CurlShot is a screenshot API: one HTTP request turns a URL, HTML or Markdown into a PNG, JPEG, WebP, PDF or scrolling video. Ships llms.txt, llms-full.txt, a markdown twin of every docs page, an OpenAPI 3.1 file and a hosted MCP server for AI agents.
Submitted URLs are declarations until checked. Verification inspects published content and does not execute third-party tools.
The score measures observable documentation quality. Each component below lists its earned points, exact checks, and source observations. It is not a prediction of AI rankings or citations.
