Fuel Prices France

French filling stations declare their own prices on the national open data portal of the Ministry of the Economy, and the feed is refreshed several times a day. The app reads it directly, with no account and no API key, and follows either the best station within a radius you choose, or one specific station whose price history reads as a curve. The lowest price is not always the best one: the app subtracts the fuel burnt on the detour and picks the station on the net saving. Coverage is limited to France, because that is the extent of the dataset. This data is open and free, published under the Licence Ouverte.
