The service provides a programmable XML interface for detecting web visitors routine requests through any type of proxy server, which often indicates attempts to circumvent blocks on traffic from particular locations or addresses. This fraud detection function alerts e-commerce applications to traffic with origins masked, helping to avoid costly chargebacks and other bad results of online frauds.
API methods support submission of a requesting IP address discovered in the header of an HTTP request. The service then checks on the authenticity of that address and returns status information indicating whether or not it involves redirection through a proxy, based on a database updated hourly of proxy IPs.
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.
