The Daisycon energy API provides all the Dutch energy pricing information for customers, of course including a URL so customers can sign-up with the energy provider of their selection. Required fields are (of course) your publisherID and the house address of the customer. Better predictions of the total costs for customers can be calculated when expected usage of gas and electricity is also provided.
If you don’t want to build an energy calculator yourself but do want to offer this service, you can also use the Daisycon energy tool using vergelijkers.daisycon.com
The above energy API service is currently running in Beta version. If you have any questions or feedback, please contact [email protected]
