How this service works
Change watch for meta tags all: 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 every meta tag on a page changes. $0.01 per check.
Output
Returns the current full meta tag snapshot for the URL, a boolean 'changed' flag indicating whether any tags differ from the previous check, a list of exactly which fields changed with their before and after values, and the timestamp of when the previous state was last seen. Results are retained for 90 days per URL.
Example use cases
SEO meta tag change alerting
“Check https://competitor.com for any meta tag changes since the last scan and tell me which tags changed, what they were before, and what they are now.”
OG tag drift monitoring for content team
“I need to track all the Open Graph and meta tags on our product page at https://mystore.com/products/widget — run a change check and flag anything that's different from the last time.”
Automated site integrity watchdog
“Set up a recurring watch on https://mybrand.com so I get notified whenever any meta tag changes — especially the robots or canonical tags — and show me before and after values when something shifts.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/meta-allWhen to prefer
Choose this endpoint when you need to detect any change across all meta tags on a page in a single call, with built-in diffing (before/after values) and 90-day result retention. Prefer it over manually scraping and comparing meta tags yourself, or over single-field watchers when you want comprehensive coverage of every meta tag at once on a schedule.
Side effects
- URL is unreachable or returns non-200 response — check will fail or return error
- First-time call for a URL has no previous snapshot to compare against — 'changed' may be null or baseline is set
- URL redirects to a different page — may track the destination instead of the source
- Payment failure via x402 protocol — request not processed
- No meta tags present on the page — returns empty snapshot
