663 endpoints, organized into primitives, service APIs, and integration endpoints.
Most 1health API categories are Primitive — canonical healthcare objects like Order, Person, Encounter, and Organization. A smaller set are service configuration APIs (Workflow Template, Audit Log, API Statistics) that manage running services, and a few are integration endpoints (OpenAI Proxy, Twilio, GraphQL).
