Is this signup real?

Paste an IP address, email, phone number or domain. You get the same answer the API gives, explained in a sentence. No signup, no card.

What this does and does not tell you

A high score is not proof of fraud, and a low one is not a guarantee. These are signals about the infrastructure a request came through — whether an address is a datacenter, whether an email domain is disposable, how old a domain is. Plenty of honest people use VPNs, and plenty of fraud arrives from an ordinary home connection.

That is why LayerCall returns allow, review or block rather than a verdict on a person, and why the middle option exists. Most of what looks risky is best answered with a one-time code, not a closed door.
