Api returns empty XML


I am trying to call api for map info:

It return no errors, but xml is empty.

How can I found the reason?


No the document is not empty. The content is:

<?xml version="1.0" encoding="UTF-8"?>


You will not get nodes, ways or relations as you did not define an area. Your maxlat==minlat and maxlon=minlon, so you defined a point.
