AVM API

Sustainability advice and Ecovalue
The sustainability data from Altum AI offers companies insight into which sustainability measures are needed to increase the energy rating of a home. In addition, Altum AI calculates which investment is involved and what the return and payback time is for the homeowner. On the basis of this information, companies can better convince and inform their customers and prospects about the benefits of sustainability and make cross-selling and upselling easier.
Sustainability API
WOZ values
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.
WOZ API
Auto suggest objects and address details
