Quick Start — Generate an Image

curl -X POST https://api.acedata.cloud/midjourney/imagine \
  -H "Authorization: Bearer $ACEDATACLOUD_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "a futuristic city at sunset, cyberpunk style --ar 16:9", "wait": true}'

Midjourney Versions

Core Workflows

1. Generate Images (Imagine)

Creates a 2x2 grid of 4 image variations.

POST /midjourney/imagine
{
  "prompt": "a serene mountain lake at dawn, photorealistic --ar 16:9 --v 7",
  "mode": "fast",
  "translation": true,
  "split_images": true
}

Set translation: true to auto-translate non-English prompts. Set split_images: true to get individual images besides the grid.

2. Upscale / Vary / Pan / Zoom

After generating a grid, use transform actions on individual images:

POST /midjourney/imagine
{
  "action": "upscale1",
  "image_id": "grid-image-id"
}

Available actions:

• upscale1–upscale4: Upscale individual quadrant
• variation1–variation4: Create variation of a quadrant
• variation_subtle / variation_strong: Subtle/strong variation of full image
• reroll: Re-generate with same prompt
• zoom_out_2x / zoom_out_1_5x: Zoom out
• pan_left / pan_right / pan_up / pan_down: Extend canvas

3. Edit an Image

Modify an existing image using a text prompt, optionally with a mask.

POST /midjourney/edits
{
  "image_url": "https://example.com/photo.jpg",
  "prompt": "add a rainbow in the sky",
  "mode": "fast"
}

4. Blend Images

Combine 2–5 images into a new composition.

POST /midjourney/imagine
{
  "action": "blend",
  "image_urls": [
    "https://example.com/image1.jpg",
    "https://example.com/image2.jpg"
  ]
}

5. Describe an Image (Reverse Prompt)

Get AI-generated text descriptions of an image (returns 4 options).

POST /midjourney/describe
{"image_url": "https://example.com/photo.jpg"}

6. Generate Video from Image

Create a video with a reference image and text prompt.

POST /midjourney/videos
{
  "image_url": "https://example.com/photo.jpg",
  "prompt": "the city comes alive with moving traffic",
  "resolution": "720p"
}

Prompt Parameters

Append these to your prompt text:

Gotchas

• Imagine returns a 2x2 grid — use upscale/variation actions to work with individual images
• Use split_images: true to also receive individual cropped images alongside the grid
• Prompt parameters (--ar, --v, etc.) go inside the prompt string, not as separate fields
• translation: true auto-translates Chinese/other languages to English before sending to Midjourney
• Video generation requires a reference image_url — it cannot generate from text alone
• Available transform actions depend on the image — check available_actions in the response
• Get the seed with POST /midjourney/seed using the image_id for reproducible results
