## Where Things Live

## Plans and Checkout

Compare plans on the pricing page, then check out to change subscription or
top up balance. PATs with the Billing scope can read plans, balance,
invoices, and usage, and perform checkout, top-ups, and subscription
changes (see [Developer Scopes](/developer/scopes)).

## AI Usage

AI workflow generation is metered as a **monthly dollar budget**: Free $2, Pro
$5, and Elite $10. Usage is computed from the tokens each generation consumes.
A rolling 5-hour cap (20% of the monthly budget) and a rolling weekly cap (50%)
prevent a burst from draining the month.

**Plans & usage** shows the 5-hour, weekly, and monthly windows, how much of
each is used, and when capacity returns. When the included budget is exhausted,
generation stops until capacity returns. If **Bill overage to balance** is
enabled, generation continues from the prepaid balance instead.

AI usage paid from the balance is itemized on the next subscription invoice as
an **AI usage** line marked as paid from the balance, so it is never charged
twice. The usage breakdown also includes AI token and cost meters.
