How to add an open API to a Rails application?

Question

I would like to open the Rails 2.3 application (hosted on Heroku) for developers. I thought of two ways of doing this:

• Using response_to | format | applications, and before_filter allows authorized API API keys
• Using Heroku's second API account, sharing the original application database. Now, what would be better: Rails, Sinatra, or Grape ?

I know this is a vague question. Do you have any good articles or architectural patterns that could help me?

Thank,

Kevin
