Compute a turn-by-turn route between origin and destination (optionally via waypoints). Costing "auto" = car, "truck" = lorry, "bicycle", "pedestrian" = walking, "motor_scooter" = moped. Pass `truck` {height_m, width_m, length_m, gross_weight_t, hazmat, tunnel_code} to apply dimensional limits and the ADR dangerous-goods tunnel matrix to the search; `pedestrian` {use_lit 0-1, type "wheelchair"|"blind", max_hiking_difficulty 1-6} for lit-street walking, accessibility and trail limits; `bicycle` {bicycle_type, use_roads 0-1, use_living_streets 0-1, avoid_bad_surfaces 0-1, use_hills 0-1} for quiet-ride and surface preferences. Returns distance (m), duration (s), maneuvers, polyline6 geometry and the ADR costing that was applied. Any of truck, auto, bicycle, pedestrian or motor_scooter routes may set `rationale: true` (opt-in, costs up to 1 + N extra routing calls) to learn which declared truck constraints or avoidance-side preferences (hills, surfaces, tolls, unlit streets, …) actually changed the route (`rationale.avoided[]`, basis route_divergence — it proves a field was binding, it does not identify the physical restriction or feature, and no live traffic or incident data is ever attributed). ADR honesty: `applied_adr.forbidden_tunnel_categories` describes the LOAD, not the returned route, and `applied_adr.tunnel_enforcement` states the boundary: roads are excluded only where the routing graph records an ADR tunnel category, so an unchanged route is not a clearance. Set `landmarks: true` for turn instructions anchored to recognisable places — each manoeuvre that passes one gains a `landmark_instruction` like "Turn right just after the Shell garage" beside the engine's own street-name `instruction`, which is never replaced. Prefer reading it aloud: it is how a passenger gives directions. Nothing is named unless it is recognisable from the road, within 40 m of the junction and not tagged as closed, so many routes return none and a `landmarks.annotated` of 0 with no `note` means this route genuinely passes nothing recognisable. Needs the MapMap gateway (GATEWAY_URL + GATEWAY_API_KEY), whose place index does the lookup. Optional `exclude_polygons` for what-if scenarios ("close this bridge and re-route"): an array of polygons, each an array of [lon, lat] pairs forming one ring — longitude FIRST — whose intersecting roads are excluded from the search. Applies to the Valhalla engine; unsupported on the GraphHopper engine, where it is ignored.
