## 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 getapi-kvk-number-validation-c338f0f1 -d '<json body>'
```

Example prompt: Can you validate KVK number 59581883 and tell me if the company is currently active and registered in the Netherlands?

## When to prefer this

Use this endpoint when you need to verify Dutch business registrations specifically via KVK number. It is purpose-built for the Netherlands Chamber of Commerce registry and returns structured business metadata including legal form, insolvency status, and SBI activity codes — making it superior to generic company lookup APIs for Dutch B2B due diligence, supplier onboarding, invoice validation, or compliance workflows.

## Known failure modes

- KVK number not found in registry — found: false, valid: false
- KVK number format invalid — error returned
- Company exists but is no longer active — actief: false
- Rate limiting — retry_after field populated
- Network or upstream registry unavailability
