## Firecrawl Crawl

### What it is
Firecrawl crawls websites to extract comprehensive data while bypassing blockers.

### How it works
<!-- MANUAL: how_it_works -->
This block uses Firecrawl's API to crawl multiple pages of a website starting from a given URL. It navigates through links, handling JavaScript rendering and bypassing anti-bot measures to extract clean content from each page.

Configure the crawl depth with the limit parameter, choose output formats (markdown, HTML, or raw HTML), and optionally filter to main content only. The block supports caching with configurable max age and wait times for dynamic content.
