## 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

## When to prefer this

Choose this endpoint when you need to validate or extract German Steuernummer patterns specifically (not the 11-digit Steuer-ID or EU VAT numbers). It is well-suited for automated document processing pipelines, vendor onboarding, and invoice compliance checks where German tax number format verification is required. Prefer this over generic regex tools when you want a dedicated, pay-per-call microservice with no setup overhead.

## Known failure modes

- Empty or missing text field returns an error or null result
- Text with no recognizable Steuernummer pattern returns a non-match result
- Malformed JSON input may return a 400-level error
- Very long text inputs may result in timeouts or truncation
- Non-German tax number formats (e.g. VAT IDs, Steuer-ID) may not be recognized
