summary: >-
  OneNET versions its APIs with a query parameter rather than the URL path, and pins the
  authorization signature algorithm to a dated version string. A dated release log and a
  platform announcement board exist. No deprecation policy, no Sunset/Deprecation header
  support, no SLA with an uptime target and no status page were found anywhere across the
  four China Mobile API estates.
versioning:
  scheme: query-parameter
  parameter: version
  current:
    onenet_studio_application_api: '1'
    onenet_voice_call_service: '2'
    onenet_auth_signature: '2020-05-29'
    iot_card_capability_platform: v2 (URI path segment)
  docs: https://open.iot.10086.cn/doc/iot_platform/book/api/introduce.html
  note: >-
    The auth reference states 2020-05-29 is "目前仅支持" — currently the only supported
    signature version — so the algorithm version is effectively frozen.
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  note: >-
    No deprecation policy, migration window or RFC 8594 Sunset/Deprecation header support
    is published. The documentation does carry an in-band deprecation signal of a sort:
    the OneNET Studio book renders a banner reading 该文档版本较低，请点击访问新版本文档 ("this
    documentation version is out of date, click for the new version") pointing at
    /doc/v5/develop, so an older generation of the platform docs is being superseded
    without a stated timetable.

    new: https://open.iot.10086.cn/doc/v5/develop
sla:
  url: null
  uptime_target: null
  note: >-
    No published SLA or uptime commitment. Service agreements exist for the products
    (公测服务协议, 位置定位服务协议, 语音通话服务协议, 工业互联网标识服务协议) but they are terms of service, not
    availability commitments.
status_page: null
status_page_note: >-
  No status page. The closest first-party surface is the OneNET 平台公告 (platform
  announcements) board at https://open.iot.10086.cn/doc/announcement, which carries
  maintenance and change notices but is not an availability dashboard. status.heclouds.com
  does not resolve.
