One of the issues here is that there's no obvious alternative to switch to in most cases. Plus depending on a well-established company like Heroku (Salesforce) or Amazon is different then depending on something brand new.

Not to diminish the work put into this though. It looks great! :)

[NeutrinoAPI]

Well we all have to start somewhere! =) Plus we already have loads of happy customers that have been using some of our older APIs for more than a year now. Further to this, defensive programming goes a long way when working with APIs (both local and remote APIs). You should design your app in a way that it can continue to function even if an API malfunctions.
