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:

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

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