How this service works
Change watch for favicon finder: 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 favicon and app icon finder changes. $0.01 per check.
Output
Returns the current favicon and app icon data for the domain, a boolean 'changed' flag indicating whether anything differs from the previous call, a list of exactly which fields changed with their before and after values, and a timestamp of when the data was last seen. Previous results are retained server-side for 90 days per domain.
Example use cases
Brand relaunch icon detection
“Check if acmecorp.com's favicon or app icons have changed since last time — I want to know the moment they rebrand so I can update our competitive intelligence report.”
Scheduled site monitoring pipeline
“Run a favicon change check on myblog.io right now and tell me whether the icon has changed, what specifically changed, and when it was last seen.”
Multi-site icon drift alerting
“I need to know if shopify.com's favicon has changed compared to the previous check — give me the changed true/false flag and any before/after field differences.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/site/faviconWhen to prefer
Choose this endpoint when you need to track whether a site's favicon or app icons have changed over time, not just retrieve them once. It is specifically designed for scheduled polling workflows where the before/after diff and change flag are needed without storing state client-side. Prefer it over a one-shot favicon lookup when your agent needs to trigger alerts or downstream actions only on actual changes.
Side effects
- Domain not provided or invalid — request fails with an error
- No previous result exists (first call for domain) — changed flag may be false or undefined, no diff available
- Domain is unreachable — current favicon data may be empty or error state
- Stored result expired (>90 days since last call) — comparison baseline lost, treated as first call
- Rate limit or payment failure — request rejected
