使用场景
从网站构建 RAG 知识库
爬取完整的文档站点或公司域名,将页面转换为干净的 Markdown,以供向量数据库 ingest,用于检索增强生成(RAG)。
为 AI 代理提供最新网页上下文
通过按需抓取目标 URL,并在一次 API 调用中返回适用于 LLM 的 Markdown,向自主代理提供最新信息。
使用 Schema 抽取结构化数据
定义 JSON Schema,从页面中提取价格、联系人或产品规格等特定字段,即使内容是通过 JavaScript 渲染的。
生成 LLM 训练数据集
利用全站爬取、代理轮换和反机器人防护,构建大规模、已清洗的文本语料库,以用于微调语言模型。

Does the job
Pretty happy overall. Schema-based structured data extraction just works and outputs clean markdown optimized for LLMs. Usage-based pricing can scale up quickly can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.
Years in this space
I've evaluated a lot of these over the years. What stands out here is javaScript rendering and anti-bot handling — handled better than most — and single API for crawling, scraping, and structured extraction. Worth the time if this is your use case.

Solid for our team
We rolled this out across the team last quarter and handles JavaScript rendering and dynamic pages. Self-hostable open-source version fits neatly into how we already work, and full-site crawling with one endpoint removed a step we used to do by hand. Some sites still block automated crawling, which is the main caveat, but it has held up under daily use.
