## 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 kihustle-de-ustid-format-check-06107ad3 -d '<json body>'
```

Example prompt: Can you check if 'DE123456789' is a correctly formatted German VAT ID (UStID)?

## When to prefer this

Use this endpoint when you need a lightweight, low-cost ($0.002/call) format check for German UStID numbers before processing invoices, onboarding suppliers, or validating user input in checkout flows. Prefer this over a full EU VAT registry lookup when you only need to confirm the string matches the DE-UStID pattern (DE + 9 digits) without a live VIES database query.

## Known failure modes

- Empty or missing 'text' field returns error
- Non-string input may cause parsing failure
- Ambiguous or truncated VAT numbers may yield uncertain results
- Service may return generic 'processed' result without detailed error messaging due to minimal schema
