note: >-
  Toutiao publishes no versioning policy, no deprecation policy, no SLA and no status page.
  What it does have is two observable platform migrations, captured below from live 301/302
  redirect chains — that is real lifecycle evidence, but it is not a policy, and no
  Deprecation or StatusPage pointer is wired on the strength of it.
versioning:
  scheme: none-observed
  current: null
  docs: null
  detail: >-
    Endpoint paths on open.snssdk.com carry no version segment and no version header or
    date-pinning convention is documented.
deprecation:
  policy_url: null
  sunset_header: false
  policy_published: false
  detail: >-
    No RFC 8594 Sunset/Deprecation header support is documented and no deprecation policy
    page exists. Endpoint retirement has instead been communicated by silently redirecting
    the old host, as recorded in migrations[] below.

  detail: >-
    The Toutiao ads open platform has been folded into OceanEngine (巨量引擎), ByteDance's
    unified advertising platform. Advertising APIs are no longer a Toutiao-branded surface;
    they are catalogued under OceanEngine.
