  title: Electricity Maps CarbonIntensity Pricing API
  description: The Electricity Maps API delivers real-time, historical, and forecasted electricity grid signals worldwide, including carbon intensity, power breakdown by source, renewable and carbon-free percentages, electricity flows, total and net load, and day-ahead pricing. Each signal is available in three temporality variants (latest, past, forecast) and can be queried by zone identifier, geographic coordinates, or data center provider/region.
