  Omise (Opn Payments) does not sell API access tiers. The API and dashboard are
  free to use; the company earns per-transaction processing fees (a percentage of
  each successful payment, varying by country and payment method), plus fees on
  some payouts and value-added services. Pricing is country-specific across
  Thailand, Japan, and Singapore and is quoted on the regional pricing pages;
  large or high-volume merchants can negotiate custom rates. Test mode is fully
  free. Per-transaction rates below are indicative and NOT reconciled - confirm
  on the current regional pricing page.
notes: >-
  There is no monthly API subscription or request-metered plan. Cost is a
  percentage of transaction value, so the "plans" here model the commercial
  engagement (self-serve standard rate vs. negotiated enterprise rate) rather
  than API quota tiers. Rates shown are Thailand indicative figures and exclude
  applicable VAT.
