I think you misunderstood me.
the admin/stats.xml file *is* the API interface. It's for usage such as
yours. within /admin: stuff ending with .xsl is for non-API, stuff with
no dot in the name or ending in .xml are for API usage.
What you will get is a well formed XML document. Have a look at it!

No. I think you are misunderstanding the standard here:
Icecast is *not* refusing to serve the resource. So it MUST return a
2xx-status code. The fallback isn't happening in the protocol layer.
(This is because there are no mid-of-stream redirects on HTTP. So
redirects (3xx) can't work for users already connected.)

Again, see my hints on the admin/stats.xml file. It contains all the
data you want.
