One call. Instant answers.

One call returns checks for an IP, email, phone, and shipping country — in single-digit milliseconds, typical. Fast enough to sit inline in your checkout or signup flow without anyone noticing.

STEP 1

Your request

POST the fields you have. All optional; at least one required.

STEP 2

Instant checks

Every check family evaluates in milliseconds — no queuing, no batching delays.

STEP 3

Checks + score

Per-check objects, a 0–100 advisory score, and stable reason codes — as JSON, XML, or CSV.

STEP 4

You adjudicate

We return checks. Your rules decide. No verdict field, ever.

Always-fresh data, never in your way

Every check runs against data that refreshes on its own schedule and is validated before it goes live — so your checks stay current and an update never interrupts a request.

Your data is never stored

The values you screen — IPs, emails, phone numbers, names — are processed to produce your response and immediately discarded. They are never written to a database, file, or backup, so there is nothing for us to leak, sell, or lose, and using FraudCheck adds no new store of your customers' data to your compliance surface. We keep only request metadata (timestamps, endpoints, status codes) for billing and reporting. See the Privacy Policy for details.
