Product Summary

AlterLab is an enterprise-grade web scraping API designed specifically for LLM and RAG pipelines. It bypasses anti-bot systems and extracts data from JavaScript-heavy sites, PDFs, and dynamic content with sub-2-second response times. Unlike general scrapers that output markdown dumps, AlterLab delivers structured JSON output optimized for AI consumption with tiered pricing by page complexity.

It provides managed browser infrastructure, proxy rotation, and data storage for large-scale web data extraction. Apify is widely used for feeding web data into AI applications and RAG pipelines.
