Is there a backend interface to bugzilla?

[jose at invisiondns.com]

I would like to integrate my app with bugzilla but prefer not to use the
generated html output from bugzilla.  Is there a backend interface to
bugzilla where I can just post queries and get plain text responses that I
can parse and display as I need?

If not, I'll be adding such interface to bugzilla, let me know if you would
all be interested and I'll submit my changes.
