Price covers up to 4096 output tokens at this model's own per-token price (see GET /v1/models), converted at $0.2273 per million credits. Minimum charge $0.01 per paid call. Unused tokens are not refunded in v1: the difference is credited to your paying wallet address on the topup ledger, to spend on another paid request.
