Questions about the plan
Do I need an account?
No. The free tier has no account at all. The Pro plan issues a license key after the payment, and the key is what raises the limits. It lives in your browser, not on a server that holds your details.
Who handles the payment?
Dodo Payments acts as the merchant of record. They take the payment, calculate the tax where it applies and issue the invoice in your name.
Can I cancel?
Yes, from the customer portal that the receipt links to. The plan stays active until the end of the period you paid for.
Is anything held back from the free tier?
No. Every check, every tool, the reports, the API and monitoring work without paying. Pro is about volume: more audits an hour, deeper audits, more and more frequent monitors, longer retention.
How do I use the key with the API?
Send it in the X-Aback-Pro-Key header, or add it on the dashboard so the website sends it for you. A key that is not active is ignored and the request runs with the free limits.
