Technical Specifications of mj-fast-upload

What is mj-fast-upload?

mj-fast-upload is a CometAPI-exposed Midjourney model endpoint intended for fast image-generation task submission in a Midjourney-style workflow. Based on CometAPI’s model listing and Midjourney quick-start documentation, it is designed for developers who want to trigger image generation through a unified API rather than interacting with Midjourney manually.

While CometAPI’s public model page gives only a brief description, the surrounding documentation shows that Midjourney integrations on the platform use an asynchronous task pattern: you send a request, receive task metadata, and then retrieve output details and any available follow-up actions from the API response. That makes mj-fast-upload suitable for apps that need automated image generation pipelines, creative tooling, internal dashboards, or production workflows that depend on programmatic image creation.

Main features of mj-fast-upload

• Fast task submission: The model is positioned as a fast-upload Midjourney endpoint, indicating an optimized path for sending generation jobs into a Midjourney-compatible API workflow.
• Midjourney-style image generation: It is part of CometAPI’s Midjourney model lineup and is intended for prompt-based image creation through API calls rather than a manual UI flow.
• Asynchronous workflow support: CometAPI’s Midjourney quick-start shows a submit-then-retrieve pattern, which is important for apps that need queue handling, background jobs, or task-state tracking.
• Follow-up action compatibility: The documentation notes that button labels and custom IDs can vary by Midjourney version, implying support for downstream actions such as post-generation operations driven by API response metadata.
• Commercial usage availability: The CometAPI listing explicitly marks the model as available for commercial use.
• Low per-request pricing: CometAPI lists mj-fast-upload at $0.008 per request, which makes it straightforward to estimate costs for batch or production usage.
• Unified platform integration: Because it is listed in CometAPI’s catalog, developers can access it through the platform’s standardized authentication and API workflow instead of building a separate provider-specific integration.

How to access and integrate mj-fast-upload

Step 1: Sign Up for API Key

Sign up on CometAPI and create an API key from your dashboard. Once your account is ready, you can use the same credential structure used across CometAPI’s unified API platform to authenticate requests for mj-fast-upload. CometAPI exposes this model in its model catalog, and the Midjourney quick-start documentation provides the API workflow reference you can use during implementation.

Step 2: Send Requests to mj-fast-upload API

Use CometAPI's Midjourney-compatible endpoint at POST /mj/submit/upload-discord-images.

curl https://api.cometapi.com/mj/submit/upload-discord-images \
  -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.
