Find SEO ranking of a website a keyword with API

Is there any API that can be used to find the Page of Google or Yahoo etc search engine of a particular URL with respect to a particular Keyword?

I am to use C#.NET.


Hi Sovan,

I also have a need for that. The only service till now that I have found is
the ranking solution from and then their enterprise version. I am not affiliated in any way to Authoritylabs.

If you find another party then I would like to hear from you.


Is there no way?

Just found who also provide an API for rank checking. Again; I am not affiliated to them.
