If you need that feature, and are willing to pay, check out the Demandbase API. I can't find any public websites documenting their API, but this Ruby gem gives an overview: https://github.com/leereilly/demandbase.
Andrew from Clearbit here. You can definitely search by domain using our Company API (http://clearbit.com/docs#company-api). Is that what you are looking for?
