cheapest_fuel_along_route

ai.mapmap/mapmap · Verify this server

Find the cheapest fuel along a route, with the REAL extra travel time of stopping at each station — never a straight-line guess. Provide `origin` + `destination` (a route is computed) or an existing route's `geometry_polyline6`, plus a `fuel` code ("diesel" default, "petrol_95", "petrol_98", "premium_diesel", "e85", "lpg") and `max_detour_minutes` (default 10). Stations come from the live open-data price feeds (UK CMA retailer scheme and/or the statutory Fuel Finder, FR prix-carburants, DE Tankerkoenig; the response's `fuel_attribution` names the ones actually matched), are priced through the routing engine with your costing (a `truck` profile makes detours respect dimensional/ADR restrictions) and ranked cheapest first. Each result carries price {value, currency, updated_at, stale} (stale = not verifiably fresher than 24 h), detour_minutes/detour_km, and saving_per_litre vs the cheapest on-route baseline (pass `fill_litres` to also get saving_total). Requires the MapMap gateway; answers a clear error when the deployment has no fuel-price dataset. Display the returned fuel_attribution with the prices.
