QUESTIONS

How is the distance measured?
Straight line between the two ZIP centroids, along the curve of the earth. Not a driving route.
Miles or kilometers?
Both, on every answer.
Can I do this from code?
Yes. This page is GET /postal/{code}/distance/{other}, running from your browser. Same endpoint on every plan, one pooled request per call.
What about postal codes outside the US?
The API covers every country that ships coordinates, nine so far. This tool speaks ZIP, and the endpoint takes a country parameter for the rest.
