## When to prefer this

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.

## Known failure modes

- 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

## How this service works
