The terms state

> Alternatively, for larger contracts, You may request to be billed via invoice.

> By providing payment information, You authorize us to charge Your credit card for usage fees or, in the case of invoice-based contracts, agree to make timely payments as specified in the invoicing terms.

And at the top there's a Try For Free button that says no credit card is required. This strongly communicates that this free trial won't incur any costs until you add a card or agree to be billed via invoice.

A simple change of the text would make people a lot less surprised. Warn them that if they go over they will be billed. In the bill clarify at the top that they don't actually have to pay if they don't want to.

Agreed - we've made this copy change to the free usage email now, and the change to add a toggle for preventing runs when you run out of credits is going through CI.
