Output Fields

Identifier Rules

ust_id is normalized to DE plus nine digits and must match ^DE\\d{9}$.
Invalid VAT-like values return ust_id: null and include invalid_vat_id in _registry_meta.warnings.
steuernummer preserves the tax number format as listed in the imprint.
Extraction is regex-first over the imprint extraction result. No additional OpenRouter request is made by this endpoint.

Outbound website fetches are delegated to imprint_extractor, which uses the shared SafeUrlValidator. This endpoint does not implement a separate crawler.
