ImaginePro AI Image Generation API

Generate stunning AI images, videos, and edits using the ImaginePro API. This skill wraps the full ImaginePro backend and supports 5 generation models, image upscaling, background removal, prompt enhancement, and video generation.

Quick Start

# Set your API key (get one at https://platform.imaginepro.ai/dashboard/setup)

API Reference

Image Generation

POST /midjourney/imagine — Midjourney Generation

The flagship model. Supports Midjourney parameters in the prompt string (e.g., --ar 16:9, --style raw, --relax).

  "ref": "optional-tracking-id",
  "webhookOverride": "https://your-server.com/webhook"
}

• Append --relax to the prompt for relax mode (5 credits instead of 10, slower).
• Supports all standard Midjourney prompt parameters: --ar, --style, --chaos, --no, --seed, --q, etc.

Response:

{
  "success": true,
  "messageId": "uuid-of-the-generation-task",

Async Workflow

All generation endpoints are asynchronous. The workflow is:

1. Submit a generation request → receive a messageId
2. Poll GET /midjourney/message/{messageId} every 3-5 seconds
3. Wait for status to be DONE (images ready) or FAIL (error)
4. Download the result from the uri or images array

The helper script's wait command automates this entire flow.

Python Helper Script

The included imaginepro_api.py is a zero-dependency Python script (stdlib only) that wraps all API calls.

Commands

# Generate an image (async — returns messageId immediately)
python3 imaginepro_api.py imagine --prompt "a sunset over mountains" --model flux

# Generate and wait for result (blocking — polls until done)
python3 imaginepro_api.py wait --prompt "a sunset over mountains" --model flux

# Check status of a generation
python3 imaginepro_api.py status --id <messageId>

# Upscale (Midjourney)
python3 imaginepro_api.py upscale --id <messageId> --button U1

# Upscale (Flux)
python3 imaginepro_api.py upscale --image "https://example.com/img.jpg" --scale 2

# Remove background
python3 imaginepro_api.py removebg --image "https://example.com/photo.jpg"

# Enhance a prompt
python3 imaginepro_api.py enhance --prompt "a cat"

# List available models
python3 imaginepro_api.py models

Flags

• --json — Output raw JSON (default is human-readable)
• --timeout <seconds> — Max wait time for wait command (default: 300)
• --interval <seconds> — Polling interval for wait command (default: 5)

curl Examples

# Generate with Flux
curl -X POST https://api.imaginepro.ai/api/v1/flux/imagine \
  -H "Authorization: Bearer $IMAGINEPRO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "a cyberpunk cityscape at sunset"}'

# Check status
curl https://api.imaginepro.ai/api/v1/midjourney/message/<messageId> \
  -H "Authorization: Bearer $IMAGINEPRO_API_KEY"

# Enhance a prompt (free)
curl -X POST https://api.imaginepro.ai/api/v1/tools/prompt-extend \
  -H "Authorization: Bearer $IMAGINEPRO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "a cat"}'

Error Handling

API errors return JSON with message, error, and statusCode:

{
  "message": "Prompt is required.",
  "error": "Bad Request",
  "statusCode": 400
}

Common error codes:

• 400 — Missing required parameter or invalid value
• 401 — Invalid or missing API key / insufficient credits
• 404 — Message not found
• 500 — Internal server error (retry after a short delay)

Tips for AI Agents

1. Always use the wait command for simple generation tasks — it handles the submit + poll loop automatically.
2. Check credits on the dashboard at https://platform.imaginepro.ai/dashboard before large batches to avoid failures mid-way through. There is no API endpoint for checking credits.
3. Use enhance on short prompts before generating — it's free and dramatically improves quality.
4. Midjourney supports prompt parameters like --ar 16:9 --style raw --chaos 20 directly in the prompt string.
5. For Nano Banana (virtual try-on, mockups), always provide reference image URLs in the contents array.
6. Poll interval: 5 seconds is recommended. Don't poll faster than 3 seconds.
7. Timeouts: Midjourney can take 30-120s. Video generation can take up to 15 minutes. Set timeouts accordingly.
