 PowerAPI is a middleware toolkit for buidling software-defined power meters. Software-defined power meters are configurable software librairies that can estimate the power consumption of software in real-time. PowerAPI supports the acquisition of raw metrics from a wide diversity of sensors (*eg.*, physical meters, processor interfaces, hardware counters, OS counters) and the delivery of power consumptions via different channels (including filesystem, network, web, graphical). As a middleware toolkit, PowerAPI offers the capability of assemblying power meters *«à la carte»* to accomodate user requirements.
