Payment fraud analysis

Send the order, customer and payment details and get a 0–100 fraud score together with the exact rules that fired — velocity, mismatched geolocation, risky countries, disposable emails, reused cards and more. Card numbers are never stored: only the BIN, last four digits and a keyed hash.

What it detects

  • High purchase velocity per IP and per customer
  • VPN, proxy, Tor or hosting traffic at checkout
  • Billing / IP country mismatch and high-risk countries
  • One card used by many accounts, many cards by one account
  • Disposable or invalid email and phone number
  • Your own blacklists and custom rules
