BizAPI
BizAPI Company Search API

Real-time business data append API. Submit a partial business record — company name and address, phone, website or DUNS number — and BizAPI matches it against the Dun & Bradstreet business database, returning NAICS and SIC classification codes, address and contact data, employee and sales figures, and the corporate family tree. One POST operation plus a credit-free sandbox twin, HTTP Basic auth, billed per successful match.
