Degree days API documentation
Full API reference for integrating degree day calculations into your systems.
The Energy Data API
Our database and the calculation of heating and cooling degree days and weather normalization are available via an API. Energy managers, developers, and integrators can embed these calculations in local software, EnMS platforms, or spreadsheets.
To request data you need a valid API key, which you receive through our subscription service.
Setup
Customers use the API across many stacks: professional EnMS platforms, in-house code, and Excel. We can provide technical support during initial setup.
Test our API
You can test the API without obligation. Book a subscription, use the full feature set, and cancel within 30 days for a full refund if the service does not meet your expectations.
