Payment Card Exposures API

Query the Enzoic database of compromised payment card numbers to reduce fraudulent payments

Enzoic recovers information on thousands of compromised payment cards every day, typically when fraudsters are still in the initial stages of testing the card for validity, prior to using it for fraudulent payments. The cards are logged into our database within seconds of being recovered, making our data an excellent source for intercepting and shutting down fraudulent payment attempts.

Enzoic's Payment Card Exposures API allows you to query this data in real-time, using a k-anonymity approach to avoid the need to send a complete card number. By sending only the first few digits of a card number you wish to check for compromise, we can return a list of candidates from our database which you can then compare locally to the full card number to assess whether the card number you're dealing with has been exposed and may be at risk for fraudulent usage.

A single, lightweight API call prior to processing a payment could potentially reduce fraudulent transactions by an order of magnitude.
