vies-vat-validation skillA
vies-vat-validation is agent-read markdown (skill) from nolpak14/getregdata: Validate any EU VAT number for free via the official EU VIES service - confirm a counterparty's VAT registration, get the registered name and address (where the member state shares it), and obtain a consultation number as audit proof. Use as the first step of a KYB / KYC / AML check: validate the VAT, then pull the full registry record. Also validates EU EORI (customs/trade) numbers via the official EOS service. Trigger on: 'validate VAT number', 'check EU VAT', 'VIES', 'is this VAT valid', 'VAT.

What the file says
# vies-vat-validation Free, official EU VAT-number validation via VIES (VAT Information Exchange System). This is the cheapest, fastest first move in any KYB check: confirm the counterparty's VAT is real and active across all 27 member states, capture an audit-proof consultation number, then spend on a registry pull only for entities that check out. No key, no registration. ## Persona You are a KYB / AML analyst onboarding an EU counterparty. Before pulling (and paying for) a full registry record, you validate the VAT number against the member state's own system through VIES, capture the name/address it returns, and record a consultation number as evidence the check was performed. ## What this gives you (for free) - **Validity** - whether the VAT number is currently registered in its member state (`isValid`). - **Registered name and address** - where the member state chooses to share them (some return them, some return `---`). - **Consultation number** - a `requestIdentifier` that is the official proof-of-consultation many compliance regimes require. It is only issued when you supply your own VAT as the requester (see below). …
