🎯 Usage

Basic Workflow

1. Add the Node - Search for "Runpod Public Endpoints" in the nodes panel

2. Select Operation - Choose from:

   • Generate Text - Chat models (Granite, Qwen3, Deep Cogito)
   • Generate Image - Diffusion models (Flux, Qwen Image, Seedream)
   • Generate Video - Video models (WAN, Seedance, Kling, Sora)
   • Generate Audio - Audio models (Whisper, Minimax)
   • Get Status - Check async job status

3. Choose Model - Dropdown automatically shows relevant models

4. Configure Input - Use built-in examples or customize JSON

5. Execute - Run your workflow!

Example Operations

Text Generation

{
  "messages": [
    {
      "role": "system",
      "content": "You are a helpful assistant."
    },
    {
      "role": "user",
      "content": "What is Runpod?"
    }
  ],
  "sampling_params": {
    "max_tokens": 512,
    "temperature": 0.7,
    "seed": -1,
    "top_k": -1,
    "top_p": 1
  }
}

Image Generation

{
  "prompt": "A serene mountain landscape at sunset",
  "negative_prompt": "blurry, low quality",
  "width": 1024,
  "height": 1024,
  "num_inference_steps": 20,
  "guidance": 7.5,
  "seed": 42,
  "image_format": "png"
}

Video Generation

{
  "prompt": "A serene morning in an ancient forest, golden sunlight filtering through tall pine trees",
  "num_inference_steps": 30,
  "guidance": 5,
  "negative_prompt": "",
  "size": "1280*720",
  "duration": 5,
  "flow_shift": 5,
  "seed": -1,
  "enable_prompt_optimization": false,
  "enable_safety_checker": true
}

🔄 Async Operations

For long-running tasks (video generation, complex images), use async mode:

1. Set Wait for Completion to false
2. Execute - Returns a job ID
3. Use Get Status operation to check progress
4. Poll until status is COMPLETED

🚨 Troubleshooting

Common Issues

1. "Runpod API" credential not showing

• Solution: Restart n8n after installing the node
• Check: Verify the node appears in Settings → Community Nodes

2. 401 Authentication Error

• Solution: Verify your API key is correct and starts with rpa_
• Check: Test the credential connection in n8n

3. JSON parsing errors

• Solution: Use the built-in examples or validate JSON syntax
• Check: Ensure no unescaped newlines in string values

4. Job stuck in IN_QUEUE

• Solution: Enable "Wait for Completion" or use async polling
• Check: Some models have longer queue times

5. Model dropdown empty

• Solution: Check internet connection (uses GraphQL API)
• Fallback: Node includes hardcoded models if API fails

Debug Mode

Enable debug logging in n8n to see detailed error messages:

N8N_LOG_LEVEL=debug n8n start
