getArea

Filter the results to regions that intersect with a specified area.

The area may be defined in one of two ways: * radius,region_id * radius,latitude,longitude Radius combined with region id would search an area that extends the number of kilometers out from the boundaries of the region in all directions.
Radius combined with a single point, specified by a latitude, longitude pair would search an area in a circle with the specified radius and the point as the center.
Radius should be specified in non-negative whole kilometers, decimals will return an error. A radius of 0 is allowed.
When specifying the area parameter, there will be a limit of 100 results, which can be narrowed further by the limit parameter.
Due to the number of results, unless point_of_interest is specified as the only type, regions of type point_of_interest will not be included in a request that filters to an area.

An example use case would be searching for the closest 3 airports within 50 kilometers of a specified point.
