## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call German PLZ validation check, especially in workflows where address data quality matters and you want a dedicated validator rather than a generic regex check. Best suited for single-call validation within agent pipelines handling German addresses.

## Known failure modes

- Invalid or malformed input text returns an error or failed status
- Non-German postal code formats (e.g. US ZIP, UK postcode) may not validate correctly
- Empty string input may return an error response
- Network or payment authorization failure (HTTP 402) if USDC payment is not included
