Yes, it is a dialplan app.  So, you have to call it from a dialplan.

If you don't want to bounce through the XML Dialplan, you can use an
inline dialplan instead and specify the dialplan on the originate
commandline.  The wiki has an example:

realm and id are just arbitrary strings.  They can be useful if you
want to do reporting out of the database (if using regular limit api,
for limit_usage it wouldn't apply).

You can provide your own meaning to realm and id.

In a multi-tenant setup, you might use domain as the realm but that
isn't necessary.
