Up to 1,000 identification API calls per month

Entry terms

99 US dollars per month for 20,000 API calls on Pro Plus

Integration

JavaScript, mobile SDKs, Server API and webhooks

Where Fingerprint fits

Use Fingerprint when recognition is the starting point of the workflow: whether an environment has visited before, what changed, and which Smart Signals apply. Map the returned visitor identity to your account identifier on the server. A visitor identifier is not a verified legal identity.

Collection and outputs

A client agent gathers device information and the platform exposes identification results plus supported Smart Signals. Network indicators, browser tampering, automation and velocity can contribute to a wider assessment. The precise set varies by integration and subscription.

Freshness and integration handling

An identification is an observation at a point in time. Repeat it at the important action and retrieve the result through a server integration rather than reusing an old browser response for every later action.

Strengths

Limits and plan conditions

Check each signal against the chosen plan and platform. Free identification access does not imply every web Smart Signal is included.

What to check in a pilot

Use an established test device, a fresh browser profile, a network change and a native app if mobile is in scope. Record the identification result separately from VPN, tampering and automation signals, and confirm which fields your purchased plan returns.

Use the evaluation framework to record collection completeness, the reasons returned and the customer outcome. Compare the cost of your actual checks, not just the number of accounts in your database.

Consider an alternative when

Your only missing component is an IP dataset or lookup inside an established investigation system. Compare the focused network services on the alternatives page, while retaining authentication and account history in your application.

FAQ

Are Smart Signals included in the free plan?

The pricing page distinguishes free identification from Pro Plus and Enterprise signal access. Verify the exact signal and platform before relying on it.

Is an identifier proof of account ownership?

No. Device identity describes an observed environment. Authentication and recovery still need separate controls.

What should a mobile pilot check?

Test iOS and Android separately. A field documented for one platform is not evidence that the same field exists on the other.
