How billing works

Checkout, receipts and cancellation are handled by Whop. Use the same email as your AttestOS account and confirm it; the plan attaches within seconds of payment. Cancel any time in Whop → Memberships; you drop back to the free limits at the end of the period.

Over your monthly limit? Verifications keep working up to 10% over, then siteverify answers quota-exceeded, and the docs show how to fail open so sign-ups never stop.
