How this service works

Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.

Output

Returns a JSON object containing the queried VAT number, a boolean validity flag, the registered company name, the registered address, the timestamp of the check, and a note about the data source (European Commission VIES). The response is informational and not a substitute for official tax confirmation.

Example use cases

Supplier VAT verification before payment

“Before I pay this invoice, can you verify that the VAT number NL854657700B01 is a real registered business in the EU and tell me what company name is on file?”

B2B invoice compliance check

“I'm about to issue a zero-rated B2B invoice to a German company. Can you validate their VAT number DE811193041 and confirm the registered name matches 'Volkswagen AG'?”

Customer onboarding VAT validation

“A new customer signed up and gave us VAT number FR40303265045 — can you verify it's valid and pull the official company name and address registered with EU VIES?”

Technical details

Endpoint

GEThttps://api.ambolt.dev/v1/eu-vat-validate?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a quick, pay-per-call EU VAT number validation without managing your own VIES API integration. Ideal for agents handling supplier onboarding, invoice compliance, or B2B customer verification where you need the registered company name and address alongside the validity check. Prefer this over building a direct VIES integration when you want zero infrastructure overhead and per-call pricing.

Side effects

Invalid or malformed VAT number returns valid=false
VAT number not found in VIES returns valid=false with no name/address
VIES system temporarily unavailable (EU service outages are known to occur) may return an error
Unsupported country prefix returns an error
VAT number exceeds 20 characters after stripping spaces/dots returns validation error
