Arbital Health
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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Arbital Health the way a machine reads it — 6 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Arbital Health scores 29.9/100 (thin), with a separate agent-readiness read of 9/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
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).
An API exists — we simply could not reach the contract without credentials or a sales conversation. This one is Arbital Health's to change: publishing the reference and a machine-readable spec at a public URL, while keeping key issuance behind whatever gate they like, would let an integrator evaluate the API before committing to a call.

Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Arbital Health
Each block below is one kind of artifact we hold for Arbital Health. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Arbital Health Platform API
The JSON API behind the Arbital Health adjudication platform at platform.arbitalhealth.com. Observed live and returning JSON, but every resource path answers 401 {"error":"Unaut...
Security Posture 4
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Arbital Health, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
