ComfyUI API Key on OpenClaw: Enable Cloud Music & Video Workflows

What Is ComfyUI?

ComfyUI is an open-source, node-based interface for building custom AI image, video, and music generation pipelines. Originally a local desktop application, platform.comfy.org is the official cloud platform that lets you run your ComfyUI workflows via API without managing your own GPU hardware. Workflows are JSON graphs that chain together models, samplers, and post-processing steps — giving you far more control than simple prompt-to-image APIs.

On OpenClaw Launch, the ComfyUI integration routes calls to the platform.comfy.org cloud API using your personal key. You bring the key; we handle authentication, routing, and applying it to your running instances instantly.

What Your ComfyUI Key Unlocks

Adding a ComfyUI key enables the comfy/workflow model route on your OpenClaw instances, which covers:

• Music workflows — Generate original music tracks and audio using ComfyUI music pipeline workflows hosted on the ComfyUI cloud
• Video workflows — Run text-to-video and image-to-video ComfyUI workflow graphs on cloud GPUs via the comfy/workflow route
• Custom workflow execution — Any ComfyUI-compatible workflow JSON you upload runs on platform.comfy.org infrastructure at pay-as-you-go rates

ComfyUI cloud is a pay-as-you-go service — you are billed for compute time consumed by each workflow run, not a flat monthly fee.

How to Get a ComfyUI API Key

1. Go to platform.comfy.org — Open platform.comfy.org/login and sign in or create a new account.
2. Navigate to API Keys — After signing in, open your account settings or the API section in the dashboard. Look for “API Keys” or “Credentials” in the sidebar.
3. Create a new key — Click “Create API Key” (or similar). Give it a descriptive name such as “OpenClaw Launch” so you can identify it later.
4. Copy your key — Your ComfyUI API key starts with comfy-. Copy it immediately — most platforms only show the full key once.
5. Add billing credits — ComfyUI cloud is pay-as-you-go. Add credits to your account so workflow runs are not blocked when you start generating.

Add It on OpenClaw Launch

1. Sign in at openclawlaunch.com and open the API Keys page.
2. Find the ComfyUI card. Paste your comfy-... key into the input field and click Save. OpenClaw Launch validates the key live against the ComfyUI API before storing it.
3. Your key is stored encrypted at rest and is applied to all your existing running instances immediately — no redeploy needed.
4. To use ComfyUI workflows, open your instance’s settings and select the desired music or video model from the media settings panel. ComfyUI workflow models will appear once your key is saved.

Troubleshooting

401 Unauthorized / Invalid Key

• Verify your key starts with comfy- — keys from the wrong section of the dashboard (e.g. a workspace token vs. an API key) may have a different format
• Check for accidental trailing whitespace when copying — paste into a plain text editor first to inspect
• Make sure you created the key under the correct account; if you belong to multiple ComfyUI organizations, the key must match the billing account you funded

Workflow Not Found / Model Route Missing

• The comfy/workflow route only appears after a valid ComfyUI key is saved — confirm the key saved successfully on the API Keys page (it will show a green checkmark)
• If the model selector still shows no ComfyUI options after saving, try refreshing your instance settings page

Quota / Insufficient Credits

• ComfyUI cloud is pay-as-you-go — if your platform.comfy.org account has no credits, workflow runs fail with a billing error. Add credits at platform.comfy.org
• Long video workflows consume more credits than short music clips — check your usage in the ComfyUI dashboard if you run out unexpectedly

Frequently Asked Questions

Is ComfyUI cloud free?

No. platform.comfy.org is a pay-as-you-go cloud service. You pay for the GPU compute time each workflow run uses. There is no free tier listed in our fact sheet — you need to add credits to your account before running workflows.

What is the key prefix for ComfyUI?

ComfyUI API keys start with comfy-. If your key does not start with this prefix, you may have copied a session token or workspace token instead. Return to the API Keys section of your platform.comfy.org account to generate a proper API key.

Does adding a ComfyUI key affect my running OpenClaw instances?

Yes, in a good way. Once you save the key on the API Keys page, it is applied to all your existing running instances instantly. You do not need to stop, redeploy, or reconfigure anything — the ComfyUI workflow models just appear in your instance media settings.

Can I use ComfyUI alongside other media providers like fal?

Yes. You can have multiple media provider keys saved simultaneously. Each model card in your instance settings shows which provider it routes through, so you can mix fal image models with ComfyUI music workflows and Runway video models on the same instance.
