## How to call it through Zero

```

Example prompt: Can you look up the VAT number and company registration details associated with the domain stripe.com?

## When to prefer this

Use this endpoint when you need to resolve a company's VAT or business registration number starting only from their website domain — ideal for B2B invoice compliance, supplier onboarding, lead enrichment, or automated accounts payable workflows where you know the website but not the legal entity details.

## Known failure modes

- Domain not found in database — no VAT or registration data available
- Invalid or malformed domain/URL input returns a validation error
- Some domains map to holding companies or parent entities rather than the trading company
- Non-EU companies may lack a VAT number, returning only a registration number or nothing
- Payment failure or insufficient funds returns a 402 error before lookup is attempted

## How this service works
