Audit any URL and get the four Lighthouse categories — performance, accessibility, best-practices and SEO — alongside Core Web Vitals (LCP, CLS, INP). Because it runs on the same hosted Chromium as our capture engine, you also get a full-page screenshot of exactly what was measured, so a score always has a picture attached.
Wire the same audit into the ScreenshotInk API and the MCP server: run it in CI on every deploy, track scores over time, or let an AI agent audit a page and reason over the result. Same key, same quota.
