Api referenceEnergy
Get your energy contract and household
What Joulo knows about your home: the energy contract (supplier, dynamic or not, the supplier markup and standing charge, your own fixed tariff), and the household answers from the dashboard. Null means you did not answer. A field in inferred_fields is Joulo's estimate, not your answer. Your addresses are not here: they sit behind their own scope, at /locations. Requires the profile:read scope.
AuthorizationBearer <token>
API token from the Joulo dashboard, or an OAuth2 access token.
