Please, do NOT go there. If you are automatically querying somebody
else's service on a regular basis, ASK PERMISSION FIRST.

Yes, doing one query once in a while (eg only once month or so) is
typically quite fine for most operators, they won't be annoyed with that
as heck that is normal behavior; automation is not normal.

The moment though you start automatically querying other people's
services, they will block you or otherwise make sure that you will not
perform that any more.

Greets,
