## How to call it through Zero

```sh
zero fetch --capability is-port-554-open-1a597a39
```

Example prompt: Can you check whether TCP port 554 (RTSP) is open or closed on the host 192.168.1.100? I want to know if it's exposed without having to run a scanner.

## When to prefer this

Choose this endpoint when you need a quick, lightweight check of RTSP (port 554) exposure on a specific host without deploying your own port scanner or network tooling. Ideal for security audits, pre-deployment readiness checks, or confirming that a streaming server is reachable. Note the $0.01 per-call cost and the Cloudflare inconclusive limitation — if the target is behind Cloudflare, results will not be definitive.

## Known failure modes

- Host is behind Cloudflare — result returned as inconclusive since Cloudflare's edge intercepts the connection
- Host unreachable or DNS resolution failure — may return filtered or error state
- Timeout on connection attempt — port may be reported as filtered rather than closed
- Invalid hostname or IP format provided — likely returns an error or empty result
- Transient network issues from Cloudflare's edge — may produce inconsistent open/filtered results

## How this service works

Is TCP port 554 (RTSP) 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 RTSP without running a scanner. $0.01 per check.

## Output

Returns the port status (open, closed, or filtered) for TCP port 554 on the target host, along with the TCP connect time in milliseconds. If the host is behind Cloudflare's edge network, the result is marked as inconclusive since Cloudflare answers on behalf of the origin.
