Feed/Sitemap Digest (public URL heuristic)

Public-web Feed/Sitemap Digest for agents. Pass 1–5 http(s) URLs; get normalized items (url, title, date when present) from RSS, Atom, or sitemap XML (up to 50 items per source). HTML pages: discovers an alternate feed or sitemap.xml and fetches one hop. Safety-limited (timeout, size, redirects) and refuses private/local hosts. Heuristic best-effort — not a full feed validator, not financial advice.
