Common questions.

Do I need a credit card to start?

No. Sign up and your 14-day trial starts. No card required.

What happens to my docs after the trial?

Your docs stay up. You can't publish changes until you subscribe, but nothing is deleted.

Can I cancel anytime?

Yes. Cancel any time. You keep access until the end of your billing period.

How do I upload my API spec?

Drop a YAML or JSON file in the dashboard. Or use the npm package or REST API to automate uploads.

What is the difference between the trial and a Pro subscription?

None. The trial is full Pro for 14 days. After that, 35 EUR/month keeps everything running.
