How this service works
Change watch for extract scripts 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 script tags as a JSON object, a boolean 'changed' flag indicating whether scripts differ from the previous call, a list of fields that changed with before and after values, and the timestamp of when the page was last seen. Previous results are retained for 90 days for comparison.
Example use cases
Competitor tracking pixel surveillance
“Watch https://shop.competitor.com for any changes to its script tags — I want to know immediately if they add or remove any analytics or ad pixels compared to the last time you checked.”
Supply chain script integrity check
“Monitor https://checkout.mybusiness.com and alert me if any of the scripts on the page change — I need to detect any unauthorized third-party scripts being injected.”
Scheduled SaaS update detection
“Check https://app.mytool.io for changes to its loaded scripts and tell me what's different from the last scan, including which scripts are new or gone.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/watch/page/scripts/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes to script tags on a specific web page over time, particularly for security monitoring (unauthorized script injection), competitive intelligence (new analytics or ad tools), or compliance checks. It is purpose-built for change detection with before/after diffing and 90-day history, making it superior to a plain script extraction endpoint when temporal comparison matters.
Side effects
- URL is unreachable or returns non-200 status — check returns error or no data
- No previous call exists for the URL — first call has no baseline to compare against, changed may be null or false
- Page requires authentication or JavaScript rendering — scripts may be incomplete or missing
- URL redirects — may cause comparison drift if redirect destination changes
- 90-day history window exceeded — baseline lost, comparison resets
