为 AI 代理在你的 Postgres 上提供图、向量与文本检索
通过一个一致的接口同时查询图、向量、全文与混合检索，无需把多个系统拼在一起。
开源引擎 pgGraph 可跨记录沿关系遍历，无需搬迁数据即可实现多跳与最短路径式检索。
基于嵌入的语义搜索与稀疏、全文匹配相结合，兼顾语义与精确词条的查询需求。
仪表盘演练场、用于导入与配置的 CLI，以及强类型 Python SDK，让原型验证到正式上线一气呵成。
基于 Ahrefs 索引打造的独立网页搜索与 Agent 检索 API
提交查询即可获得来自独立索引的排序页面而非仅链接，避免依赖单一商业搜索提供商。
每条结果都包含可回答查询的段落，让语言模型无需解析整页即可读取相关上下文。
单个接口调用即可为模型返回开放网络上下文，专为 RAG 与 Agent grounding 工作流设计。
自 2010 年以来抓取约 1000 亿页面，每 24 小时刷新约 80 亿页面，结果保持相对新鲜。
