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 sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it.
