Less integration and maintenance work
Running your own BZSt integration means a BZSt access request, client maintenance, outage handling, and your own caching. Giltiq operates those parts and provides one REST endpoint with source and cache metadata.
Frequently asked questions
Sign up with an API key; email is optional. You get 100 VAT validations per month, structured JSON results with source and cache metadata, and usage headers on validation results.
Yes. By default, 10 API calls require no authentication at all. Just hit the endpoint directly: no signup, no API key, no email.
Every plan has a hard monthly cap. After that, requests return HTTP 402 until the next month begins. There are no automatic extra charges.
Yes. Monthly plans can be cancelled at any time; you keep access until the end of your current billing period. Annual plans can also be cancelled, but are non-refundable for the remaining term.
A VIES lookup tells you whether a VAT number is currently valid. A BZSt qualified confirmation under §18e UStG additionally submits the company name and address and returns the BZSt match results.
Annual plans are billed once per year at a 20% discount. Starter annual is €276/year (instead of €348). Business annual is €948/year (instead of €1,188).
Giltiq runs on Hetzner infrastructure in Germany. For validation, requests are forwarded to VIES or BZSt. See the privacy policy for details on data processing.
Yes. Giltiq runs an MCP server and publishes an agents.json capability declaration, an llms.txt, and an Agent Card.
If all reachable sources are unavailable and no stored result exists, the API returns SOURCE_UNAVAILABLE (HTTP 503). Such calls are not counted against your quota, up to 3 retries per VAT ID and hour.
BZSt qualified confirmations (§18e UStG) are currently part of the Business plan.
