Black Forest Labs API Nodes for ComfyUI

This setup allows you to integrate and access BFL's API directly from within your ComfyUI workflow.

Installation Instructions

Step 1: Add `bfl_api.py` to Your ComfyUI Environment

Clone this repo in your ComfyUI/custom_nodes directory.

Step 2: Set Up Your BFL API Key

To authenticate your requests, you need to provide your BFL API key from the Black Forest Labs API.

There are two ways to provide your key to ComfyUI:
1. Environment Variable Method (Recommended)
  - Export your BFL API key as an environment variable:
```
export BFL_API_KEY=<your_api_key_here>
```
2. Text File Method
  - Alternatively, insert your API key into a file named bfl_api_key.txt.
  - Ensure that the bfl_api_key.txt file is placed in the same directory as bfl_api.py.

Step 3: Restart ComfyUI

Restart ComfyUI if already open

Step 4: Insert a FLUX API Node into Your Workflow

Troubleshooting

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