is-port-7-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 7 (Echo) is open on a host and returns a change diff compared to the previous check, alerting when the status changes.

How this service works
Change watch for is port 7 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 state of TCP port 7 on the specified host, a boolean indicating whether the state changed since the previous call, a list of fields that changed with before and after values, and the timestamp of when the state was last seen. Previous results are retained for 90 days.
Example use cases
Detect unauthorized Echo port exposure
“Watch port 7 on my server at 198.51.100.10 and alert me if it ever changes from closed to open — I need to know immediately if the Echo port becomes exposed.”
Track port 7 flapping during maintenance
“Check whether port 7 is open on 203.0.113.77 right now and tell me if the status has changed compared to the last time you checked, including when it was last seen.”
Periodic infrastructure health polling
“Poll port 7 on 192.0.2.55 on a schedule and notify me whenever its open/closed state changes — I want a before-and-after diff each time it flips.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/port/7?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect state changes in TCP port 7 availability over time rather than just querying the current status. Ideal for scheduled polling workflows where you want diff-based alerting — knowing not just the current state but whether it changed, what changed, and when. Prefer this over the plain is-port-7-open check when building monitors, alert pipelines, or anomaly-detection workflows.
Side effects
- Host unreachable or invalid — check may return error or indeterminate state
- No prior check stored (first call) — 'changed' will be false or undefined as there is no baseline
- 90-day retention window expired — baseline discarded, comparison unavailable
- Rate limiting or payment failure — $0.02 USDC charge not authorized, call rejected
- Firewall or edge network timeout — connection attempt may time out rather than cleanly reporting closed
