How this service works
Change watch for extract article as json: runs the check, compares it with the result from your previous call for the same url (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
Output
Returns the current extracted article as JSON, a boolean 'changed' flag indicating whether anything is different from the previous check (retained for 90 days), a list of changed fields with their before and after values, and the timestamp when the article was last seen in its prior state.
Example use cases
Track news article edits
“Monitor this news article URL and let me know if any part of the article — headline, body, author, or publication date — has changed since the last check.”
Alert on product page article update
“Watch this product blog post and tell me whether the article content has changed, showing me exactly which fields are different and what the before and after values are.”
Audit article modifications over time
“Run a change check on this article page and give me the current article data, whether it changed, and which specific fields were modified since the last time it was checked.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/watch/page/article/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect and diff changes in article content on a specific URL over time, rather than simply extracting the article once. It is ideal for automated monitoring pipelines, editorial auditing, or scheduling repeated checks where knowing what changed (not just what the current state is) is essential.
Side effects
- URL is unreachable or returns a non-200 response
- Page does not contain a parseable article structure, resulting in empty or null output
- First call has no previous result to compare against, so 'changed' may be indeterminate
- Comparison data older than 90 days is purged, causing a baseline reset
- Payment of $0.02 USDC not fulfilled, blocking the request
