# The Route Range API creates a polygon that depicts the area reachable from a given location within a certain threshold based on the specified time or distance budget.

`POST /route/range`

A polygon boundary (or Isochrone) is returned in a counterclockwise orientation as well as the precise polygon center which was the result of the origin point.

The returned polygon can be used for spatial filtering to search for features of interest within the provided Isochrone.
