Do we pre-pay for API tokens, or do they bill us after the fact?
If the latter, can we switch to prepaying? I have paranoia of something going wrong and using up too many tokens and going into debt. I would rather be limited by prepaid amounts.
Post-paid.
You basically get an allowed limit each month and you pay for what you use.
You can set both a soft limit and hard limit. Soft limit means it gives you a warning. Hard limit means it cuts off access past a certain point.
