How this service works
Change watch for extract iframes 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 iframes as a JSON object, a boolean 'changed' flag indicating whether the iframe content differs from the previous check, a list of fields that changed with their before and after values, and a timestamp of when the result was last seen. Previous check results are retained for 90 days.
Example use cases
Detecting unauthorized iframe injection
“Watch https://mycompany.com for any changes to its iframes — if someone injects a new iframe or removes an existing one, I want to know immediately with the before and after details.”
Tracking third-party embed updates
“Check https://news-partner.com/embed-page to see if any of the iframes have changed since the last check, and tell me which ones are different and what changed.”
Scheduled compliance monitoring
“Monitor https://client-site.com/landing for iframe changes on a regular schedule — I need to know if any new embeds appear or existing ones are modified, with timestamps of when changes were last seen.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/watch/page/iframes/json?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect changes to iframes on a specific webpage over time, rather than just extracting them once. It is ideal for scheduled monitoring workflows, compliance checks for unauthorized embeds, or tracking third-party content updates. Choose this over the bulk or single-extract variants when change detection and diffing (before/after) is the primary goal.
Side effects
- URL is unreachable or returns a non-200 status — check may fail or return an error
- No previous check exists for the URL (first call) — 'changed' may be undefined or baseline-only
- Page requires JavaScript rendering — statically-fetched iframes may be incomplete
- 90-day retention window exceeded — previous result no longer available for comparison
- Rate limiting or access restrictions on the target page — extraction may be blocked
