VoltPath gives you programmatic access to European electricity market data: cross-border power flows, day-ahead prices, and the derived metrics built on top of them. Every endpoint is an HTTP GET that returns JSON, ready to drop into a dashboard, analytics pipeline, or trading model.

​
What you can query

  • Prices — day-ahead electricity prices per bidding zone
  • Flows — cross-border power flows, classified by type (convergence, congestion, counter-intuitive, outage)
  • CI share — how often flows run counter to price signals, by zone or border
  • Import / export — net energy moved in and out of each zone
Browse the sidebar for the full endpoint list, or see Flow Types for how classification works.
