How this service works
Change watch for sitemap urls: runs the check and compares it with the result from your previous call for the same url (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when sitemap url list changes. $0.01 per check.
Output
Returns the current list of sitemap URLs, a boolean 'changed' field indicating whether the list differs from the previous check (stored up to 90 days), a diff of exactly which fields changed with before/after values, and a timestamp of when the sitemap was last seen.
Example use cases
New page launch detection
“Watch the sitemap at https://mycompetitor.com/sitemap.xml and let me know the moment any new URLs appear — I want to catch when they publish new product pages.”
SEO content audit automation
“Schedule a daily check on https://myblog.com/sitemap.xml and alert me if any URLs are removed or added, showing me exactly what changed and when it was last seen.”
Competitor site monitoring
“Keep an eye on https://rivalsite.com/sitemap.xml for me — I want a report every time their sitemap changes, with the before and after list of URLs so I can see what they're launching.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/sitemapWhen to prefer
Use this endpoint when you need to detect changes to a website's sitemap URL list on a recurring schedule without managing your own state — it handles the before/after comparison and stores prior results for 90 days. Prefer it over generic HTTP polling tools when you want structured field-level diffs specifically for sitemaps rather than raw page content changes.
Side effects
- Target URL is unreachable or returns non-200 status — endpoint may return an error or empty result
- Sitemap is malformed XML — parsing may fail or return partial URL list
- No previous check stored (first call) — 'changed' flag may be indeterminate or false by default
- Sitemap is too large — may timeout or return truncated results
- Previous check data expired after 90 days — baseline lost, comparison resets
