Stop fraudulent payments at the gate
Score every transaction by combining card risk signals, IP intelligence, device fingerprints, and email validation before processing payment.
Card risk scoring
Evaluate card BIN data, issuer country, and prepaid/virtual card indicators before authorization.
Billing address verification
Cross-reference billing details with IP geolocation and email domain to detect mismatches.
Velocity-based detection
Track payment attempts per card, device, and IP to catch systematic card testing.
Real-time decisioning
Return allow, challenge, or block verdicts in under 50ms to avoid checkout friction for good users.

Read StoryUptime guarantee for all API endpoints.
Response time across all endpoints.
Build your own payment fraud rules
Combine email, IP, domain, and device signals into custom rule sets. Use thresholds, allowlists, and velocity counters to match your exact risk model.
Automate your payment fraud response
Evaluate risk and trigger actions in the same API call. No polling, no queue delays.
Inline decisions
Get allow/deny/challenge verdicts in <50ms to enforce policy within your existing auth flow.
Conditional step-up
Trigger MFA, CAPTCHA, or manual review based on risk score thresholds you define.
Webhook events
Push risk events to Slack, PagerDuty, or any HTTP endpoint for real-time team visibility.
Full visibility into payment fraud
Query, filter, and visualize every scored event. Drill down from aggregate trends to individual requests.
Request explorer
Search and filter scored events by risk level, endpoint, IP, email, or any metadata field.
Correlation graphs
Map relationships between accounts, devices, IPs, and payment methods in a single view.
Audit trail
Full request/response logs with timestamps, scores, and applied rules for every API call.
Dry-run mode
Test new rules against live traffic without enforcement. Compare expected vs. actual outcomes.
Layered intelligence for payment fraud
Every API call returns structured risk data. Combine multiple signals for higher-confidence decisions.
Risk scores
0-100 scores per endpoint: email risk, domain risk, IP threat level. Use individually or combine.
Velocity counters
Track event counts, sums, and rates per user, device, or IP over sliding time windows.
Device intelligence
Persistent fingerprints that survive cookie clears, incognito mode, and storage resets.
Bot classification
Classify traffic as human, automated, or headless based on browser signals and request patterns.
