  • 限制:建议配置密钥
  • 用途:影响因子、分区

使用示例

// 搜索(默认使用 Europe PMC + PubMed)
{"keyword": "machine learning", "max_results": 10}

// 指定数据源搜索
{"keyword": "cancer", "sources": ["europe_pmc", "arxiv"]}

// 获取全文
{"pmcid": "PMC1234567"}

// 获取指定章节
{"pmcid": "PMC1234567", "sections": ["methods", "results"]}

// 批量获取
{"pmcid": ["PMC123", "PMC456"]}

// 获取参考文献(默认 Europe PMC + CrossRef)
{"identifier": "10.1038/nature12373", "max_results": 20}

// 文献关系分析
{"identifiers": "10.1038/nature12373", "relation_types": ["references", "similar"]}

// 期刊质量(EasyScholar + OpenAlex 双源)
{"journal_name": "Nature", "include_metrics": ["impact_factor", "h_index"]}

参数容错特性

get_article_details 工具会自动修正以下格式错误:

输入 自动修正为
"pmcid": "[\"a\", \"b\"]" ["a", "b"]
"sections": "methods" ["methods"]

API 限制汇总

API 限制 用途
Europe PMC 1 req/s 全文、参考文献
Crossref 50 req/s 参考文献
arXiv 3 req/request 预印本
OpenAlex 无限制 引用关系、指标
