Arthur is an enterprise AI governance and observability platform for discovering, monitoring, evaluating, and governing AI and ML systems in production. The Arthur Platform API (internally "Arthur Scope", OpenAPI 3.1) exposes 213 operations across models, tasks, datasets, connectors, metrics, alerts, alert rules, policies, workspaces, projects, agents, and webhooks, secured with OAuth2 via Keycloak. Arthur also ships the open-source Arthur Engine (LLM guardrails plus ML evaluation), the arthur-bench LLM evaluation library, Python client SDKs, and an Agent Toolkit with a Claude Code integration for end-to-end tracing.
