Have you got a list of company names and need the website URLs that go with them? The BuiltWith Company To URL API does exactly that — hand it a list of companies, and it returns the matching domain for each one.

Under the hood, the API scans company names and social links across our entire database, then filters out the noise to find the closest match to the name you provide. Give it "Shell," for example, and you'll get back shell.com. The more established a business's online presence is, the more likely we are to find a confident match — and we only charge you when we actually find a result, so there's no cost for a miss.

Company To URL is also available as part of BuiltWith Pro, where you can upload and manage a running list of companies and get their website domains back in bulk — handy if you're regularly turning company names from a CRM, spreadsheet, or lead list into usable domains.

Try it for yourself at https://api.builtwith.com/company-to-url, or check out BuiltWith Pro for the bulk UI version.
