Validate this idea: Third party API Caller

Yes, You heard it right. It's a service that helps you call third party API on your behalf. Or, API as a service where you can call the third party at timely manner.

I created this already for my side projects and used it for my previous projects. So saasing this easy for me but wanted to get your perspective on this matter.

Take a look at this Twitter example. To post update on Twitter your app only allowed to call 300* per user; 300* per app. If you exceed this limit then twitter throws an error and resulting breaking user experience.

So I thought why not create a service that can take care of this third party API calling easy as pie.

Let me know your thoughts on this matter.
