With the WOZ API, you will be able to fetch the latest WOZ values for each property in Netherlands.
Every year, every municipality determines the value of houses, business premises, shops, and unbuilt plots. This value is called the WOZ(Waardering Onroerende Zaken) value. The municipality uses the WOZ value to determine the amount of taxes. With WOZ API, Altum AI creates a unique and simple modus operandi for retrieving WOZ Values for homes and properties in the Netherlands. The source of the WOZ values is the official WOZ Website. This model will provide values for properties with either BAGID or House address as long their WOZ Values exist on the WOZ Website. The WOZ API also provides other details in its response like the Build Year, Coordinates, Purpose of property, etc.
For the WOZ API to be able to deliver the WOZ value and object details, the object details such as the zip code and house number or BagID has to be present.
Depending on the object and input, we generate a response. This response covers the details about the property such as the address, building type, building year, outer surface area, and other correlating information.
