## 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`):

```

Example prompt: Can you look up the official Slovak company registration details for IČO 35763469 — I need the legal name, status, incorporation date, and registered office address from the RPO?

## When to prefer this

Use this endpoint when you need authoritative, live Slovak company data directly from the official government RPO register. Prefer this over web scraping or third-party databases when legal accuracy, freshness, and official sourcing are required — for example, KYB checks, invoice validation, supplier verification, or compliance workflows targeting Slovak entities. The CC-BY 4.0 license makes the data safe to store and redistribute.

## Known failure modes

- Invalid or non-existent IČO returns a not-found error
- IČO not exactly 8 digits returns a validation error
- Company exists in register but has no address on record — field may be null
- Network or upstream RPO availability issues causing timeouts
- Payment failure (x402) if USDC balance is insufficient
