# EvoLink Cheapest Image

Generate images via the EvoLink z-image-turbo API.

## Run

Try Python first (zero dependencies, all platforms):

```bash
python3 {baseDir}/scripts/generate.py --prompt "a cute cat" --size "1:1"
```

Options: `--size` (1:1, 2:3, 3:2, 3:4, 4:3, 9:16, 16:9, 1:2, 2:1), `--seed INT`, `--nsfw-check true`

If Python is unavailable:

- **Windows**: see PowerShell fallback in `{baseDir}/references/powershell.md`
- **Unix/macOS**: use the curl fallback in `{baseDir}/references/curl_heredoc.md`

## API key

- `EVOLINK_API_KEY` env var (required)
- Get key: https://evolink.ai

## Triggers

- Chinese: "生图：xxx" / "出图：xxx" / "生成图片：xxx"
- English: "generate image: xxx" / "generate a picture: xxx"

Treat the text after the colon as `prompt`, use default size `1:1`, generate immediately.

## Notes

- Script prints `MEDIA:<path>` for OC auto-attach — no extra delivery logic needed.
- Image saved locally (format auto-detected from URL). URL expires ~24h but local file persists.
