description: Arbital Health is a healthcare technology and actuarial-services company building the neutral third-party infrastructure
  for adjudicating outcomes-based (value-based care) contracts between payers, providers, employers, risk-bearing entities
  and point-solution vendors. Its cloud platform centralizes risk contracts, ingests and validates claims and eligibility
  data, runs actuarial calculations (IBNR, MLR, benchmarks, attribution), predicts and monitors contract performance, and
  adjudicates settlement between the parties. Product lines include the Adjudication Platform, ATLAS, Merlin AI, and Arbital
  Flex — a self-serve actuarial AI tool for payors and providers — alongside a traditional actuarial consulting practice built
  on the acquired Santa Barbara Actuaries team. The company launched in 2024, raised a $10M Series A led by Transformation
  Capital, and holds SOC 2 Type 2 and HITRUST i1 certification.

  detail: Arbital Health runs a real JSON API at platform.arbitalhealth.com/api — /api/health answers 200 — but every resource
    path, including /api/openapi.json, returns 401 {"error":"Unauthorized"} to an anonymous caller, and no developer portal,
    API reference or spec exists anywhere on the marketing site (arbitalhealth.com is a 13-page HubSpot CMS site with no /docs,
    /developers or /api route).
