The web data API for AI agents — search, scrape, map, and crawl any site into clean markdown or JSON.

Use the managed cloud for zero infra, or self-host the same open-source engine. Start with Python, TypeScript, cURL, or MCP — you never touch Rust.

Beats Firecrawl and Crawl4AI on truth-recall — measured on Firecrawl's own public dataset.

Quickstart — your first scrape in 30 seconds

export CRW_API_KEY="crw_live_..."
