Dutch supplier screening — pre-transaction check in one call: validates the EU VAT number (VIES), checks the official Dutch Central Insolvency Register for bankruptcy, suspension of payments or debt restructuring, and cross-checks the legal name against the VAT-registered name where available. Requires legal_name, kvk_number and vat_number. Returns factual attention items with a source reference per finding — no risk scores. Only charged when both registers were consulted. Companies only.
