description: 'Accelerant Holdings (NYSE: ARX) operates the Accelerant Risk Exchange,
  a data-driven marketplace that connects underwriters of specialty insurance risk
  — MGAs, program administrators, captive managers and retail brokers, referred to
  as Members — with risk capital providers including insurers, reinsurers and institutional
  investors. Founded in 2018 and headquartered in Grand Cayman with operations across
  the United States, Canada, the United Kingdom, Europe and Australia, the company
  runs three segments: Exchange Services, MGA Operations and Underwriting. Its member
  platform at app.accelerant.ai delivers AI and machine-learning underwriting products
  — risk scoring, portfolio risk monitoring, geospatial intelligence, product intelligence,
  underwriting referrals and bordereaux (BDX) data submission and observability — and
  the company states that its risk indices plug directly into Member underwriting and
  policy administration systems via API. Developer documentation is published at docs.accelerant.ai
  behind Member authentication; the platform publishes an anonymous OpenID Connect
  discovery document and JWKS at app.accelerant.ai.'

  description: 'The member-facing Accelerant Risk Exchange platform and its supporting
    API surface. Accelerant states that its risk indices plug directly into Member
    underwriting and policy administration systems via API, and it operates a dedicated
    API host at api.accelerant.ai alongside a Mintlify-hosted developer documentation
    site at docs.accelerant.ai. Both surfaces are gated: docs.accelerant.ai redirects
    unauthenticated requests to the Accelerant platform sign-in, and api.accelerant.ai
    is fronted by a WAF that returns HTTP 403 to anonymous requests. No machine-readable
    OpenAPI, GraphQL, AsyncAPI or MCP contract could be retrieved anonymously as of
    this profiling pass — see well-known/accelerant-well-known.yml for the full probe
    log. The platform does publish an anonymous OpenID Connect discovery document and
    JWKS.'
