RunningHub CLI (rh) — Agent Skill

What This Tool Does

rh is a command-line interface for the RunningHub AI platform — a cloud ComfyUI service with 209+ built-in AI model endpoints and support for custom ComfyUI workflow apps.

Use rh to:

• Generate images, videos, audio, and 3D models from text/image prompts
• Browse and run custom ComfyUI AI App workflows
• Check task status and download outputs
• Monitor account balance

Setup

export RH_API_KEY=your_runninghub_api_key

Or pass --api-key KEY to any command.

Built-in Models (rh model)

For quick AI generation using RunningHub's 209 pre-built models.

# List available models
rh model list --type image
rh model list --task text-to-image --top 5
rh model list --type video

# Get parameter schema for an endpoint
rh model info rhart-image-n-pro/text-to-image

# Auto-select best model for a task (recommended for agents)
rh model auto --task text-to-image --prompt "a sunset over mountains" --output out.png
rh model auto --task image-to-video --image input.jpg --output out.mp4
rh model auto --task text-to-speech --prompt "Hello world" --output out.mp3
rh model auto --task text-to-3d --prompt "a ceramic teapot" --output model.glb

# Run a specific endpoint
rh model run rhart-image-n-pro/text-to-image --prompt "anime cat" --output cat.png
rh model run kling-video-o3-pro/image-to-video --image photo.jpg --output video.mp4

Available task types:

• text-to-image, image-to-image, image-upscale
• text-to-video, image-to-video, reference-to-video, start-end-to-video
• text-to-speech, music-generation, voice-clone
• text-to-3d, image-to-3d, multi-image-to-3d

Custom AI Apps (rh app)

For custom ComfyUI workflows. Each app has a webappId and modifiable input nodes.

# Browse public apps
rh app list --search "anime portrait" --sort RECOMMEND
rh app list --sort HOTTEST --size 10

# Inspect an app's input schema before running
rh app info 1234567890
# → {"webappId": "...", "name": "...", "nodes": [{"nodeId": "6", "fieldName": "prompt", "fieldType": "STRING", ...}]}

# Run an app
rh app run 1234567890 \
  --node "6:prompt=a samurai cat warrior" \
  --output result.mp4

# Run with a file input
rh app run 1234567890 \
  --node "6:prompt=enhance this portrait" \
  --file "10:image=/path/to/photo.jpg" \
  --output enhanced.png

# Batch run from CSV
rh app batch 1234567890 --input params.csv --concurrency 3 --output-dir ./results/

Batch CSV format:

6:prompt,10:image
"a ninja dog",/path/to/dog.jpg
"a robot cat",/path/to/cat.jpg

Task Management

# Check status of a task
rh task status abc123

# Get outputs for a completed task
rh task outputs abc123 --output result.png

JSON Output Schema

All commands output JSON. Agents should parse stdout directly.

rh model auto / rh model run success:

{
  "taskId": "abc123",
  "status": "SUCCESS",
  "outputs": [{"fileUrl": "https://cdn.runninghub.cn/...", "fileType": "image/png"}],
  "cost": {"duration_s": 8},
  "savedTo": "/path/to/out.png",
  "selectedEndpoint": "rhart-image-n-pro/text-to-image"
}

rh app run success:

{
  "taskId": "xyz789",
  "status": "SUCCESS",
  "outputs": [{"fileUrl": "https://...", "fileType": "video/mp4"}],
  "savedTo": "/path/to/result.mp4"
}

Errors (exit code 1):

{"error": "auth_failed", "message": "Invalid API key or unauthorized"}
{"error": "insufficient_balance", "message": "Account balance is 0"}
{"error": "task_failed", "message": "Task failed: ..."}
{"error": "timeout", "message": "Task exceeded 20 minute timeout"}

Typical Agent Workflows

1. Generate an image

rh model auto --task text-to-image --prompt "a photorealistic sunset over the ocean" --output sunset.png

2. Generate a video from an image

rh model auto --task image-to-video --image portrait.jpg --output animation.mp4

3. Discover and run a custom ComfyUI app

# Step 1: find apps
rh app list --search "anime portrait" --size 5

# Step 2: check the app's inputs
rh app info <webappId>

# Step 3: run it
rh app run <webappId> --node "6:prompt=anime warrior" --file "10:image=photo.jpg" --output result.png

4. Check balance before running

rh account status | python3 -c "import sys,json; d=json.load(sys.stdin); print(d['remainCoins'])"

Error Handling

• All errors produce JSON with an error key and exit code 1
• Progress is written to stderr (polling dots); final JSON is on stdout
• Separate stderr from stdout: rh model auto ... 2>/dev/null

Notes

• Tasks may take 5 seconds to 20 minutes depending on the model
• Video generation is slower than image generation
• The --instance plus flag (for rh app run) uses premium compute
