How this service works
Deterministic lookups from official public sources (ARES, EU VIES, Czech National Bank, GLEIF LEI index). No AI, no scraping. Pay per call in USDC on Base via x402. Requests that fail upstream (5xx/timeout) or not-found results are not charged.
Output
Returns a JSON object with the company name, a boolean validity flag, the registered address, VAT number, country code, the official source (EU VIES), and the timestamp of the request. If the VAT number is not found or upstream fails, no charge is made.
Example use cases
B2B invoice VAT compliance check
“Before I issue this invoice, can you verify that my client's EU VAT number DE123456789 is currently registered and valid, and give me their official registered company name and address?”
Supplier due diligence verification
“I need to onboard a new Czech supplier who gave me VAT number CZ27074358 — can you look them up on VIES and confirm the company name and address match what they told me?”
Automated VAT validation at checkout
“A customer entered VAT number FR12345678901 to claim a B2B tax exemption on their order — can you verify it's valid on VIES and pull the registered business name so I can record it?”
Technical details
Endpoint
HEADhttps://x402.tuancodes.workers.dev/vies/%7Bvat%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, real-time EU VAT validation from the official VIES system with no AI inference or scraping involved. Ideal for B2B invoice compliance, supplier onboarding, and tax exemption verification where an official deterministic result is required. Particularly suited for Czech company lookups given the additional ARES data source. Prefer over generic company data APIs when you specifically need VAT validity confirmation rather than general business information.
Side effects
- VAT number not found in VIES — returns not-found result, no charge applied
- Upstream VIES service timeout or 5xx error — request not charged
- Malformed VAT number format — may result in upstream rejection
- Country code not supported by EU VIES — lookup fails
- Transient VIES availability issues during peak EU business hours
