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: is_valid (boolean), legal_name (company name as registered), vat_number (normalized), country_code, check_status ('valid' or other), checked_date (ISO date), verify_url (VIES link), source ('vies'), source_country, and attribution noting CC BY 4.0 licensing. Returns null for check_note when no issues are found.
Example use cases
Supplier onboarding VAT check
“Before we add this new supplier to our system, can you verify their EU VAT number DE811762532 and confirm the legal business name it belongs to?”
Invoice compliance validation
“I need to check whether VAT number FR12345678901 is actually registered and valid before I accept this invoice — can you look it up and tell me the company name?”
Customer VAT reverse-charge eligibility
“A customer gave us VAT number PL5213016docile — wait, their number is PL5213016000 — can you validate it against the EU VIES system so I know if we should zero-rate their invoice?”
Technical details
Endpoint
GEThttps://ats-jobs-api.groundtruthtools.workers.dev/x402/v1/vat?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate EU VAT numbers directly against the authoritative VIES system, particularly when you need the registered legal name alongside validity status. Prefer this over generic tax APIs when you need CC BY 4.0 attributed EU-official data, structured numeric output, and a direct VIES verification link for audit trails.
Side effects
- Invalid VAT format returns is_valid: false or an error
- VAT number not found in VIES returns is_valid: false
- VIES service temporarily unavailable causes upstream timeout
- Malformed VAT string (missing country prefix) may cause parsing error
- Some member states restrict real-time VIES lookups causing inconclusive results
