- 解析证券与来源标识映射
- 为跨表查询补充分类和主数据
DATASET · ref
ref.option_contract
这是证券主数据、交易日历与跨来源映射中的“期权合约主表”数据集;一行由 underlying_ticker、expiration_date、strike_price、contract_type 定位,主要字段包括 ticker、exercise_style、shares_per_contract、primary_exchange、cfi。

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
先用 catalog 确认当前契约;必须提供 ticker;单页最多 5000 行,响应有 has_more 时原样传回 next_cursor 继续分页。

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
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。
