summary: >-
  Pure usage-based prepaid pricing — no subscription tiers, no free trial, no monthly plans. Credits
  are purchased up front (guest checkout, no signup required for agents) and drawn down per request.
  There are no named plan tiers, so plan_count is 0; the priced surface is the per-model token rate.

  note: >-
    Successful API requests are billed at the displayed token rates, metered to a fraction of a cent.
    Charges accumulate and are deducted from your prepaid balance in whole US cents, so a small request is
    not rounded up to a minimum charge. A prepaid credit purchase is a balance purchase, not a per-request price.

    US$0.01 per-request minimum and per-request rounding rule
