FAQ
Frequently Asked Questions
What happens if I exceed my Free tier request limit?
Your API calls will return a 429 Too Many Requests response until the next calendar month. We'll email you a heads-up at 80 % usage so you can decide whether to upgrade.
Can I switch plans mid-billing cycle?
Yes. Upgrades take effect immediately and you'll be prorated for the remainder of the month. Downgrades apply at the start of your next billing period so you don't lose access mid-cycle.
Is there a volume discount for large teams on Pro?
At 20+ seats, Pro drops to $15/month per seat. For 50+ seats, contact us — we typically offer a custom rate and can include a free onboarding workshop.
How does the Enterprise on-premise deployment work?
We provide a Docker-based JSONFlow appliance that you deploy inside your VPC or on bare metal. Our team handles the initial provisioning and gives you a runbook for ongoing maintenance. Licensing is annual, billed upfront.
Do you offer a free trial of Pro features?
Absolutely. Start a 14-day Pro trial with no credit card required. You get full access to unlimited requests, transformations, and team workspaces. When the trial ends, you can keep using the Free tier or subscribe.
