Technical Specifications of mj-fast-custom-zoom

What is mj-fast-custom-zoom?

mj-fast-custom-zoom is CometAPI’s platform identifier for a Midjourney-based custom zoom workflow. Based on Midjourney’s official Zoom Out documentation, this type of model takes an already generated image and creates a new version that appears “pulled back,” revealing more of the surrounding scene without simply resizing the original pixels. Instead, it generates new visual content around the existing composition to widen the image’s apparent field of view.

In practical terms, this makes mj-fast-custom-zoom useful when you already like a generated image but want to extend the scene, add environmental context, or create a more cinematic composition. Midjourney’s documented custom zoom controls allow values between 1.0 and 2.0, giving users more control than fixed preset zoom levels such as 1.5x or 2x.

Because CometAPI exposes this capability as an API-accessible model entry, developers can integrate custom zoom expansion into creative tools, automated design pipelines, image iteration systems, and content production workflows that need fast access to Midjourney-style image expansion. This description is an inference based on CometAPI’s model listing plus Midjourney’s documented Zoom Out behavior.

Main features of mj-fast-custom-zoom

• Custom zoom-out control: Supports the Midjourney-style custom zoom concept, letting users expand an image beyond fixed presets and control the apparent pull-back amount within the documented 1.0–2.0 range.
• Scene expansion instead of simple resize: The workflow does not merely scale the original image; it generates new surrounding content so the final result feels like a wider shot of the same scene.
• Preserves central composition: Midjourney’s zoom-out behavior keeps the original image visually centered while adding new detail around it, which is valuable for iterative design and storytelling continuity.
• Prompt-adjustable creative editing: Midjourney documents that users can combine zooming with prompt changes and editor-based controls, making this workflow useful for guided scene evolution rather than one-click resizing alone.
• Fits image editing pipelines: The model is listed by CometAPI in its image model catalog, indicating it is intended for programmatic access inside application workflows and production systems.
• Commercially usable via CometAPI: CometAPI’s listing marks the model as available for commercial use, which is helpful for business and product integrations.
• Fast API-oriented deployment path: API ecosystems for Midjourney-style generation commonly use authenticated task submission and polling patterns, making this model suitable for asynchronous app integration where requests are submitted and results are retrieved later.

How to access and integrate mj-fast-custom-zoom

Step 1: Sign Up for API Key

Sign up on CometAPI and create your API key from the dashboard. Store the key securely and use it for all authenticated requests to the mj-fast-custom-zoom API.

Step 2: Send Requests to mj-fast-custom-zoom API

Use CometAPI's Midjourney-compatible endpoint at POST /mj/submit/action.

curl https://api.cometapi.com/mj/submit/action \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $COMETAPI_API_KEY" \
  -d '{
    "prompt": "a futuristic cityscape at sunset --v 6.1",
    "botType": "MID_JOURNEY",
    "accountFilter": {
      "modes": ["FAST"]
    }
  }'

Step 3: Retrieve and Verify Results

The API returns a task object with a task ID. Poll GET /mj/task/{task_id}/fetch to check generation status and retrieve the output image URL when the task reaches a terminal state.
