Overview

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.
