API介绍
来自Google的开源项目LangExtract：https://github.com/google/langextract
LangExtract 是 Google 出品的一个 Python 库，专注于「使用大语言模型（LLMs）从非结构化文本里提取结构化信息」。它的核心功能包括：
可以根据你的自定义规则和示例，从文本（如医疗报告、文学著作等）中提取实体、属性和关系等结构化数据。
能将结果与原始文本进行精准定位，可以很方便地实现高亮、可视化等检查或溯源。
特别适合长文本，比如一次性解析整本小说/医疗长报告，用分块并行和多次迭代提升召回率。
内置互动式 HTML 可视化，可以把抽取结果在网页里生动展示。
价格：根据模型调用的价格来计算
