How is the score calculated?

It combines VPN, proxy, Tor, hosting and abuse signals into a single 0–100 value. Each factor is also available individually if you prefer your own weighting.

Can I get the score via API?

Yes — query the IP and use the returned signals to compute or read a fraud score in your backend.

Yes, with 100 free lookups per month before any paid plan.

IP Fraud Score

Turn the signals behind an IP into a single fraud risk score from 0 to 100, so your rules can act on one number.

Overview

What is an IP fraud score?

An IP fraud score condenses everything risky about an IP address — VPN, proxy and Tor usage, datacenter hosting, and any history of abuse — into a single number from 0 to 100. A low score suggests an ordinary residential visitor; a high score suggests anonymised or abusive infrastructure. It lets you write simple rules (“review orders above 75”) instead of juggling many separate flags.

Signals

How the fraud score is built

Each signal contributes weight to the final 0–100 value.

Anonymiser usage

VPN, proxy and Tor each add risk.

Hosting origin

Datacenter and cloud IPs score higher than residential ones.

Abuse history

Known bad behaviour from the range increases the score.

Geo consistency

Mismatched location signals raise suspicion.

Velocity

Unusual request patterns from the IP add weight.

Single 0–100 score

All signals roll up into one tunable number.

It depends on your tolerance, but many teams allow low scores, challenge mid-range scores and block or review high scores. Start conservative and tune from your own data.
