  title: OpenRouteService Directions API
  description: OpenRouteService is a free, open-source geospatial API platform built on OpenStreetMap data. It provides routing directions for multiple transport modes, isochrones for reachability analysis, time-distance matrices, geocoding, elevation data, points of interest, and vehicle route optimization for logistics and humanitarian use cases.
