Free tool — no signup required
One call returns the title, description, og:image, og:site_name, html lang and favicon a page exposes for link previews — with a plain checklist of which are set and which are missing.
The link-preview / meta reader is one of nine checks in the full API — SEO audit, tech stack detection, security-header grading, public contacts, and AI-ready Markdown, all from the same one HTTP call. Free tier, 1,000 requests/month, no card required.
