ArthurAI

Arthur is an enterprise AI governance and observability platform — an "AI control plane" to detect, govern, and improve AI across an organization. It provides agent discovery across OTEL/MCP/network/cloud APIs, end-to-end agentic tracing and observability, LLM-as-a-judge evaluations, guardrail rules that validate prompts and responses, and organization-wide monitoring policies. Arthur exposes two public REST APIs: Arthur Scope (observability, connectors, datasets, metrics, alerts, and policy governance) authenticated with OAuth2, and the Arthur GenAI Engine (tasks, guardrail rules, prompt and response validation, inferences, and feedback) authenticated with a bearer API key. Deployable as SaaS, hybrid, or on-premises, with first-party Python SDKs and an official Claude Code onboarding skill.

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles ArthurAI the way a machine reads it — 73 machine-readable artifacts across 68 APIs, 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 — ArthurAI scores 52.2/100 (developing), with a separate agent-readiness read of 61/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

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 ArthurAI

Each block below is one kind of artifact we hold for ArthurAI. 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 68

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.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

AsyncAPI definitions for this provider's event-driven and streaming APIs.

Security Posture 2

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.
