  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.'

      summary: Elevation API
      description: The Elevation API returns the height above sea level (metres) for any coordinate on Earth, using global SRTM data. Query a single point, a batch of points, or a full route/track for an elevation profile — send up to 100 points via GET or 1000 via POST. Values are bilinearly interpolated for smooth results; ocean returns 0.
