ClawHub Integration

ClawHub (clawhub.ai) is the skill registry for OpenClaw agents — like npm but for AI agent skills.

Base URL

https://clawhub.ai/api/v1

Authentication

• Token format: clh_<token> as Bearer token
• Generate token: Login at clawhub.ai → Settings → API Tokens
• Store in env: CLAWHUB_TOKEN=clh_xxx
• Validate: GET /api/v1/whoami

curl -H "Authorization: Bearer $CLAWHUB_TOKEN" https://clawhub.ai/api/v1/whoami

Security Considerations

When working with API tokens, especially in automated environments or with AI agents, be aware of the following security considerations:

1. Token Storage: Never store tokens directly in scripts or commands. Use environment variables or secure credential storage.

2. Secure Token Usage:

# Read token from secure file or environment variable
TOKEN=$(cat ~/.secure/clawhub_token)
curl -H "Authorization: Bearer $TOKEN" https://clawhub.ai/api/v1/whoami

# Or use environment variable
curl -H "Authorization: Bearer $CLAWHUB_TOKEN" https://clawhub.ai/api/v1/whoami

3. Security Scanning: Many environments now scan for exposed credentials. If you encounter security warnings:

   • Do not bypass security checks
   • Use proper credential management practices
   • Store tokens in secure files with restricted permissions (chmod 600)
   • Use credential helpers when available

4. Token Permissions: Ensure your token has only the minimum required permissions for the tasks you need to perform.
