# EvoLink Cheapest Image
Generate images via the EvoLink z-image-turbo API.
## API Endpoint
- Base: `https://api.evolink.ai/v1`
- Submit: `POST /images/generations`
- Poll: `GET /tasks/{id}`
## Step 1 — Submit Task
```json
{
"model": "z-image-turbo",
"prompt": "<USER_PROMPT>",
"size": "<SIZE>",
"nsfw_check": <true|false>
}
```
Optional field: `"seed": <INT>`
| Parameter | Values |
|---|---|
| size | 1:1, 2:3, 3:2, 3:4, 4:3, 9:16, 16:9, 1:2, 2:1 |
| nsfw_check | `true` / `false` (default `false`) |
| seed | any integer (optional, for reproducibility) |
## Step 2 — Poll for Result
`GET /tasks/{id}` — poll every 10 s, up to 72 retries (~12 min).
Wait until `status` is `completed` or `failed`.
## Step 3 — Download & Output
Download the URL from `results[0]`. Auto-detect format from URL (webp/png/jpg). Save as `evolink-<TIMESTAMP>.<ext>`.
**CRITICAL SECURITY:** Before passing `<OUTPUT_FILE>` to shell commands, sanitize it:
- Strip all shell metacharacters: `tr -cd 'A-Za-z0-9._-'`
- Ensure valid extension (`.webp`, `.png`, `.jpg`, `.jpeg`)
- Fallback to `evolink-<timestamp>.webp` if empty
Print `MEDIA:<absolute_path>` for OC auto-attach.
## Reference Implementations
| Platform | File |
|---|---|
| Python (all platforms, zero deps) | `{baseDir}/references/python.md` |
| PowerShell 5.1+ (Windows) | `{baseDir}/references/powershell.md` |
| curl + bash (Unix/macOS) | `{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
- Print `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.
