How this service works
Discover a site's XML sitemaps (via robots.txt Sitemap: directives, an explicit sitemap URL, or the conventional /sitemap.xml) and parse them into a bounded list of URLs with their lastmod, changefreq and priority. Follows sitemap-index files to their child sitemaps. Fetches and URL counts are capped (with a `truncated` flag) to stay fast and memory-bounded. The reliable way for an agent to enumerate a site's pages.
Output
A bounded list of URLs discovered from the site's sitemaps, each entry including the URL string and available metadata (lastmod, changefreq, priority). Sitemap-index files are followed to their child sitemaps. A `truncated` boolean flag indicates if the result was capped for performance. Fetches and URL counts are bounded to remain fast and memory-efficient.
Example use cases
Content audit for a blog
“Pull all the URLs from nytimes.com's sitemap so I can see every article they've published, along with when each was last updated.”
SEO competitor page discovery
“Discover all the pages on competitor.com by fetching their sitemaps — I want the full URL list with priority and changefreq so I can analyze their content strategy.”
Monitoring recently updated pages
“Get the sitemap for shopify.com and give me all the URLs sorted by lastmod so I can see which pages they've changed most recently.”
Technical details
Endpoint
POSThttps://web.openverbs.com/v1/sitemapWhen to prefer
Use this endpoint when you need to enumerate a site's pages systematically via its declared sitemap rather than crawling HTML links. Ideal for SEO analysis, content auditing, change monitoring, or building a seed URL list for a crawler. Prefer this over manual HTML scraping when the site publishes sitemaps, as it provides structured metadata (lastmod, changefreq, priority) and handles sitemap-index nesting automatically.
Side effects
- No sitemap found — site has no sitemap.xml, no Sitemap: directive in robots.txt, and no explicit sitemap URL provided
- Private/loopback/link-local URLs rejected with an error
- Sitemap malformed or not valid XML — parser returns error
- Site blocks sitemap fetches with 403/401 — returns HTTP error
- Truncated results when sitemap contains very large numbers of URLs — truncated flag set to true
- Network timeout if the target site is slow or unreachable
