Use cases
Where a trust check belongs in your flow, and what changes depending on where you put it. Screening at signup, at login, before a payment, or over a list you already have.
Signup fraud prevention
One call at account creation, before the account exists to defend.
Email & phone list cleaning
Validate an existing list before you send to it or dial it.
Account takeover protection
Score the login, not just the signup — the attacker arrives later.
Pre-payment screening
Filter obvious abuse before it reaches your payment processor.
