Troubleshooting

"KIE_API_KEY not set"

Add to ~/.openclaw/openclaw.json:

"env": {
  "vars": {
    "KIE_API_KEY": "your-key-here"
  }
}

"Credits insufficient"

Top up at: https://kie.ai/billing

"MATON_API_KEY not set" (Drive upload)

1. Sign up at https://maton.ai
2. Add MATON_API_KEY to openclaw.json
3. Create Google Drive connection at https://ctrl.maton.ai

"Drive upload failed"

1. Check MATON_API_KEY is set
2. Verify Google Drive connection is active at https://ctrl.maton.ai
3. Ensure folder_id in config.json is correct
4. Try generating without --upload-drive first

Integration with OpenClaw

Use via exec or directly in OpenClaw agent conversations:

# From OpenClaw chat
Generate a cyberpunk city image with kie.ai

# The agent will run:
cd ~/src/kie-ai-skill && ./kie-ai.sh generate-image "cyberpunk city"

Security

Environment Variables

External Endpoints

Data Leaving This Machine

• Prompt text is sent to api.kie.ai to generate images.
• Generated image files are sent to gateway.maton.ai only when --upload-drive is explicitly passed.
• API keys are transmitted as Authorization: Bearer headers and are never logged or written to disk by this skill.
• No telemetry, analytics, or usage data is collected by this skill itself.

Trust Statement

This skill sends data to two third-party services: kie.ai for AI generation and maton.ai as an OAuth gateway for Google Drive. Review their respective privacy policies before use. Drive upload is strictly opt-in via --upload-drive.

Autonomous Invocation

This skill can be invoked autonomously by an OpenClaw agent when asked to generate images. It does not execute autonomously on its own — it must be called explicitly. To prevent autonomous invocation, remove the skill symlink from your OpenClaw workspace.
