## 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`):

## When to prefer this

Choose this endpoint when you need a lightweight, inexpensive per-call validation of German Steuernummer patterns in free text or structured strings. Prefer it for invoice processing pipelines, German business onboarding flows, or document compliance checks where detecting or verifying the German tax number format is the specific goal, rather than a general tax ID validator covering multiple countries.

## Known failure modes

- Empty or missing text field returns an error or unprocessable result
- Text with no German tax number pattern returns a non-match result
- Malformed request body causes a 400 error
- Rate limiting or payment failure returns a 402 response
