```

**Configure credentials**:

## Article draft

Convert Markdown to WeChat article:

```bash
md2wx article-draft --file article.md --theme bytedance --cover-image "https://cdn.example.com/cover.jpg"
```

Or pass inline Markdown:
```bash
md2wx article-draft --markdown "# Title\n\nContent" --theme elegant-red --cover-image "https://cdn.example.com/cover.jpg"
```

Note:
- `article-draft` does not read from stdin pipe directly.
- For API compatibility, always provide `--cover-image` with a public URL.

## Newspic draft

Create image-rich card drafts:

```bash
md2wx newspic-draft --title "标题" --content "内容" --images "https://cdn.example.com/img1.jpg,https://cdn.example.com/img2.png"
```

## Batch upload

Upload images and get WeChat CDN URLs:

```bash
md2wx batch-upload --images "https://cdn.example.com/a.jpg,https://cdn.example.com/b.jpg"
```

Image input constraints:
- API accepts public image URLs only.
- Local file paths and glob patterns are not supported.
