Tool detail

Minifetch Technical SEO API

Extracts structured metadata from a URL — title, description, canonical, meta tags, Open Graph, Twitter Card, JSON-LD, redirects, headers and headings.

Categories: SEO marketing, Web scraping

Use when

  • pull Open Graph and Twitter Card tags for a URL
  • check a page's canonical URL and JSON-LD schema
  • audit a URL's meta tags for technical SEO

Not for

  • not full page content — metadata and headings only, no body text unless includeResponseBody is set
  • not a full SEO audit score — use minifetch's seo-page-audit for that

Inputs

GET query params: url (string, required); fields, includeResponseBody, omitEmpty (all optional)
