How this service works
Change watch for lead card: runs the check and compares it with the result from your previous call for the same domain (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 lead card changes. $0.01 per check.
Output
Returns the current lead card data for the domain, a boolean `changed` flag indicating whether any fields differ from the previous check, a field-level diff listing exactly which fields changed with their before and after values, and a timestamp of when the data was last seen. Previous results are retained for 90 days for comparison.
Example use cases
Sales lead data change alert
“Check if the lead card for stripe.com has changed since the last time you looked — tell me which fields are different and what the before and after values are.”
Automated CRM enrichment refresh
“I need to monitor notion.so's lead card on a schedule — run a check now and tell me if anything changed compared to the previous check 90 days ago, so I can update our CRM.”
Competitive intelligence tracking
“Watch the lead card for linear.app and flag any changes, specifically if their phone number, email, or company description has been updated since your last check.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/lead-cardWhen to prefer
Use this endpoint when you need to track changes to a specific website's lead card over time rather than doing a one-off lookup. It is ideal for scheduled polling workflows where you want field-level diffs with before/after values rather than just the current state. Prefer this over a plain lead card lookup when your goal is change detection and alerting rather than initial data retrieval.
Side effects
- Domain not found or unreachable — no lead card data returned
- No previous check exists for the domain — first-call baseline with changed=false
- Previous check older than 90 days — comparison window expired, treated as new baseline
- Invalid or missing domain input — request rejected
- Rate limiting or payment failure — call not processed
