# Voltpath API: European Electricity Flow and Price Data

> Voltpath delivers European day-ahead electricity prices and derived power flow data across ENTSO-E bidding zones via a fast, modern REST API.

Voltpath provides electricity flow and day-ahead price data across European bidding zones. The REST API is built on FastAPI and sources price data from ENTSO-E, returning derived power flow computations together with rich metadata. This documentation will help you make your first request, understand core concepts, and integrate the seven primary data endpoints into your own applications.

## What you can query

The Voltpath API exposes seven GET endpoints under `/api/v1/`:

* **Prices** (`/api/v1/prices`): Day-ahead electricity prices per bidding zone, sourced from ENTSO-E.
* **Flows** (`/api/v1/flows`): Derived power flows computed from prices and scheduled exchanges.
* **Flow type summary** (`/api/v1/flow-type-summary`): Daily percentage breakdown of flow types per border.
* **Flow duration** (`/api/v1/flow-duration`): Flow duration curve data for analyzing flow distributions over time.
* **Flow vs price scatter** (`/api/v1/flow-price-scatter`): Correlation scatter data linking net flow to price delta.
* **Counter-intuitive share** (`/api/v1/ci-share`): Daily counter-intuitive flow share per zone in hours and percentage.
* **Zone import / export** (`/api/v1/zone-import-export`): Aggregated net import and export totals per zone in GWh.

<Note>
  All timestamps are returned in UTC. The `datetime_from` and `datetime_to` query parameters accept ISO 8601 values or relative shorthand such as `now`, `now-30d`, `now-1H`, and `now-15m`. The response `meta` object includes `resolved_datetime_from` and `resolved_datetime_to` so you always know the exact interval that was queried.
