Example use cases
Onboarding B2B customer VAT validation
“Before we create this German business account, can you verify that 'DE987654321' is a properly formatted German USt-IdNr?”
Invoice data quality check
“I'm about to send an invoice with the VAT ID 'DE 123 456 789' — can you check if the format is correct for a German Umsatzsteuer-Identifikationsnummer?”
Bulk-imported supplier record cleanup
“We imported this supplier record and the VAT field contains 'DE12345678' — does that match the official German USt-IdNr format?”
Technical details
Endpoint
POSThttps://kihustle.tech/nexus/api/v1/de-ustid-format-checkWhen to prefer
Use this endpoint when you specifically need to check whether a string conforms to the German USt-IdNr (DE VAT ID) format as a lightweight, low-cost pre-validation step before submitting to official VIES or Bundeszentralamt für Steuern verification services. It is not a live registry lookup — it only checks the format pattern.
Side effects
- Missing or empty 'text' field returns an error or ambiguous result
- Non-string input may cause a processing error
- Network timeout on the kihustle.tech host
- Ambiguous response schema — 'processed'/'success' may not distinguish format-valid vs format-invalid cases clearly
