**APIs profiled:** 8

Axle Energy operates a virtual power plant (VPP) platform that connects distributed energy assets — electric vehicles, EV chargers, home batteries, and heat pumps — to electricity flexibility markets through a single unified API. Partners (carmakers, charger and battery OEMs, HVAC suppliers, and utilities) register sites and assets, prequalify and enrol them in flex propositions, stream telemetry and plug/charge events, and let end users monetise shiftable demand. The API covers authentication, meter lookup (MPAN), sites, assets, telemetry/readings, rewards/payouts, validation, and half-hourly price curves, with markets live across Great Britain, France, Germany, the Netherlands, Denmark and Sweden. React/hosted UI components and a documented outbound dispatch webhook round out the developer surface.
