### Create output directory

Source: https://meituhub.com/docs?f_id=1&id=48

Creates the output directory for downloaded files. On Windows, use 'New-Item -ItemType Directory -Force .\output' instead.

```bash
mkdir -p ./output
```

--------------------------------

### Configure Access Key and Secret Key locally

Source: https://meituhub.com/docs?f_id=1&id=150

Sets the Access Key and Secret Key in the local configuration file. Replace <ACCESS_KEY> and <SECRET_KEY> with your actual keys from MeituHub.

```bash
meitu config set-ak --value <ACCESS_KEY>
meitu config set-sk --value <SECRET_KEY>
```

--------------------------------

### Generate an image with text-to-image

Source: https://meituhub.com/docs?f_id=1&id=150

Creates an output directory and runs the text-to-image command with a prompt, size 2K, JSON output, and download directory. Success is indicated by an image file in the output directory and JSON containing 'code: 0' or 'ok: true'.

```bash
mkdir -p ./output
meitu text-to-image \
  --prompt "a simple illustration of an orange cat" \
  --size 2K \
  --json \
  --download-dir ./output
```

--------------------------------

### Sync command metadata

Source: https://meituhub.com/docs?f_id=1&id=150

```bash
meitu tools update
```

--------------------------------

### Run text-to-image command

Source: https://meituhub.com/docs?f_id=1&id=48

Generates an image from a text prompt. On success, an image file appears under 'output' and the JSON shows 'code: 0' or 'ok: true'.

```bash
meitu text-to-image \
  --prompt "An orange cat, minimalist flat illustration" \
  --size 2K \
  --json \
  --download-dir ./output
```

--------------------------------

### Create output directory on Windows PowerShell

Source: https://meituhub.com/docs?f_id=1&id=48

```powershell
New-Item -ItemType Directory -Force .\output
```

--------------------------------

### Set credentials via environment variables

Source: https://meituhub.com/docs?f_id=1&id=150

Sets the Access Key and Secret Key as environment variables. These take priority over the local config file and are useful for CI/agent environments.

```bash
export MEITU_OPENAPI_ACCESS_KEY="<ACCESS_KEY>"
export MEITU_OPENAPI_SECRET_KEY="<SECRET_KEY>"
```

--------------------------------

### Verify credentials with meitu auth verify

Source: https://meituhub.com/docs?f_id=1&id=150

Checks if the configured credentials are valid. A result of 'code: 0' or 'ok: true' indicates success. If it fails, ensure the keys were copied in full without leading or trailing spaces.
