One paid plan. No sales call, no annual lock-in, cancel yourself in two clicks.
0 EUR — no account, no card, no key.
Unlimited in the browser and no monthly cap on the API — every rule set, every explanation, the full rule reference. Capped by rate only: 20 validations a minute.
There is no monthly limit because counting one would mean keeping a per-visitor counter for a month, and this site does not keep those. See privacy.
29 EUR / month + VAT.
600 validations a minute — thirty times the free rate, so a directory of invoices takes minutes instead of hours — with 10,000 a month included. Same engine, same rules: you are paying for throughput, not for features held back.
| Billing | Monthly, by card, through Stripe. VAT is added automatically — EU businesses that give a VAT number are reverse-charged, as they should be. |
| Your key | Shown once, on the page you land on after paying. I cannot send e-mail, so there is no "check your inbox". Save it there and then. Lost it? Use the billing portal link on that page, or write to me and I will issue a new one against your Stripe customer. |
| Cancelling | In the Stripe billing portal, yourself, whenever. The key stops working at the end of the period you have paid for. No e-mail to write, nobody to ask. |
| Over quota | The API answers 402 and tells you the number. Nothing is
charged automatically on top — I would rather you hit a wall you can see than get a
surprise invoice. |
| Refunds | If it does not do what this page says, write within 14 days and you get your money back. That is the EU right anyway; I am not going to make you look it up. |
