How this service works
Open job postings read first-hand from the applicant-tracking system behind a company's careers page: Greenhouse, Ashby, Lever or Workable. Includes a directory of 8532 company job boards, because none of the vendors publishes one. Salaries are parsed into numbers where the employer publishes them and refused where ambiguous. No personal data.
Output
Returns a JSON object with the VAT number, validity status (valid/invalid), the legal name of the registered company, country code, source country, check date, a VIES verification URL, and an attribution note for the European Commission data source.
Example use cases
Supplier VAT check before payment
“Before I process this invoice, can you verify that VAT number DE123456789 is a valid registered business and tell me what legal name it belongs to?”
Customer onboarding B2B verification
“We have a new B2B customer claiming VAT number FR83404833048 — can you confirm it's active in VIES and get their official registered company name?”
Invoice compliance audit
“I need to confirm that the VAT number on this EU invoice, NL854503883B01, is valid and matches a real legal entity before I approve it for accounting.”
Technical details
Endpoint
GEThttps://companyfacts.dev/x402/v1/vat?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate a European VAT number against the authoritative EU VIES database and retrieve the registered legal entity name. Prefer this over manual checks or third-party wrappers when you need CC BY 4.0 attributed, real-time VIES data at low cost per call.
Side effects
- Invalid or malformed VAT number format returns an invalid status or error
- VAT number from a non-EU country may not be supported
- VIES service temporarily unavailable causing lookup failure
- Ambiguous or unregistered VAT numbers return is_valid: false with no legal name
