Cheapest Image Generation

# 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.
