Accelerant

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.

Accelerant publishes 1 API on the APIs.io network. Tagged areas include Insurance, Insurtech, Specialty Insurance, Underwriting, and Risk Management.

Accelerant’s developer surface includes documentation, support, engineering blog, product news, authentication, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/accelerant: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →

  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.'
