Have you got a list of company names and want the website urls associated with them? You can now use the BuiltWith Company To Url API to do just that.
The API looks at company names and social links that we index across our entire database, then filters out all of the junk to try and find the most similar match to the company name you provide. I.e. if you have the company name ‘Shell’ we’ll return shell.com as the website. The more “internet friendly” the business is the more likely we’ll find a company name for it. We’ll also only charge the result if we find something.
