Can you rephrase the question? I’m guessing one of the reasons you’ve  
received no replies is that it’s not at all clear what you’re really  
looking for.  
If you’re simply looking to get started with Rails, there are many  
good replies in the archives of this list.

But an API of a Rails app, with or without unique private keys and  
stuff, doesn’t really make sense to me.

I have build an app. I just want to create an for basic CRUD operations  
so that external apps can communicate with it.

Like Twitter API you can use to update your status and stuff.
