How this service works
x402-Werkzeuge für autonome Agenten.
Output
Returns a JSON object with: a boolean 'valid' field, a 'completeness' percentage (0–100), a 'parsed' object with individual address components (street, house_number, city, postal_code, addition), a 'formatted' array of address lines, a 'formatted_single_line' string, the ISO 'country' code, 'country_name', plus 'issues' and 'hints' arrays for any detected problems, and a 'note' clarifying that this is a format check only, not a registry lookup.
Example use cases
Validate customer shipping address
“Before we ship this order, validate the customer's address: Berliner Str. 5b, 10115 Berlin, Deutschland — tell me if it's complete and correctly formatted.”
Parse free-text address into structured fields
“I have this address written on a single line: 'Musterweg 3, 80331 München, Germany' — can you parse it into separate fields like street, house number, postal code, and city?”
Check address completeness for a contact form
“A user filled in their address as 'Gartenstraße, Hamburg, DE' — is this address complete and valid, and what's missing?”
Technical details
Endpoint
POSThttps://tools.netzhandwerker.de/v1/address/validateWhen to prefer
Choose this endpoint when you need lightweight, fast address format validation and normalization without requiring a connection to an official address registry. It is ideal for pre-validating user input in forms, normalizing free-text addresses into structured components, or checking address completeness before storage — especially for German and European addresses. It is not suitable when you need to verify that a street actually exists (registry lookup) or when geocoding coordinates are required.
Side effects
- Unrecognizable address format — parser cannot split components, may return low completeness or issues
- Unsupported country — country code or name not recognized, validation may be incomplete
- Missing required fields — if neither 'address' nor individual fields are provided, validation cannot proceed
- Ambiguous street/house number split — may be parsed incorrectly if format is unusual
- Network or payment failure — x402 micropayment not processed, request rejected
