Do you know any API?

Do you guys know any API to in which I can pass the domain and it tells me if the domain is registered on godaddy or not. I don't want any thing to be available to buy or not. It's okay to not be available to buy even.

No need for an API, just a standard whois will tell you a domain's registration details - and if it's registered with Godaddy you'll see it in the registrar url/data.
