}常见问题
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。
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。
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。
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。
工具Schema?
GET /api/search/prediction-markets/tool-schema 返回OpenAI与Claude工具使用定义。
