The IPInfoDB E-Commerce Fraud Detection API compares shipping/billing information with IP geolocation data for all countries. For USA and Canada, the API also confirms area code and postal/zip code information. It is very flexible, and parameter weights can be set manually. For example, specify whether, if the IP is in the Spamhaus blacklist, the weight of importance of this factor should remain at #2, or specify whether to keep as #1 importance that the email address provider is a free email service.
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.
