Endpoints include current GSI values, regional breakdowns (for select areas), and time-series data for trend analysis. Responses are in JSON format, supporting integration into smart home systems (to optimize energy use during high renewable periods), eco-conscious apps, or sustainability research tools. It caters to personal and non-commercial use with free basic access, enabling users to align energy consumption with green power availability.
