Turn your AI assistant into a fuel price expert for Germany.

Every gas station in Germany is legally required to report price changes to the Market Transparency Unit for Fuels (MTS-K) at the Federal Cartel Office — in real time. This server connects your AI directly to that data stream via the Tankerkönig API.

Who it's for

Drivers & commuters — find the cheapest E5, E10 or diesel around any address before you leave
Fleet & logistics teams — compare prices along routes and cut fuel costs across vehicles
Analysts & developers — pull live price data into workflows, reports and applications

Example queries

"Cheapest diesel within 10 km of Munich city center"
"Compare E10 prices around Hamburg Hauptbahnhof"
"Is fuel cheaper near the airport or downtown Frankfurt?"

Tools

find_fuel_at — search by exact GPS coordinates

Results are sorted cheapest-first and include only stations that are open and reporting current prices. Search radius 1–25 km. Fuel types: E5, E10, diesel.
