# Pricing and limits

> Prepaid USD billing, token rates, and default account controls.

## Token rates

* aster-work: $0.40 per million input tokens and $0.80 per million output tokens.
* aster-code: $0.80 per million input tokens and $1.60 per million output tokens.
* Input and output are metered separately. Pricing is versioned so later changes do not rewrite settled usage.

## Prepaid balance

* Checkout shortcuts are $5, $10, $25, $50, and $100, with custom purchases from $5 to \$1,000 USD.
* Balance does not expire. There is no subscription, seat fee, customer auto-top-up, or wallet reserve in the MVP.
* Failed and cancelled requests are not charged. Successful usage settles from the prepaid balance.

## Default controls

* New accounts start with a configurable \$1,000 UTC daily spend limit.
* An account may have up to 10 active API keys and 10 concurrent pending requests by default.
* Limits are operating controls and can change; the app shows the values that apply to your account.
