AtData's Fraud Prevention API delivers comprehensive insights into each email address' risk and fraud correlation. Leveraging the extensive data gathered from billions of monthly activity events, our comprehensive historical email database, and a robust fraud consortium database, this API equips you with the detailed information needed to enhance your fraud prevention strategies.

Retrieving Fraud Prevention Data

The Fraud API is the primary Fraud Prevention API from AtData. It allows you to input a user's email and associated details to retrieve comprehensive information about their fraud risk. This data helps you make informed decisions to protect your system from fraudulent activities.

To use the Fraud API, add your API key as a query parameter to the endpoint's URL and the email you want to verify. This is exemplified below:

https://api.atdata.com/fr?api_key=<YOUR_API_KEY>&email=<EMAIL_TO_VERIFY>

Remember to replace <YOUR_API_KEY> with the API key created in Getting Started's Step 2, and <EMAIL_TO_VERIFY>with the actual email you need to verify. The recipe below shows an example code using Python to perform this request:

URL encoding
