FAQ
Frequently asked questions
What is Stawka?
Stawka is a REST API for European tax data. It returns up-to-date VAT rates for all 27 EU member states, the European Central Bank's daily euro reference exchange rates, and real-time VIES VAT-number validation — all as clean JSON over simple authenticated GET requests.
Where does the data come from?
VAT rates are aggregated from the European Commission's Taxes in Europe Database (TEDB), FX rates come straight from the European Central Bank, and VAT-number checks query the EU's official VIES service in real time. We normalise these primary sources into one consistent schema.
How current are the VAT rates?
Rates are tracked continuously and updated whenever a member state changes one. You can query the latest rates, fetch the exact rates in force on any past date, read a change log, or subscribe to a signed webhook that fires the moment a rate moves.
Do you have a free plan?
Yes. The free tier needs no credit card and lets you start making calls immediately. Paid tiers raise the per-minute and monthly request limits and unlock webhooks. You can cancel any time.
How do I authenticate?
Sign up, create an organization, and mint an API key. Send it as a Bearer token in the Authorization header of each request. No SDK is required — anything that speaks HTTP works.
Can I validate EU VAT numbers?
Yes. GET /vies/{country}/{vat} checks any EU VAT number against the official VIES system in real time and returns whether it is valid, plus the registered business name and address when the member state makes them available.
