What this is good for

A toolkit for compliance, KYC/AML, accounting and cross-border checks over Czech & EU registries:

• VAT & invoicing — verify VAT-payer status (ADIS) and convert at official ČNB FX rates before booking.
• Counterparty screening — ARES identity, EU + OFAC sanctions, ISIR insolvency.
• Due diligence (flagship) — the @czagents/dd aggregator combines the above into a risk score, statutory-chain / UBO walk, and EU-parent lookup.
• Cross-border — company lookups across GB / SK / PL / NL / DE / FR registries (@czagents/eu-registry).

Use a single-source server when you need just one dataset; use the due-diligence aggregator for combined, scored output.

Example prompts the aggregator handles well:

• KYC pre-invoice — "Before we send a 350 000 Kč invoice to IČO 11122234, flag any insolvency, sanctions, unreliable-VAT-payer status, or nominee-director red flags."
• Vendor onboarding — "Run KYC on this prospective supplier and tell me if anything looks off. Use the full statutory chain."
• M&A pre-due-diligence — "Generate a DD report on the acquisition target and walk the statutory body two levels deep — flag any insolvent firms in the network."

Score & validation
