# ezhst domains add

Add a custom domain to an app.

## Usage

```
ezhst domains add <hostname>
```

Create the DNS record next, then verify.

## In scripts and agents

Add `--json` to read the result from stdout. Progress goes to stderr. On failure the process exits with code 1 and prints `{"error": "..."}`. Without a TTY the CLI never prompts, so pass every value as a flag.

```
npx ezhst domains add --json
```
