Sitemap.xml URL inventory API

Fetches a sitemap.xml (or sitemap index) and parses it into a flat URL inventory with ISO lastmod, changefreq, and priority; sitemap-index files are transparently expanded one level. The value-add: nested index + urlset structures collapse into one normalized URL list. Answers 'list all URLs in this sitemap', 'get the sitemap inventory for this domain', 'when was this page last modified per the sitemap', 'expand this sitemap index'.
