Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

n8n community node for deAPI - AI image generation, video generation, transcription and prompt optimization

Readme

n8n-nodes-deapi

npm version License: MIT

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.

Credentials

To use this node, you need to configure the following credentials:

| Field | Description | |-------|-------------| | API Key | Your deAPI API key. Get it from the deAPI Quickstart Guide. | | Webhook Secret | Secret used to verify webhook signatures. Configure it at deAPI Webhook Settings. |

Operations

Image

| Operation | Description | Models | |-----------|-------------|--------| | Generate | Generate an image from a text prompt | FLUX.1 Schnell, FLUX.2 Klein 4B, Z-Image Turbo | | Remove Background | Remove the background from an image | Ben2 | | Upscale | Increase image resolution by 4x | RealESRGAN x4 |

Video

| Operation | Description | Models | |-----------|-------------|--------| | Generate | Generate a video from text or image(s) | LTX-Video 0.9.8, LTX-2 19B | | Transcribe | Transcribe video to text (YouTube, Twitch, X, Kick URLs or file upload) | Whisper Large V3 |

Audio

| Operation | Description | Models | |-----------|-------------|--------| | Transcribe | Transcribe audio file to text | Whisper Large V3 |

Prompt

| Operation | Description | |-----------|-------------| | Image Prompt Booster | Optimize a prompt for text-to-image generation | | Video Prompt Booster | Optimize a prompt for text/image-to-video generation |

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 examples/deAPI_guide.json. Import it into your n8n instance to get started quickly:

  1. Download deAPI_guide.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
