Quickstart: Your First Voltpath API Request

This guide walks you through making your first request to the Voltpath API. In a few minutes, you will retrieve day-ahead electricity prices for Germany for the past seven days and understand how the API structures its responses.

Choose your base URL

The Voltpath API is hosted at the following base URL. No API key or authentication is required based on the current specification.

https://api.voltpath.ai

Fetch day-ahead prices

Send a GET request to /api/v1/prices with query parameters to filter by bidding zone, time range, and resolution.

curl 'https://api.voltpath.ai/api/v1/prices?zone=DE&datetime_from=now-7d&datetime_to=now&resolution=1D'

import httpx

resp = httpx.get(
    'https://api.voltpath.ai/api/v1/prices',
    params={
        'zone': 'DE',
        'datetime_from': 'now-7d',
        'datetime_to': 'now',
        'resolution': '1D'
    }
)
print(resp.json())

Read the response

All Voltpath endpoints return data inside a standard envelope. The meta object contains provenance information, the resolved time range, and upstream data sources. The data array holds the result rows.

{
  "meta": {
    "provenance": "measured",
    "resolution": "1D",
    "resolved_datetime_from": "2026-08-19T00:00:00",
    "resolved_datetime_to": "2026-08-26T00:00:00",
    "upstream_sources": ["ENTSO-E Transparency Platform"]
  },
  "data": [
    {"datetime": "2026-08-19T00:00:00", "bidding_zone": "DE", "price_mwh": 82.45, "interpolated": false, "year": 2026},
    {"datetime": "2026-08-20T00:00:00", "bidding_zone": "DE", "price_mwh": 79.10, "interpolated": false, "year": 2026}
  ]
}

Each row in the data array is a PriceRow containing the timestamp, bidding zone code, day-ahead price in EUR per MWh (price_mwh), an interpolation flag, and the year.

Filter by multiple zones

To retrieve data for more than one bidding zone, repeat the zone query parameter for each code.

curl 'https://api.voltpath.ai/api/v1/prices?zone=DE&zone=FR&datetime_from=now-7d&datetime_to=now&resolution=1D'

Use resolution=auto (the default) and let the server select the most appropriate granularity for your requested time range.
