WHAT IT ANSWERS

这张表适合回答什么

按标的和时间检索事件或原文
与行情联接研究事件前后反应

GRAIN & TIME

一行代表什么

业务粒度: 每行代表“IPO 日历”的一条记录；逻辑粒度由 ticker × announced_date × source 共同确定。
时间口径: 以 publish_ts 为主要查询时间轴；除下方限制特别说明外，时间戳按 UTC、日期按来源市场日历解释。
更新节奏: 通常按交易日或自然日更新；具体最新日期请以返回数据为准。

KEY FIELDS

先看这些字段

ticker: 来源或证券主表使用的股票代码。
announced_date: announced date 对应的日历日期。
source: 标准化数据来源；同一业务键可能因来源不同而有多行。

RECOMMENDED JOINS

怎样和其他表关联

该表主要按自身业务键使用，目前没有推荐的跨表主键联接。

HOW TO QUERY SAFELY

查询方法与已知限制

先用 catalog 确认当前契约；可按 catalog 中列出的 filters 进一步缩小范围；单页最多 5000 行，响应有 has_more 时原样传回 next_cursor 继续分页。

返回范围仍受 Friends 权限、单页上限和 catalog 中的筛选契约约束。

MACHINE CONTRACT

筛选、排序与分页

UNVERSIONED

默认排序: ticker, announced_date, source
唯一键: ticker, announced_date, source
读取模式: canonical_final_active
最大时间窗: 未单独限制

可用 filters

cik→ cik · string

provider→ provider · string

source→ source · string

ticker→ ticker · string

POINT IN TIME

可复现读取

NOT AVAILABLE

该资产没有 PIT 契约。普通 rows 端点仍按当前公开读模式返回数据；不要把它表述成历史时点快照。

COPY-READY CALLS

怎么调用

同一数据集可用 HTTP、Python SDK、CLI 或 MCP；Key 始终只通过环境变量/Bearer Header 传递。
