How this service works
Track public RSS, Atom or XML feed content and report normalized additions and removals.
Output
A normalized report of feed entry additions and removals, including item identifiers, titles, publication dates, and links for each changed entry, structured to clearly distinguish new items from deleted ones.
Example use cases
New blog post alert monitoring
“Watch this Atom feed at https://techblog.example.com/atom.xml and tell me whenever a new article gets added or an old one gets pulled down.”
Podcast episode change tracking
“Check the RSS feed at https://podcast.example.com/rss for any episodes that have been added or removed compared to the last snapshot.”
Job listing feed diff
“Monitor this XML job listings feed at https://careers.example.com/jobs.xml and report back any new job postings that appeared or any that were taken down.”
Technical details
Endpoint
POSThttps://9dmb38pvlp8dr1d3rtfjpe934o.ingress.h4i-dedicated.eu-sw-2.digitalfrontier.so/api/seller/v4/public-data/feed-changeWhen to prefer
Choose this endpoint when you need to diff a public RSS, Atom, or XML feed to surface exactly which items were added or removed, with normalized output. It is distinct from general webpage change detection (which handles arbitrary HTML) and JSON/CSV dataset tracking (which handles structured data tables). Prefer this when your target is a syndication feed format specifically.
Side effects
- Feed URL is unreachable or returns a non-200 HTTP status
- URL does not point to a valid RSS, Atom, or XML feed — returns a parse error
- Feed requires authentication and is not publicly accessible
- Feed returns malformed or non-standard XML that cannot be normalized
- Rate limiting or network timeouts from the feed host
