Prepaid subscription
You pay a fixed price per cycle. There is no wallet to keep topped up and no per-token invoice — the plan price is the price.
Daily + weekly billed-usage limits
Both limits apply. When either window is used up, calls pause until that window resets automatically. The USD figure is metered API usage, not cash balance and not a fixed number of calls.
Official-ratio quota metering
Sol is the 1.00× baseline. GPT-5.5 uses 1.00×, GPT-5.4 uses 0.50×, Terra uses 0.40×, and Luna uses 0.04×. The same rates apply on Lite, Standard, and Pro.
Upgrade amount versus quota
An upgrade checkout amount can be lower than the plan price because unused time on the current plan is credited. That amount is the payment due now; it is not the daily or weekly usage limit.
Enterprise route
High-volume teams move to enterprise pricing with dedicated channels, invoicing, and controlled model access.
