| Method | Path pattern | Description |
| --- | --- | --- |
| `get` | `/status/...` | Return admin-only Let's Encrypt status from `mod_ssl_letsencrypt:status/1` (certificate/renewal state for this site). |

`/+name` marks a variable path segment. A trailing `/...` means extra path segments are accepted for further lookups.
