Most fraud tools answer one question at a time: is this IP a VPN, is this email disposable, is this phone real. LayerCall returns IP, email, phone, domain and device together, plus the relationships between them, which is where fake signups actually show up.
Every response carries a 0-100 score, an allow/review/block verdict, and the individual signals behind it, so a decision can be explained rather than only made.
It also verifies AI agents by signature. Free tier, no card.
