BlackForestLabs API Nodes for ComfyUI

in

Integrating the BlackForestLabs (BFL) API with ComfyUI unlocks a range of advanced features, allowing you to seamlessly connect to BFL’s robust tools and services directly within your image-generation workflows. With BFL’s API nodes, you can expand the creative and functional potential of ComfyUI by incorporating the power of FLUX and other cutting-edge features into your projects.

ComfyUI, known for its flexibility and modular architecture, is an open-source interface designed for running Stable Diffusion and similar models. Its node-based workflow system makes it highly adaptable for integrating external APIs like BlackForestLabs, enabling users to access advanced features with ease.

Installation Instructions

Setting up BFL API nodes in ComfyUI involves a few straightforward steps:

Step 1: Add the bfl_api.py Node

To get started, download the BFL API script and place it in your ComfyUI environment:

  • Clone the repository containing bfl_api.py into the ComfyUI/custom_nodes directory.

Step 2: Configure Your BFL API Key

Authentication with the BlackForestLabs API requires an API key. You can set up the key using one of two methods:

Environment Variable Method (Recommended):

  1. Export your API key as an environment variable:
    bash export BFL_API_KEY=<your_api_key_here>

Text File Method:

  1. Create a text file named bfl_api_key.txt.
  2. Add your API key to the file.
  3. Place the bfl_api_key.txt file in the same directory as bfl_api.py.

Step 3: Restart ComfyUI

After setting up the API key, restart ComfyUI to load the new nodes.

Step 4: Add a FLUX API Node to Your Workflow

Once ComfyUI restarts, the BFL API nodes will be available in your workflow.

  • Insert a node such as FLUX 1.1 [pro] by dragging and dropping it into your workspace.

Step 5: Start Exploring

With the nodes now active, you can start incorporating BFL’s API functionality into your image-generation pipelines.

Troubleshooting

If you encounter any issues, here are some common solutions:

  • Invalid API Key Error: Double-check that the API key is correctly set in your environment variable or the bfl_api_key.txt file.
  • Node Not Appearing: Ensure bfl_api.py is placed in the ComfyUI/custom_nodes directory and restart ComfyUI.
