Huntsville Utilities does not publish an official public API for meter or billing data. The NISC SmartHub platform exposes an undocumented internal API that has been reverse-engineered by the community (e.g., the electric-usage-downloader project). For sanctioned access, the recommended path is Green Button file sharing or a direct agreement with the C&I department.
