```sh
zero fetch --capability stableemail-status-8ddad223
```

Example prompt: Check whether my StableEmail subdomain 'newsletters.mycompany' has finished DNS and SES verification — is it ready to send email?

## When to prefer this

Use this endpoint when you need to confirm that a custom StableEmail subdomain's DNS and SES records are properly configured and verified before attempting to send email through it, or to diagnose delivery issues caused by incomplete subdomain setup.

## Known failure modes

- Subdomain not found — if the subdomain doesn't exist in StableEmail's system, returns an error or empty status
- DNS not yet propagated — status may show unverified even if records were recently added
- Missing required subdomain parameter — returns 400 if subdomain query param is absent or empty
- Network/server error — returns 5xx if StableEmail backend is unavailable
