The Travel Boundary API uses the concept of an isochrone which is a path that joins all the points with the same travel time or travel distance from a reference location. It calculates the regions that can be reached within a designated time or distance from a given location. It returns these regions as contours in the form of polygons or lines, which can be displayed on a map. With this API, you can define serviceable areas or delivery zones based on travel times or distances from a starting location.
This API can be accessed through the HTTPS GET method.
