## 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 strale-kyb-essentials-belgium-32328c38 -d '<json body>'
```

Example prompt: Can you pull the official KYB details for Belgian company with enterprise number 0123456789 — I need to verify they're legitimately registered before we sign a contract with them.

## When to prefer this

Use this endpoint when you specifically need to verify or enrich data about a Belgian-registered company using its enterprise number. It is ideal for KYB compliance workflows, supplier onboarding, or due diligence on Belgian entities. Prefer it over generic web search when you need structured, authoritative, audit-trailed company data directly from official Belgian sources.

- Unknown or deregistered enterprise number returns no data found
- Malformed request body returns 400 error
- Payment failure via x402 returns 402 Payment Required
- Service unavailability returns 503 with retry guidance
