How this service works
Change watch for keyword 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 keyword and topic extraction from a page changes. $0.01 per check.
Output
Returns the current keyword and topic extraction result for the URL, a boolean indicating whether it changed since the last call, a list of exactly which fields changed with before and after values, and a timestamp of when the result was last seen. The previous result is retained for 90 days for comparison.
Example use cases
Competitor landing page keyword tracking
“Monitor https://competitor.com/home for keyword changes — run the keyword-extract watch on a regular schedule and alert me any time the topics or keywords shift from what was there last time.”
SEO content drift detection
“Set up a recurring check on https://myblog.com/top-post using the keyword extract watch and tell me if the keywords or topics extracted from that page ever change from the previous result.”
Product page messaging change alert
“Watch https://brand.com/product for keyword extraction changes — I want to know the exact before and after values whenever the main keywords or topics on that page get updated.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/keywordsWhen to prefer
Use this endpoint when you need to detect changes in the keywords and topics extracted from a specific webpage over time, rather than doing a one-off extraction. It is ideal for scheduled monitoring workflows where you want to know exactly what changed (field-level before/after diffs) rather than just retrieving current keywords. Prefer this over a plain keyword extraction endpoint when change detection, scheduling, and historical comparison (up to 90 days) are requirements.
Side effects
- URL is unreachable or returns non-200 status — check will fail or return an error
- First call for a URL has no previous result to compare against — changed field may be undefined or false
- Previous result has expired after 90 days — comparison baseline is lost
- Malformed or missing URL input — returns input validation error
- Rate limiting or payment failure — call is rejected with payment-required error
