Output
Returns a JSON object indicating whether the input text contains a valid German Steuernummer pattern, with a result field (e.g. 'processed') and a status field (e.g. 'success'). May also include the extracted or matched tax number string.
Example use cases
Invoice tax number compliance check
“I have a German invoice with the text 'Steuernummer: 181/815/08152' — can you verify that the tax number in there follows the correct German Steuernummer format?”
Extract tax number from business document
“Pull out any German tax number (Steuernummer) you can find in this text: 'Unser Unternehmen, eingetragen unter der Steuernummer 4151081508150, freut sich auf die Zusammenarbeit.'”
Batch document onboarding validation
“We're onboarding a new German vendor and their registration doc says '22/815/08151' — does that match the official Steuernummer pattern so we can mark their profile as tax-verified?”
Technical details
Endpoint
POSThttps://kihustle.tech/nexus/api/v1/de-steuernummer-patternWhen to prefer
Choose this endpoint when you need to validate or extract German Steuernummer patterns specifically (not the 11-digit Steuer-ID or EU VAT numbers). It is well-suited for automated document processing pipelines, vendor onboarding, and invoice compliance checks where German tax number format verification is required. Prefer this over generic regex tools when you want a dedicated, pay-per-call microservice with no setup overhead.
Side effects
- Empty or missing text field returns an error or null result
- Text with no recognizable Steuernummer pattern returns a non-match result
- Malformed JSON input may return a 400-level error
- Very long text inputs may result in timeouts or truncation
- Non-German tax number formats (e.g. VAT IDs, Steuer-ID) may not be recognized
