  • item/{id}.json 读取故事、评论、工作、poll 或 pollopt；user/{caseSensitiveId}.json 读取有公开活动的用户。
  • 榜单包括 topstories、newstories、beststories、askstories、showstories、jobstories；maxitem 与 updates 提供最大 ID 和变化列表。
  • print=pretty 是 README 示例的可选展示参数。

Outputs

  • 榜单返回整数条目 ID 数组；top/new 最多500条，Ask/Show/Job 最多200条。
  • item 可包含 id、type、by、time、title、text、url、score、kids、parent、deleted、dead 等，按条目类型可缺字段；title/text 可为 HTML。
  • user 可含 id、created、karma、about、submitted；updates 返回 items 与 profiles 的 ID 列表。

Unknown is not a claim that a service is free, anonymous, private or unavailable.

Limitations

  • 文档称当前 no rate limit；该陈述仅记录捕获时说明，不能保证未来配额或服务能力。
  • 评论子树与条目详情需要多次按 ID 访问，榜单本身不返回完整文章正文。
  • 只有有公开评论或提交活动的用户可由此 API 获取；不是私有账户或写入接口。
  • v0 可能演进；应容忍新增字段，正确处理 deleted/dead 与 HTML 文本。

Unknowns

  • 认证与费用条款、SLA、请求日志保留未知。
  • 实际近实时延迟、当前数据、服务可用性和未来限流变化未验证。

Fixed profiles, conditions and evidence

Read state: not_checked; review state: unknown. Do not combine different profiles.

资料与来源声明不等于本站实测；未列出的条件仍未知。

结构化配方只按公开声明检查约束与接口，不执行任务或授予权限；缺失记录保持未知，接口兼容不证明实际成功。
