x402
is-port-22-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 2026-10-13).
Monitors whether TCP port 22 (SSH) is open on a host and returns whether the status has changed since the last check, with before/after diff values.

How this service works
Change watch for is port 22 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 boolean status of port 22 (open/closed), a 'changed' true/false flag indicating whether the status differs from the previous cached result (retained 90 days), a list of fields that changed with before and after values, and a timestamp of when the status was last observed.
Example use cases
SSH exposure alert on production server
“Watch port 22 on 198.51.100.10 and let me know immediately if its SSH port status changes — I need to know the moment it opens or closes.”
Security audit for unexpected SSH access
“Check if port 22 on 192.0.2.77 has changed state since the last check — I'm auditing whether SSH was unexpectedly exposed on that host.”
Infrastructure health monitoring for SSH daemon
“Is port 22 still open on my server at 203.0.113.99? Tell me if the status is different from what it was before, including what changed and when it was last seen.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/port/22?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need change-detection semantics for port 22 (SSH) monitoring — not just a one-time check, but a stateful watch that compares the current result against a cached prior state and explicitly tells you what changed. Ideal for scheduled polling workflows where you want to be alerted only on transitions (open→closed or closed→open), avoiding noise from repeated identical states. Prefer the non-watch sibling for one-off checks with no change comparison needed.
Side effects
- Host unreachable or invalid IP/hostname returns an error or inconclusive port status
- No previous result cached (first call for this host) may return changed=false or null diff
- Network timeout from Cloudflare edge may produce indeterminate open/closed result
- Cached result expired after 90 days resets the comparison baseline
- Rate limiting or payment failure returns a 402 or error response
