常见问题

01

覆盖哪些市场？

Polymarket（去中心化、USDC结算）和Kalshi（CFTC监管）。实时与已结算市场均可搜索。

02

会返回实时赔率吗？

结果包含市场元数据与源URL。实时价格请通过源URL或市场原生API获取。本端点针对检索与发现进行了优化，并非高频报价。

03

为什么用这个而不是直接调用？

一个端点、一套鉴权流程、跨两个平台的语义搜索和统一的积分计费。当智能体需要在不集成两个独立API的情况下为概率论断提供支撑时非常有用。

04

可以按日期过滤吗？

可以。start_date / end_date 按上线或结算日期过滤市场。

05

工具Schema？

GET /api/search/prediction-markets/tool-schema 返回OpenAI与Claude工具使用定义。
