Get your API key.

Create an account and start generating synthetic JSON data in minutes. Pick a plan and enter your email — we’ll redirect you to Stripe’s secure checkout to add a payment method. Once payment is confirmed, we’ll email you an API key (and show it once on the confirmation page) — no sales call required.

Starter starts with a 30-day free trial; Growth and Business are billed immediately at signup, with no trial. A payment method is required for every plan. On Starter, you will not be charged during the trial — your card is only charged automatically once the trial ends, unless you cancel first. Your card details are entered directly on Stripe’s hosted checkout page — JsonFabrica never sees or stores your card number.

30 days free, then your card is charged automatically.

Only Starter has a free trial. A valid card is required now, but you won’t be charged during the 30-day trial. If you don’t cancel first, your card on file is automatically charged Starter’s monthly rate when the trial ends on day 31.

You’ll enter your card on Stripe’s secure checkout page next.
