• 提取元数据

使用示例 搜索示例 用户：帮我搜一下多智能体编队控制的论文 → 调用OpenAlex API搜索 "multi-agent formation control" → 返回top 10结果，按被引量排序 → 展示标题、作者、年份、被引量、期刊

下载PDF示例 用户：这篇论文能下载吗？DOI: 10.1109/tie.2017.2701778 → 检查OpenAlex的open_access字段 → 如果是OA，提供下载链接 → 如果不是OA，建议其他获取方式

引用导出示例 用户：帮我生成这篇论文的APA引用 → 解析元数据 → 生成APA 7th格式：Ge, X., & Han, Q.-L. (2017). Distributed Formation Control... IEEE Transactions on Industrial Electronics. https://doi.org/...
