How this service works
Verify French companies, EU VAT numbers, and addresses from one API. Pay per call with USDC on Base via x402. No account, no API key.
Output
A JSON object containing the submitted VAT number, a boolean validity flag, the registered company name, the full registered address, and the two-letter country code (e.g. FR).
Example use cases
Supplier onboarding VAT check
“Before I add this new French supplier to our system, can you verify their VAT number FR12345678901 and confirm the company name and address match what they gave us?”
Invoice compliance verification
“I need to validate the EU VAT number FR40303265045 on an invoice I received — is it legitimate and what company does it belong to?”
B2B lead enrichment
“I have a French company's VAT number, FR82494978100 — can you look up their registered business name and address so I can enrich my CRM record?”
Technical details
Endpoint
GEThttps://veriffr.vercel.app/api/v1/vat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate a French or EU VAT number and retrieve the associated company name and address in a single call, without needing an account or API key. It is ideal for ad-hoc compliance checks, supplier onboarding, or invoice validation workflows where pay-per-call USDC pricing is acceptable. Prefer alternatives if you need bulk VAT validation or non-EU tax ID verification.
Side effects
- Invalid or malformed VAT number returns valid: false with no company details
- VAT number without two-letter country prefix may cause a bad request error
- Non-EU or unsupported country prefix may return an error or invalid result
- Payment failure via x402/USDC may block the request entirely
- Rate limits or service downtime on the Vercel-hosted backend may cause 5xx errors
