  KOMOJU has no subscription tiers, monthly fees, or setup fees for API access -
  its own marketing states "No sign up fees. No monthly fees. Ever!" Instead,
  KOMOJU charges a per-transaction fee that varies by payment method and region.
  Merchants open an account (test and live key pairs are issued) and are billed
  as a percentage of each successful transaction. High-volume merchants
  (published threshold around USD 150,000/month) can negotiate custom volume
  pricing. The rates below are Japan-region published rates and are indicative;
  exact contracted rates depend on the merchant agreement and are not reconciled
  here.
notes: >-
  Per-transaction rates are the effective "plan" for a payment gateway like
  KOMOJU. Rates are method- and region-specific and change over time; verify
  current pricing on en.komoju.com/pricing during reconciliation. The API itself
  carries no separate access fee.
