  title: Electricity Maps API
  description: >-
    The Electricity Maps API serves electricity grid carbon intensity and power
    production/consumption breakdown data for 200+ zones worldwide, in real time,
    as 24-hour history, and as 24-72 hour forecasts. It is the same data behind the
    live map at app.electricitymap.org. All data endpoints require an API key passed
    in the auth-token header; the zones and health endpoints can be called without
    a key.
