How this service works
Sitemap reader: list a site's URLs with lastmod (handles sitemap indexes) — Genesis402 / UnyKorn Operator Network
Output
A structured list of URLs found in the site's sitemap, each accompanied by its lastmod timestamp (when available). Handles both simple sitemap.xml files and sitemap index files that reference multiple sub-sitemaps, returning up to the specified limit (default 200, max 1000) of URL entries.
Example use cases
Audit a site's published pages
“Get me a list of all the pages on stripe.com from their sitemap, with last-modified dates. Show up to 1000 results so I can see what content they publish.”
Track content freshness for SEO
“Pull the sitemap for shopify.com and tell me which URLs have been updated most recently — I want to see the lastmod dates for up to 200 pages.”
Discover pages before scraping
“Before I start scraping, can you read the sitemap at https://docs.anthropic.com/sitemap.xml and list all the URLs it contains so I know what pages exist?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/web/sitemap?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate all publicly indexed pages of a website, especially when you want last-modified dates to prioritize fresh content. It is superior to manual URL discovery because it handles both flat sitemaps and sitemap index files automatically. Ideal for SEO audits, pre-crawl URL discovery, content monitoring, and competitive research where you need a full list of a site's pages without scraping every page.
Side effects
- Site has no sitemap.xml and none is discoverable — returns empty or error
- Sitemap is malformed or non-standard XML — parse error
- Domain does not exist or is unreachable — network/timeout error
- Sitemap is extremely large and limit is reached — partial results up to limit
- Password-protected or robots.txt-blocked sitemap — access denied
