API pricing and charges in Tokeniser
Balance units, final rates, minimum charge, reservations and tariff versions.
Funding and usage
A top-up credits balance units under the selected offer. Requests spend those units at the model tariff. Check the payable amount and credited units before payment.
Token components
Uncached input, cached input, regular output and reasoning have separate rates. Cached and reasoning tokens are not counted twice. The total is rounded up once and the displayed minimum charge is then applied.
Reservations and versions
Accepted requests retain their tariff version. An upper usage estimate is reserved, then the actual amount is charged and the remainder released. See the catalog for final rates and minimums.
Images and audio
Separately accepted modes can charge per image or audio second with specific allowed settings. Ordinary text-token rates do not describe those charges.
