Get your API key.
Create an account and start generating synthetic JSON data in minutes. Pick a plan, add a payment method, and we’ll hand you an API key — 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 collected and sent directly to Stripe from your browser; JsonFabrica never sees or stores your card number.
