x402
is-port-111-open-watch is a paid API for AI agents from ip.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).
Monitors whether TCP port 111 (portmapper/rpcbind) is open on a host, returning the current status plus a change-detection diff against the last call for that host within 90 days.

How this service works
Change watch for is port 111 open: runs the check, compares it with the result from your previous call for the same host (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 open/closed status of TCP port 111, a boolean 'changed' field indicating whether the result differs from the previous call for the same host, a list of fields that changed with their before and after values, and a timestamp of when the port status was last seen. Previous results are retained for 90 days per host.
Example use cases
Detect rpcbind exposure on production server
“Check port 111 on my production server at 198.51.100.10 and tell me if its open/closed status has changed since the last check — I need to know immediately if rpcbind becomes exposed.”
Scheduled NFS portmapper security audit
“Run the port 111 change watch on 203.0.113.77 and report back whether anything changed from the previous result, with before and after values so I can log it in our security audit trail.”
Alert on unexpected port 111 opening
“I want to be alerted if port 111 suddenly opens on 192.0.2.55 — run the change watch now and show me the changed flag and what fields differ from the last known state.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/port/111?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need change-aware monitoring of TCP port 111 (portmapper/rpcbind) specifically, and want to be notified only when the status changes rather than receiving a raw status every time. It is ideal for scheduled security monitoring pipelines where detecting the moment port 111 becomes exposed or closes is more valuable than a simple point-in-time check. Prefer the non-watch sibling endpoint if you only need a single current status without change detection.
Side effects
- Host unreachable or invalid hostname returns an error or indeterminate port status
- No prior result stored for the host (first call) results in 'changed' being undefined or false with no before values
- 90-day result expiry means old baselines are lost and first check after expiry has no comparison
- Network timeout from Cloudflare edge yields inconclusive open/closed result
- Payment failure via x402 protocol prevents the check from executing
