## 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 factstamp-entity-file-d468572c -d '<json body>'
```

Example prompt: Pull the full entity file for Acme Holdings Ltd — I need their registered office, SIC codes, filing position, a sanctions check across all five lists, and whoever's listed as a person with significant control before we sign the contract tomorrow.

## When to prefer this

Choose this endpoint when you need a consolidated due diligence report on a legal entity at the moment of a transaction, onboarding, or acquisition — replacing four or more separate calls to company registries, sanctions APIs, and ownership databases. Ideal for KYB workflows, compliance automation, and pre-signing counterparty checks where breadth of coverage (identity + sanctions + ownership in one receipt) matters more than deep narrative analysis.

## Known failure modes

- Company not found in any covered register — returns empty or not-found response
- Jurisdiction not covered — endpoint may return partial data or an error indicating unsupported territory
- Sanctions list provider outage — one or more of the five screens may be unavailable
- Invalid or malformed company identifier — returns validation error
- LEI not registered for the entity — ownership/parent data absent from response

## How this service works

One company in full at the point of signing, onboarding, paying or acquiring — a company check by company number or name across the company registers. Identity and standing, registered office, SIC and prior names, the filing position, a sanctions screen across six lists, plus the ownership the registers publish (persons with significant control where published; parent relationships where a company has an LEI; beneficial ownership not public in nearly every country we cover). Not a KYB provider.

## Output

A single JSON object containing the company's full identity and standing (name, registration number, jurisdiction, status), registered office address, SIC and previous names, current filing position, sanctions screening results across five lists, persons with significant control (where published by the register), LEI-declared parent relationships, and a note on beneficial ownership availability.
