HTTP Bridge Endpoints on demo instance

Does the demo instance at demo.crossbar.io have endpoints for http bridges and, if so, what’s the url?

I have crossbar working alongside and app I’ve written using https://anvil.works and I’d like to publish a demo to showcase it on the anvil forum. However, it uses http bridge calls and I can’t find anywhere whether there are endpoints for those on the demo crossbar instance.

Thank you
