How this service works
x402-Werkzeuge für autonome Agenten.
Output
Returns a structured JSON object containing the resolved company's legal name, email, phone, VAT ID, formatted address, country, legal form, register court, managing directors, and registration numbers. Also includes a confidence score (0–1), a list of sources consulted (e.g. vat_format, VIES, Impressum), any detected conflicts between sources, and field-level provenance showing which source contributed each value and with what confidence. A disclaimer note clarifies this is a synthesis of open sources, not an official registry excerpt.
Example use cases
Pre-contract vendor due diligence
“Before we sign with this supplier, can you look up 'Musterfirma GmbH' using their VAT ID DE123456789 and domain musterfirma.de and tell me their registered address, court of registration, and managing directors?”
Invoice VAT ID verification
“I got an invoice from a company claiming VAT ID DE298765432 and calling themselves 'Beispiel GmbH' — can you verify that ID is valid and matches that company name?”
Enrich CRM with official business data
“I have a lead called 'Alpha Services' with domain alphaservices.de — can you pull their full legal entity details including legal form, address, and contact info so I can update our CRM?”
Technical details
Endpoint
POSThttps://tools.netzhandwerker.de/v1/business/resolveWhen to prefer
Choose this endpoint when you need to resolve or enrich German business entity data using publicly available open sources such as VIES, VAT registries, and website Impressum pages. It is ideal for pre-contract due diligence, invoice verification, CRM enrichment, or any workflow requiring structured legal entity data for German companies. It is not a substitute for an official Handelsregisterauszug or a credit rating, but excels at fast, automated resolution combining multiple open signals into a single structured response with confidence scoring and provenance.
Side effects
- VAT ID not found in VIES — returns source ok:false for vies with no resolved data
- Domain has no accessible Impressum page — impressum source fails, reducing confidence
- Conflicting data across sources — conflicts array populated, confidence score lowered
- Malformed VAT ID format — vat_format source returns ok:false
- Insufficient input provided — if no name, domain, VAT ID, or registration number given, resolution may return empty or low-confidence result
- Network timeout reaching external sources — partial results with failed source entries
