This API takes in latitude and longitude and returns the corresponding zip,city,state timezone, dst. It is more accurate and multiple orders faster than reverse geo-coding because it considers zip boundaries(polygons) rather than find the nearest address and then derive the zip from that. i.e Reverse geocoding on parks, highways may not return the zip if there are no addresses in range of 50 mts. However, this API examines if the latitude, longitude is within a zip polygon.
