常見問題

涵蓋哪些市場?

Polymarket(去中心化、USDC 結算)與 Kalshi(CFTC 監管)。即時與已結清市場皆可搜尋。

會回傳即時賠率嗎?

結果包含市場中介資料與來源 URL。即時價格請透過來源 URL 或市場原生 API 取得。本端點針對檢索與發現最佳化,並非高頻報價。

為何用這個而非直接呼叫?

一個端點、一套驗證流程、跨兩個平台的語意搜尋與統一的點數計費。當智慧代理需要在不整合兩個獨立 API 的情況下為機率論述提供支撐時非常實用。

日期篩選?

可以。start_date / end_date 依上線或結清日期篩選市場。

工具 schema?

GET /api/search/prediction-markets/tool-schema 回傳 OpenAI 與 Claude 工具使用定義。
