Vendor Risk & KYB Suite

Vendor Risk & KYB Suite — Assess business counterparties with one API: validate domains, verify business emails, validate VAT and EIN numbers, and classify connecting IPs for risk.

🏢 Validators + lookups

🚀 Newcomer launch pricing — limited-time introductory rates while we earn our first reviews.

Built for risk, procurement, and compliance teams, KYB and B2B-onboarding platforms.

Why this exists

Know-your-business checks — domain, email, VAT, EIN, IP — come from separate data vendors with no unified call.

What you get

One API key validates business domains, emails, and tax numbers and classifies IPs — the KYB risk-signal layer.
