學術研究搜尋 API
透過單一端點查詢 arXiv、PubMed、bioRxiv 與 medRxiv 上的同行評審論文與預印本。預先成型的 JSON 輸出,可直接用於 LLM 工具呼叫、引用擷取與科學文獻 RAG。

}Rate limits
Throttling is per API key, sliding 60-second window. Hit the limit and you get a clean 429 with a Retry-After header.

}常見問題
涵蓋哪些來源?
arXiv(資訊、數學、物理等)、PubMed(生物醫學)、bioRxiv(生物學預印本)與 medRxiv(醫學預印本)。一次呼叫即可平行查詢全部四者。
為何比其他垂直搜尋 API 便宜?
開放存取的學術索引(arXiv、PubMed、bioRxiv、medRxiv)相對於專屬金融或法律資料集而言查詢成本較低。點數價格反映了這一點。
可以限制日期範圍嗎?
可以。傳入 start_date 與 end_date,格式為 YYYY-MM-DD,即可依發表日期篩選。
會回傳論文全文嗎?
不會 — 結果包含標題、類摘要片段、來源 URL 與相關性分數。要取得任意論文全文,可對來源 URL 呼叫 POST /api/extract。
OpenAI / Claude 工具 schema 呢?
GET /api/search/academic/tool-schema 回傳可直接貼上的 OpenAI 函式與 Claude 工具使用定義。
