}常见问题
覆盖了哪些来源?
arXiv(计算机、数学、物理等)、PubMed(生物医学)、bioRxiv(生物学预印本)和medRxiv(医学预印本)。一次调用并行查询全部四者。
为什么比其他垂直搜索API便宜?
开放访问的学术索引(arXiv、PubMed、bioRxiv、medRxiv)相对于专有的金融或法律数据集查询成本较低。积分价格反映了这一点。
可以限制日期范围吗?
可以。传入 start_date 和 end_date,格式为 YYYY-MM-DD,按发表日期过滤。
会返回论文全文吗?
不会 — 结果包含标题、摘要式片段、源URL和相关性评分。要获取任意论文全文,请对源URL调用 POST /api/extract。
有OpenAI / Claude的工具Schema吗?
GET /api/search/academic/tool-schema 返回可直接粘贴的OpenAI函数与Claude工具使用定义。
