Field notes
The pricing table distinguishes a wide set of operations, including a sitemap-and-link map of up to 1,000 URLs and same-host crawling of 1–50 pages. The quick start describes a payment handshake rather than requiring an API key, and the page links integration guides for tools including Claude Code, Cursor, VS Code, LangChain, and n8n. These are details presented on the homepage, not independent performance checks.
