AI data extraction: how to extract structured data from websites at scale

AI data extraction leverages large language models and AI-native APIs to efficiently extract structured, schema-conformant data from websites without relying on fragile CSS selectors or XPath expressions, which often break with layout changes. This method involves a three-step process utilizing the Search API for URL discovery, the Extract API for converting web pages to clean markdown, and the Task API for enforcing a JSON schema, enabling the transformation of raw web data into structured formats like markdown, compressed excerpts, or JSON. This approach offers resilience to layout changes, reduces maintenance burdens, and lowers token costs by pre-cleaning data, unlike traditional web scraping that processes raw HTML. AI-driven extraction proves more accurate and efficient than conventional methods, with research showing significant improvements in processing efficiency and extraction accuracy. The system supports high-volume extraction with predictable costs, making it suitable for enterprise applications, while ensuring compliance with data privacy standards through features like SOC 2 Type 2 certification and zero data retention. Users can define objectives in plain English to specify the desired data output, enhancing the adaptability of AI extraction across diverse web sources and ensuring consistent results with schema-driven output.
