# Credits

Each mech has its own prepaid balance in USD. Runs spend the balance of the mech they run on: model tokens
at published rates, plus active sandbox time metered per second. Current rates are on the
[pricing page](https://mechane.ai/pricing).

## Adding credits

Workspace owners add credits at `mechane.ai/<workspace>/credits`: choose the mech, enter an amount, and pay
with Stripe Checkout. Credits appear once Stripe confirms the payment, usually within a minute. Credits do
not expire.

## While a run is active

A run reserves part of the balance while it works and settles what it used when it finishes. There is no
per-run dollar cap by default. Credits added during a run are available to the next run.

Automatic reload is not available in this beta.

The full terms are in the [credit terms](https://mechane.ai/terms).
