Example Workflows

This extension includes several example workflows in the workflows folder:

• basic_pixeldojo.json: Simple workflow demonstrating basic image generation
• advanced_pixeldojo.json: Workflow showing integration with upscaling nodes
• lora_pixeldojo.json: Example of using LoRA models with PixelDojo

To use an example workflow:

Credit Usage

Each image generated by the PixelDojo API uses credits from your PixelDojo account:

You must have an active subscription and sufficient credits to use the API.

Notes on Image Storage

Images generated through the API are stored temporarily on PixelDojo servers for 24 hours. When you save images through ComfyUI, they are saved locally on your computer.
