How this service works
Change watch for is ip heroku: runs the check, compares it with the result from your previous call for the same ip (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
Output
Returns the current is-Heroku boolean answer for the IP, a 'changed' true/false flag indicating whether the result differs from the previous call (stored up to 90 days), the specific fields that changed with their before and after values, and a timestamp of when the IP was last seen.
Example use cases
Detect Heroku migration for a competitor's server
“Watch the IP 52.73.214.10 and alert me if it stops being classified as a Heroku IP — show me the before and after values when it changes.”
Monitor your own app's IP hosting status
“I moved my app off Heroku recently — keep checking 54.165.200.91 and tell me once the Heroku classification flips to false so I know the DNS has fully propagated.”
Security audit: flag IPs that join Heroku
“I'm auditing traffic from 18.232.45.77 — run a watch check and tell me whether its Heroku status has changed since you last checked, with the full before/after diff.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/is/heroku?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to continuously monitor whether a specific IP address remains on or transitions to/from Heroku infrastructure over time, and want automated diff tracking (before/after values) without managing your own state. Prefer this over a one-shot check when you intend to schedule periodic polling and need change-alerting semantics built in.
Side effects
- Invalid or malformed IP address returns an error response
- No previous result stored (first call for this IP) — 'changed' will be null or false with no before value
- IP address is IPv6 when only IPv4 is supported
- Service unavailable or timeout from upstream Heroku IP data source
- Payment failure or insufficient USDC balance blocks the $0.02 per call charge
