About Webcrawler API
Webcrawler API is a hosted web crawling and data extraction service that turns pages from websites, documentation and help centers into cleaned markdown for AI support agents and knowledge products. It loads a page, removes menus, cookie banners, footers and ads, and returns formatted markdown intended for use in prompts, indexing or storage.
The service handles JavaScript rendering, CAPTCHAs, anti-bot protection, residential proxies, automatic retries and rate limit handling on its side. It offers smart caching for frequently requested pages and change-detection feeds that report changed pages, new additions, removals and diffs. Crawling is driven through a REST API, with code examples for several languages and documented no-code integrations.
