Output

Example use cases
Invoice VAT verification for accounting
“Before I process this invoice, can you check if the VAT number DE345789123 on it is valid and confirm the company name and address associated with it?”
Supplier onboarding compliance check
“We're onboarding a new EU supplier who gave us VAT number FR12345678901 — can you verify it's a legitimate registered VAT number and pull their company details?”
Customer VAT validation for B2B sales
“A customer wants to buy without VAT and provided the number NL123456789B01 — can you validate that VAT number and tell me if it checks out and what business it belongs to?”
Technical details
Endpoint
GEThttps://x402.orthogonal.com/abstractapi/v1/validateWhen to prefer
Choose this endpoint when you need to verify a business's VAT registration status and retrieve associated company details in a single call, particularly for B2B invoice validation, supplier onboarding, or tax compliance workflows. Prefer this over generic business lookup endpoints when you specifically have a VAT number as the starting identifier.
Side effects
- Invalid or malformed VAT number format returns validation failure with no company data
- VAT number not found in registry returns invalid status
- Network or upstream registry timeout may cause intermittent failures
- Unsupported country prefix may result in inability to validate
- Empty or missing vat_number parameter returns an error
