Overview
What the Email Fraud Check API Does
FinHub's Email Fraud Check API scores an email address against reputation history, breach exposure patterns and structural red flags, freshly registered domains, throwaway providers, high-risk TLDs, to catch synthetic identities and account-takeover attempts before onboarding completes. Every score is generated under consent and sealed to a tamper-evident audit log.
