  description: >-
    REST API for the Akute Health automation-first EHR platform. Exposes
    FHIR-aligned resources - patients, appointments, clinical notes
    (encounters), tasks, documents, medications and e-prescribing, lab orders,
    diagnostic reports and observations - plus webhook subscriptions for
    resource events. Authentication uses an API key passed in the X-API-Key
    header. Webhook deliveries are signed with HMAC-SHA256 in the
    x-akute-signature header.
