## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability latvian-vat-pvn-number-validator-a914e3f1 -d '<json body>'
```

Example prompt: Can you check if the Latvian VAT number LV40003009497 is currently active and registered in the official VAT payers register?

## When to prefer this

Use this endpoint when you specifically need to verify a Latvian (LV-prefix) VAT/PVN number against the official State Revenue Service register. It is the authoritative source for Latvian VAT registration status. Prefer it over generic EU VAT validators when dealing with Latvian counterparties, as it queries the live national register directly. For other EU countries, use the sibling endpoints (Poland, Norway, France, Czech Republic, Finland).

## Known failure modes

- Invalid format — number not matching 'LV' + 11-digit pattern returns a validation error
- Number not found in the register — valid format but no active entry exists
- Data source unavailability — data.gov.lv register may be temporarily unreachable
- Input too short or too long — minLength 11, maxLength 20 enforced on vatNumber field
- Network or payment failure — x402 payment not processed correctly

## How this service works

Validate a Latvian VAT (PVN) number against the official VAT-payers register. Validity means the number has a currently active entry in the register.

## Output

Returns whether the submitted Latvian VAT/PVN number has a currently active entry in the State Revenue Service VAT-payers register, indicating the entity is a registered VAT payer in Latvia.
