How it works
How billing works
Billing is prepaid and transparent. You fund a balance, and each request draws down official spend minus your discount, with a full breakdown you can audit.
·
Prepaid balance
You top up any whole-dollar amount. Balance never expires and there is no subscription, so idle time costs nothing.

Per-request metering
- Each call is converted to official Anthropic spend by token.
- Your active discount (60% up to 80% for B2C) is subtracted.
- The net amount is deducted from your prepaid balance.
Full visibility
Every request appears in your dashboard with input, output, cache and thinking tokens, so you always know where your balance goes.
Frequently asked questions
Is billing prepaid or postpaid?
Prepaid. You fund a balance in advance and requests draw it down; there is no monthly invoice.
Can I see token-level usage?
Yes. The dashboard breaks every request down by input, output, cache read/write and thinking tokens.
