WebberSites x402 Data API.

GET https://api.webbersites.com/api/seo/metadata ↗

Raw metadata extractor: the complete, unopinionated head inventory of a page — title, charset, lang, canonical, all meta tags grouped by family (OpenGraph, Twitter, Dublin Core, named, http-equiv, itemprop), every link relation, and JSON-LD returned as parsed objects. For agents doing their own processing (head-check audits the same data; this just dumps it). ?url=
