GET /content/metadata
live
Extract structured metadata from any web page — title, author, publication date, Open Graph tags, canonical URL, language, word count, reading time. Handles HTML meta tags, og: tags, and article:published_time. No web scraping setup needed — one call returns structured JSON. Accepts USDC payments on Base and Solana
Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-02).
