How this service works
Change watch for opengraph extract: 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 open graph and twitter card extractor changes. $0.01 per check.
Output
Returns the current OpenGraph and Twitter Card field values extracted from the URL, a boolean 'changed' flag indicating whether anything differs from the previous call's result (retained for 90 days), a detailed field-level diff listing exactly which properties changed with their before and after values, and a timestamp of when the page was last seen.
Example use cases
E-commerce product social card monitoring
“Watch https://shop.example.com/shoes/air-max for any changes to its OpenGraph or Twitter card tags — I want to know immediately if the og:title, og:description, or og:image gets updated compared to last time you checked.”
News article metadata drift detection
“Has the OpenGraph metadata on https://news.example.com/breaking-story changed since you last checked it? Show me which fields changed and what the before and after values were.”
Brand campaign launch verification
“We just pushed a site update — can you check if the og:image and og:description on https://brand.example.com/campaign have changed from what was there before, and confirm when this was last seen?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/opengraphWhen to prefer
Choose this endpoint when you need scheduled or on-demand change detection specifically for OpenGraph and Twitter Card metadata on a single URL, with field-level before/after diffs and a 90-day result memory. Prefer it over a generic scraper when you need structured social metadata diffing rather than raw HTML comparison, and over the bulk variant when monitoring a single URL on a polling schedule.
Side effects
- URL is unreachable or returns non-200 — extraction fails, no diff available
- No prior call stored for this URL — first-run returns current data with changed=false or null, no diff
- Stored result has expired (older than 90 days) — treated as first run
- OpenGraph tags absent on the page — empty extraction returned
- Payment not processed — request rejected before execution
