Commercial safety
The billing layer should feel boring in the best possible way.
Usage checked before requests run
The product should look at allowance first so expensive model calls do not sneak through after the budget is gone.
Plan state tied to real purchases
A customer should not appear to have a paid plan unless checkout and entitlement state actually say they do.
Top-ups instead of surprise charges
Extra usage can be explicit, visible, and opt-in instead of turning into vague background billing.
Built-in protection
Usage should be enforced on the server, not trusted to the UI.
Stronger models use credits faster. ClastX should check the remaining allowance before requests run, then offer a top-up, an upgrade, or a pause point before anything expensive slips through.
