How this service works
Is TCP port 7 (Echo) open on a host? Attempts a connection from Cloudflare's edge and reports open/closed/filtered with the connect time; Cloudflare-fronted hosts are reported as inconclusive because their edge answers for them. Exposure checks for Echo without running a scanner. $0.01 per check.
Output
Returns the status of TCP port 7 on the target host: open, closed, or filtered, along with the connection time in milliseconds. If the host is behind Cloudflare's edge, the result is marked as inconclusive since Cloudflare answers on the host's behalf.
Example use cases
Security audit for exposed Echo port
“I need to know if TCP port 7 (Echo) is exposed on our public-facing server at 198.51.100.10 — can you check if it's open, closed, or filtered from the internet?”
Pre-deployment exposure check
“Before we go live, can you verify that port 7 is not open on the host api.example.com? We want to make sure the Echo service isn't accidentally exposed.”
Incident investigation for anomalous traffic
“We're seeing weird traffic logs and suspect port 7 might be open on 192.0.2.55 — can you probe it and tell me the connection time if it's reachable?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/port/7?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly verify whether TCP port 7 (Echo) is externally reachable on a specific host without running a local port scanner. It is ideal for lightweight, on-demand security exposure checks, pre-deployment audits, or incident investigations where you need a remote perspective from Cloudflare's edge network. Prefer this over general port scanners when you specifically care about port 7 exposure and want a low-cost, programmatic check.
Side effects
- Host behind Cloudflare returns inconclusive result rather than actual port status
- Invalid or unresolvable hostname returns an error
- Firewall that silently drops packets may be reported as filtered rather than closed
- Network timeouts may cause indeterminate results
- Payment failure prevents the check from executing
