## 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-german-tax-number-steuernummer-pattern-validator-e6b98719 -d '<json body>'
```

Example prompt: Can you check whether the text 'Steuernummer: 181/815/08155' contains a valid German tax number pattern?

## When to prefer this

Use this endpoint when you need to validate, detect, or extract German Steuernummer (state tax numbers) from free-form text — particularly in invoice processing, KYC workflows, or German business document automation. Prefer this over generic regex libraries when you need a managed, pay-per-call API that abstracts away regional format variations across German states.

## Known failure modes

- Empty or missing text input returns an error or null result
- Text with no detectable Steuernummer returns a non-match status
- Malformed JSON body causes a 400 error
- Rate limiting or payment failure returns a 402 error
- Ambiguous or partial tax numbers may be incorrectly matched or rejected
