## 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 sirenic-latvian-ubo-beneficial-owners-lookup-e449bbba
```

Example prompt: Who are the registered beneficial owners of the Latvian company with registration number 40003229495? I need their names, nationalities, and countries of residence from the official Latvian register.

## When to prefer this

Use this endpoint when you need official, government-sourced UBO data for a Latvian-registered entity. It draws directly from Latvia's national open-data register (CC0 licensed, refreshed daily), making it more authoritative and more detailed than self-reported or commercially aggregated sources. Prefer it over general European company lookup tools when the target is specifically a Latvian entity and you need UBO-level granularity including nationality and country of residence.

## Known failure modes

- 404 returned if the 11-digit registration number does not exist in the register
- Empty list returned when no UBOs are registered — this does not mean the company has no beneficial owners
- GDPR minimisation means the Latvian personal identity number is never exposed; only birth month+year when officially published
- Daily refresh cadence means very recently changed UBOs may not yet be reflected
- Malformed or non-11-digit registration numbers will fail input validation

## How this service works

Latvian beneficial owners (patiesie labuma guvēji) from the official Uzņēmumu reģistrs open data (CC0, refreshed daily), for AML, KYB and compliance ownership checks: registered UBOs in Latvia with name, nationality, country of residence and registration date — an open national UBO register, depth France does not expose. GDPR minimisation: never the Latvian personal identity number, birth month+year only when published. 11-digit registration number.

## Output

A list of beneficial owner records for the specified Latvian company, each containing the owner's full name, nationality, country of residence, and registration date. Birth month and year are included only when published by the register. An empty list indicates no UBOs are registered (not necessarily that no beneficial owners exist, as non-registration cases are permitted under Latvian law). Returns 404 if the registration number is unknown.
