## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability is-port-514-open-8a766324
```

Example prompt: Can you check whether TCP port 514 (syslog) is open or blocked on the host 203.0.113.45? I want to know if it's exposed to the internet without running a full port scanner.

## When to prefer this

Use this endpoint when you need a quick, passive check of whether TCP port 514 (syslog) is exposed on a host without deploying your own scanner or running nmap. Ideal for security audits, compliance checks, or pre-deployment exposure verification where you want a lightweight, remote perspective from Cloudflare's edge. Not suitable for hosts behind Cloudflare CDN, where results will always be inconclusive.

## Known failure modes

- Cloudflare-fronted hosts always return inconclusive regardless of actual port state
- Connection timeout may cause the result to be reported as filtered rather than closed
- Invalid or non-routable IP addresses may return an error or filtered status
- Rate limiting or network-level blocks at Cloudflare's edge may affect accuracy

## How this service works

Is TCP port 514 (syslog) 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 syslog without running a scanner. $0.01 per check.

## Output

Returns the status of TCP port 514 on the target host — one of open, closed, or filtered — along with the TCP connect time in milliseconds. If the host is behind Cloudflare's edge, the result is flagged as inconclusive because Cloudflare's infrastructure answers the connection attempt on behalf of the origin.
