Auto-Detecting an XML API

I have a Scientology blog over at xeeks.com (www.xeeks.com/scientology) which I started a while back, but literally just dumped because of the fact that I couldn't figure out a way to use any of these nifty app-type clients like Flock or LiveWriter to be able to write to the blog.

It's so much easier to be able to just be surfing along and just hit one hotkey and blog about it, than it is to have to go to some website and log in and then start typing.  It stops being a natural extension of your communication cycle, and instead is something else you have to remember to do sometimes. 

Does anyone know of a way to be able to take a regular old blog like this Xeeks blog and find out how to detect its XML API?
