Configuration

Step 1: Get Your API Key

Go to sequencer.media and sign in
Navigate to Settings → API Keys
Click Create API Key and copy it (you won't see it again!)

Step 2: Get Your Workspace ID

In the Sequencer web app, go to the Dashboard → Images (or Vidoes)
Look at the URL - it contains your workspace ID after /workspace/
Or create a new workspace in the Sequencer web app

Step 3: Save Your Config

Create the config file at ~/.sequencer/config.json:

{
  "api_key": "sk_your_api_key_here",
  "workspace_id": "your_workspace_id_here"
}

Linux/macOS:

mkdir -p ~/.sequencer
echo '{"api_key": "sk_YOUR_KEY", "workspace_id": "YOUR_WORKSPACE_ID"}' > ~/.sequencer/config.json
chmod 600 ~/.sequencer/config.json

Windows (PowerShell):

New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.sequencer"
Set-Content "$env:USERPROFILE\.sequencer\config.json" '{"api_key": "sk_YOUR_KEY", "workspace_id": "YOUR_WORKSPACE_ID"}'

Alternative: Environment Variables

export SEQUENCER_API_KEY="sk_your_api_key_here"
export SEQUENCER_WORKSPACE_ID="your_workspace_id_here"

Troubleshooting

"No Sequencer API key configured"

Create ~/.sequencer/config.json with your API key. See Configuration.

"No models loaded"

Check your internet connection
Verify your API key is valid at sequencer.media/settings
Restart ComfyUI to refresh the model registry

"Insufficient credits"

Top up your balance at sequencer.media.

"Generation timed out"

Some models (especially video) can take 1-3 minutes. If the timeout persists, check the Sequencer dashboard for status.

Ensure the folder is named sequencer-comfy-nodes and placed directly inside ComfyUI/custom_nodes/. Restart ComfyUI completely.
