Learn more about WebCatalog Desktop

Kaidn is a fraud detection platform that helps online businesses assess risk across signups, logins, checkouts, and payouts. Its API analyzes account and transaction signals, then returns an allow, review, or block decision with a plain-language explanation to support fraud prevention and case review. Kaidn helps identify fake signups, account takeovers, card testing, promotion abuse, and suspicious cash-outs. Checks can use information such as email addresses, IP addresses, phone numbers, user IDs, and device signals. Developers can integrate the fraud scoring API using the Node.js SDK, REST, or a browser tag, and can also submit batches of events for analysis.
