The Whois XML Contacts API allows users to get full contact information of domain owners based on the data parsed from website content, social networks, SSL certificates, and other sources. The service has coverage of 152+ million websites, 283+ million contacts, and 4+ million websites analyzed daily. The API can be used for data integration, marketing (i.e., gather business intelligence, build marketing applications, get to know customers, etc.), and risk management (i.e., perform background checks, prevent fraudulent activity, etc.).
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
