About WattBuy
WattBuy provides a REST API suite for energy-related data and services, described as a "Personalized Power Platform" aimed at enterprises building customer-facing energy experiences. The APIs return JSON-encoded responses and use standard HTTP response codes and authentication.
The suite covers electricity utility information lookup, usage and solar estimates, carbon footprint estimates, ESI ID lookup, retail and surplus generation rate databases, and property-level electricity details. It also includes endpoints for residential incentive programs, offers and marketplace deeplinks, form fields, offer enrollment submission, order status, deregulated plan credit checks, and EV charger installation requests. A WattBuy MCP server and widgets are also referenced as part of the platform.
This is intended for developers and enterprises integrating electricity data, rate comparison, and energy offer/enrollment workflows into their own products.
