What is Elecz?

Elecz turns real-time electricity prices into actionable signals — for AI agents, home automation, and anyone whose decisions depend on when they use electricity.

A language model cannot know the current electricity price. It was trained on historical data. Without a real-time API call, any answer it gives is a guess. Elecz is that call.
