  version: 1.1.0
  description: 'OSRMRoute — Maps, Routing, Truck Routing, Search, Road Data, Studio and integration APIs. Use `Authorization: Bearer ` unless an operation documents another flow. Legacy APIs also accept the key query parameter; New geospatial APIs, MCP and private map delivery require Bearer authentication. Mobile challenge/token endpoints use device attestation instead. Coordinates and units are documented per operation: GeoJSON uses longitude,latitude; some legacy and background-job inputs use latitude,longitude. Examples are illustrative, not guaranteed current results. Guides · Mobile Access · MCP · Postman collection.'

      description: 'The Isochrone API draws reachability polygons: the area you can reach from a point within a given time budget. Feed it a location and a time limit and it returns a polygon (a coverage area) tailored to the transport mode. Use it for site selection, delivery-zone planning, catchment analysis and ''what''s within 15 minutes'' features.'
