name: Moore Threads API Lifecycle
description: >-
  Moore Threads runs a disciplined release process for its SOFTWARE STACK — versioned release
  notes, archived history_version trees, and per-release platform validation matrices for the MUSA
  SDK, the Linux drivers, the cloud-native suite and the codec libraries. It runs no comparable
  process for its APIs. The AIBook speech APIs and the KUAE Cloud Coding Plan carry a path version
  and nothing else: no deprecation policy, no Sunset/Deprecation headers, no SLA for the API
  surface, and no status page anywhere on the mthreads.com or kuaecloud.net estate.
versioning:
  scheme: uri-path
  api_versions:
  - {api: AIBook Text-to-Speech, versions: [v1 (HTTP unary), v2 (WebSocket streaming)]}
  - {api: AIBook Speech Recognition, versions: [v1]}
  - {api: AIBook Streaming Voice Conversion, versions: [v1]}
  - {api: KUAE Cloud Coding Plan, versions: ['root (Anthropic protocol)', '/v1 (OpenAI protocol)'], note: The /v1 is the OpenAI specification's own path, not a Moore Threads version namespace.}
  policy_published: false
deprecation:
  policy_published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  note: >-
    No deprecation or sunset policy is published for any API. The only deprecation signal anywhere
    on the estate is the MUSA SDK history_version archive, which preserves superseded SDK release
    notes without stating a support window for them.
status_page:
  published: false
  probed:
  - {url: 'https://status.mthreads.com/', status: 000, verdict: does not resolve}
  note: >-
    No status page, no uptime history and no incident feed was found on mthreads.com,
    docs.mthreads.com or kuaecloud.net. A Moore Threads AIBook customer has no way to distinguish
    a service incident from their own integration fault except by reading in-band status codes
    3001/3002.
sla:
  published: partial
  documents:
  - name: KUAE Cloud bare-metal SLA
    url: https://docs.mthreads.com/kuaecloud/kuaecloud-doc-online/terms/baremetal_sla
    status: 200
    covers: KUAE Cloud bare-metal GPU instances
    note: >-
      This is an infrastructure SLA for rented GPU servers. It does not cover the Coding Plan
      inference endpoint or any AIBook speech API.
  - name: KUAE Cloud preview agreement
    url: https://docs.mthreads.com/kuaecloud/kuaecloud-doc-online/terms/preview_agreement
    covers: Preview/beta services on KUAE Cloud

deprecated_operations_note: No OpenAPI is published, so no operation-level deprecation flags exist to derive from.
