API license

For the API for on-demand retrieval of building data with individual calculation, we offer a pay-per-use licence model where you only pay for the requested buildings. You are only charged once for each building, even if several solar calculation variants are performed (e.g. for different modules or load profiles), provided that no fundamental recalculation of the building is required due to new 3D surface data.


The pay-per-use licence model is based on credits that have to be booked in advance. Each credit package is valid for a period of one year. The minimum order is 20,000 credits per year. Both the data research and data maintenance efforts as well as the technical efforts for the provision and maintenance of the API are already included in the credits. The required number of credits per building queried depends on the respective size of the building footprint and is divided into four levels. You can decide yourself up to which roof area size the API should be available. In this way, you retain full cost control. You have access to the API usage statistics at any time.


The price per credit is max. 0.25 EUR (plus VAT). The minimum purchase is 20,000 credits.
