USADATA, Inc.

USADATA Leads Engine Service (SOAP)

Publicly served SOAP 1.1 / 1.2 web service behind the USADATA Leads Portal and Leads Module. The WSDL is served anonymously from the production API host and declares 24 operations covering the full list-brokerage workflow: table and column discovery (getTableList, getTableDefinition), synchronous and asynchronous audience counts and saturation (carrier-route) counts, cross-tab matrix reports, prior-order suppression, order pricing, order submission, order status and cancellation, address lookup with geocoding, and state/county/city/ZIP geography lookups. Authentication is a Login {UserID, Password, ClientID} element carried in the SOAP body; ping and getVersion answer anonymously. Credentials are issued by USADATA through sales / developer support — there is no self-service sign-up.
