Billing uses a single USD wallet per account. Balances and usage are shown in dollars (for example, $5.00).

Wallet buckets

The available balance is the sum of remaining grant balances. Monthly usage on the Usage page shows spend against your plan allowance for the current period (for example $0 / $5 used on Hobby).

What is metered

The wallet covers chat model usage and metered usage submitted through the Developer API. The product reserves an estimate before generation and charges the actual amount afterward.

Plan limits (requests per minute, sessions per day, allowed models) are entitlements, not separate wallet lines.

Grant order

When usage is debited, grants are consumed in this order:

1. Daily login
2. Monthly included
3. Purchased / top-up
4. Enterprise / custom (when configured)
