EvoLink Cheapest Image

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

Run

Try Python first (zero dependencies, all platforms):

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.
