SpellzCode — Link preview metadata for a page
https://agent-data-tools.revmesh2074.workers.dev/url/meta?url=https%3A%2F%2Fgithub.com%2FOverview
Fetch a public web page's head and return link-preview metadata: title, description, site name, type, preview image, canonical URL, language, author, published time, favicon, theme colour, and every OpenGraph and Twitter-card field. Reads at most 512 KB and never runs JavaScript. Use to build link previews, label citations or check how a URL will unfurl before sharing it.
