I have created many mashups using "Capability APIs" (JavaScript Version). I am interested in finding out if there is any .Net API (server side) to fetch charts from Qlik apps and show on Web-Pages.
Not really. All rendering is always done by JavaScript, so no matter what you do you will always have to go through that layer somehow. But you can of course produce the relevant links for showing charts in a browser component. That is how the chart preview feature of this tool is implemented: Qlik Explorer for Developers
