Example use cases
Invoice validation before sending
“Before I send this invoice to my German client, can you check that their VAT number DE298184782 is in the right format for a German USt-ID?”
Freelancer onboarding form check
“I'm building an onboarding form and need to validate that the USt-ID a new German business partner entered — DE123456789 — actually follows the correct German VAT ID format.”
B2B e-commerce tax compliance
“A customer filled in 'DE 987654321' as their German VAT number in our checkout — can you verify if that string is formatted correctly as a German USt-ID?”
Technical details
Endpoint
POSThttps://kihustle.tech/agents/api/v1/de-ustid-format-checkWhen to prefer
Use this endpoint when you need a quick, cheap programmatic check on whether a string is formatted like a valid German VAT ID (USt-ID), particularly in invoice processing pipelines, B2B onboarding forms, or EU tax compliance workflows targeting German businesses. Prefer this over manual regex checks or full EU VIES validation when only format (not existence) checking is needed and cost-per-call matters.
Side effects
- Empty or missing text field returns error or unexpected result
- Non-string input may cause processing failure
- Malformed JSON request body rejected
- Rate limiting or payment issues if USDC micropayment fails
- Ambiguous result schema makes it unclear if format is valid or just received
