Convert JSON to RSS via Web API?

Question

I would like to create a generic Web API action that will accept a JSON URL as a parameter, then convert it to RSS. Everywhere I look I find RSS to JSON but not the other way around.

I did not want to use a 3rd party service but instead looking for a library that can do this. Any idea on how to leverage Web API to do this or should I just create a simple HTTP Handler for this?

Answer 1

You could implementing your own RSS or Atom custom MediaTypeFormatter. You can implement it so that the request will use this formatter when the accept header is set to application/atom+xml or application/rss+xml.

Filip has a blog describing this: RSS & Atom MediaTypeFormatter for ASP.NET WebAPI

Answer 2

Superfeedr provide a feed API which does RSS to JSON conversion both when you poll feeds and when you want to be notified for changes in them.
