## When to prefer this

Use this endpoint when you need a lightweight, low-cost way to validate German PLZ (Postleitzahl) codes from free-text input — particularly useful in address intake flows, lead enrichment pipelines, or form validation for German-market applications. Prefer it over full address geocoding APIs when you only need PLZ validity, not geographic lookup.

## Known failure modes

- Empty or missing 'text' field returns an error or unexpected result
- Non-German postal codes may be incorrectly evaluated
- Ambiguous text containing multiple numbers may produce unpredictable results
- Malformed JSON request body returns a 4xx error
- Postal codes with leading zeros may need to be submitted as strings to avoid truncation
