n8n-nodes-deapi


This is an n8n community node that lets you use deAPI in your n8n workflows.

deAPI is a unified API platform providing instant access to open-source AI models (FLUX, LTX Video, Whisper and more) through a decentralized GPU network. One API key to access thousands of GPUs with up to 20x lower costs.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

How It Works

Generation operations (image, video, transcription) use a webhook-based waiting pattern:

1. The node submits a generation request to deAPI with a webhook URL
2. The workflow pauses while deAPI processes the request
3. When deAPI completes the job, it sends a webhook notification
4. The workflow resumes with the generated content (binary file or text)

This approach ensures efficient resource usage – the workflow doesn’t actively poll for results.

Compatibility

• Tested with n8n version 2.3.4
• Webhook-based operations require n8n to be accessible via HTTPS

Example Workflow

An example n8n workflow demonstrating all available operations is included in guide.json”>deAPIguide.json from the GitHub repository
2. In n8n, go to Workflows > Import from File
3. Select the downloaded deAPI_guide.json
4. Set up your deAPI credentials (API Key + Webhook Secret)
5. Explore the example nodes and sticky notes for usage instructions
