Fuel price data API

The complete site renders without the API. Download the latest static snapshot or the region index.

Public endpoints

• GET /api/latest: latest exported regions and update time.
• GET /api/region/{id}: one region, for example eu-dk.
• GET /api/history/{id}?weeks=52: weekly gasoline and diesel history. Weeks must be an integer from 1 to 260.
• GET /api/compare: available prices in local currency and USD/L.
• GET /healthz: export freshness and data age.

The optional Worker uses a separate configured API origin, recorded in the API connection file. Static downloads above are available even if that service is unavailable. Responses use JSON, open CORS and up to one hour of edge caching. An unknown region returns 404. Missing data is null, never zero.
