles": 5,
 "max_results": 10,
 "same_construction_type": true
}

When the subject property propertyInfo.construction is “null”, then the filter is ignored and the comps can have any construction type value

if the subject property does have a propertyInfo.construction field, then all comps will have the same value for that field

The construction field is not returned on the comps response object, but is for in the .subject object. If you want to verify, use the property ID of a comp and do the Property Detail lookup
