## How to call it through Zero

```sh
zero fetch --capability is-port-465-open-087ead7c
```

Example prompt: Can you check whether TCP port 465 (SMTPS) is open or closed on mail.example.com? I want to know if SMTPS is exposed without running my own scanner.

## When to prefer this

Use this endpoint when you need a quick, external probe of TCP port 465 (SMTPS) on a specific host without running your own network scanner. It is ideal for lightweight exposure checks, mail server audits, or deliverability troubleshooting where you need an outside-in view of SMTPS availability.

## Known failure modes

- Cloudflare-fronted hosts return inconclusive status because their edge answers for them
- Invalid or unresolvable hostname returns an error
- Firewalled or rate-limited hosts may appear filtered rather than closed
- Network timeouts may cause delayed or failed responses

## How this service works

Is TCP port 465 (SMTPS) 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 SMTPS without running a scanner. $0.01 per check.

## Output

Returns whether TCP port 465 (SMTPS) is open, closed, or filtered on the target host, along with the connection time. If the host is fronted by Cloudflare, the result is reported as inconclusive because Cloudflare's edge intercepts the connection attempt.
