With version 1.4 of activeRenderer, its rendering engine becomes reachable over HTTP, by sending a GET request to either 127.0.0.1:5335/activeRenderer/render - the local URL if you have both Radio Userland and activeRenderer installed - or services.activerenderer.com/activerenderer/render - the new public URL for the activeRenderer web service.

In both case, you need to add a ? after the web address, and specify at least 2 parameters.

• src is the local or remote URL of the source OPML outline or RSS feed
• action is the operation you want to perform. The only legal value currently is render.

First example: http://services.activerenderer.com/activeRenderer/render/?src=http://www.scripting.com/rss.xml&action=render

Second example: http://127.0.0.1:5335/activeRenderer/render/?src=http://radio.weblogs.com/0104487/gems/aR/activeRenderer.opml&action=render - works only if you have Radio and activeRenderer installed.

There are a bunch of parameters one may specify to modify the way outlines are rendered with activeRendererer. I guess I'll have to come up with a tutorial VIII in a not too distant future. In the meantime, you may try several by clicking settings in the outline browser.

I'm planning to add XML-RPC and SOAP support to the activeRenderer service in a coming update version.
