  Optum publishes no price, no tier, no per-transaction rate and no published quota for any API on
  developer.optum.com. The only self-serve path is a free sandbox request form on
  marketplace.optum.com — which the docs describe as testing "without financial obligation",
  implying but never stating that production is paid. Production access is negotiated through an
  Optum representative or an existing clearinghouse/revenue-cycle contract; the developer portal
  carries no pricing page, no calculator, and no "contact sales" pricing tier table. Recording
  plan_count: 0 is the finding, not a gap in the search: for a clearinghouse of this size, the
  per-transaction economics live entirely inside a commercial agreement.

    Canned-response sandbox only. No production data, no PHI/PII, load testing explicitly
    prohibited. Credentials are issued manually after a request form is reviewed.
