## 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 uk-company-dossier-api-294bbfe5
```

Example prompt: Can you pull the full Companies House dossier for company number 00445790 — I need to know if they're active, who the current directors are, whether there are any overdue accounts, and if there's any insolvency history?

## When to prefer this

Choose this endpoint when you need a structured, enriched dossier of a UK company from the official Companies House register without requiring API key signup — ideal for AI agents needing on-demand due diligence or compliance checks paid per-call. Prefer this over scraping Companies House directly or using business data aggregators that require account setup, especially when you have a specific Companies House number and need risk flags pre-computed (officer churn, overdue accounts, insolvency history) in a single call.

## Known failure modes

- Invalid or non-existent Companies House number returns an error or empty result
- Malformed company number format (e.g. wrong length) may cause a 400 bad request
- Payment failure via x402 protocol blocks access to data
- Rate limiting or availability issues on the upstream Companies House API may cause delays or failures
- Very newly incorporated companies may have minimal filing or officer data

## How this service works

Pay-per-call UK company, property and crypto market data for AI agents via x402. Official sources, no signup, no API keys, failed calls never charged.

## Output

A JSON object containing the company's registered name, Companies House number, status (e.g. active/dissolved), incorporation date, current and past officers with roles and appointment dates, recent filing history with categories and descriptions, outstanding charges, gazette insolvency notices, and a flags summary including active officer count, accounts overdue status, company age, officer churn rate over 24 months, and insolvency history indicator.
