ImageRouter Image Generation

Generate images with any model available on ImageRouter using curl commands.

Available models

The test/test model is a free dummy model that is used for testing the API. It is not a real model, therefore you should use other models for image generation.

Get top 10 most popular models:

curl -X POST 'https://backend.imagerouter.io/operations/get-popular-models'

Search available models by name:

curl "https://api.imagerouter.io/v1/models?type=image&sort=date&name=gemini"

Get all available models:

curl "https://api.imagerouter.io/v1/models?type=image&sort=date&limit=1000"

Quick Start - Text-to-Image

Basic generation with JSON endpoint:

curl 'https://api.imagerouter.io/v1/openai/images/generations' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  --json '{
    "prompt": "a serene mountain landscape at sunset",
    "model": "test/test",
    "quality": "auto",
    "size": "auto",
    "response_format": "url",
    "output_format": "webp"
  }'

Unified Endpoint (Text-to-Image & Image-to-Image)

Text-to-Image with multipart/form-data:

curl 'https://api.imagerouter.io/v1/openai/images/edits' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -F 'prompt=a cyberpunk city at night' \
  -F 'model=test/test' \
  -F 'quality=high' \
  -F 'size=1024x1024' \
  -F 'response_format=url' \
  -F 'output_format=webp'

Image-to-Image (with input images):

curl 'https://api.imagerouter.io/v1/openai/images/edits' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -F 'prompt=transform this into a watercolor painting' \
  -F 'model=test/test' \
  -F 'quality=auto' \
  -F 'size=auto' \
  -F 'response_format=url' \
  -F 'output_format=webp' \
  -F 'image[]=@/path/to/your/image.webp'

Multiple images (up to 16):

curl 'https://api.imagerouter.io/v1/openai/images/edits' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -F 'prompt=combine these images' \
  -F 'model=test/test' \
  -F 'image[][email protected]' \
  -F 'image[][email protected]' \
  -F 'image[][email protected]'

With mask (some models require mask for inpainting):

curl 'https://api.imagerouter.io/v1/openai/images/edits' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -F 'prompt=fill the masked area with flowers' \
  -F 'model=test/test' \
  -F 'image[][email protected]' \
  -F 'mask[][email protected]'

Endpoint Comparison

| Feature | Unified (/edits) | JSON (/generations) | |---------|------------------|---------------------| | Text-to-Image | ✅ | ✅ | | Image-to-Image | ✅ | ❌ | | Encoding | multipart/form-data | application/json |

Tips

• Both /v1/openai/images/generations and /v1/openai/images/edits are the same for the unified endpoint
• Use JSON endpoint for simple text-to-image when you don't need file uploads
• Use unified endpoint when you need Image-to-Image capabilities
• Check model features at https://imagerouter.io/models (quality support, edit support, etc.)
• Get your API key at https://imagerouter.io/api-keys
