# 1. Go to https://openrouter.ai/
# 2. Sign up with email or GitHub

# 4. Click "Create Key"
# 5. Copy your key (starts with sk-or-...)

# OpenRouter charges ~10-20% markup over base model pricing

# In .env:
OPENROUTER_API_KEY=sk-or-v1-...
OPENROUTER_APP_NAME=openclaw-app  # Optional: appears in OpenRouter dashboard

# In config/providers.yaml:
providers:
  openrouter:
    api_key: ${OPENROUTER_API_KEY}
    base_url: https://openrouter.ai/api/v1
    default_model: anthropic/claude-3.5-sonnet

# In config/routing.yaml:
routing:
  default: anthropic/claude-3.5-sonnet

  rules:
    # Haiku for simple, structured tasks
    - patterns:
        - "summarize"
        - "format as (json|yaml|markdown)"
        - "translate to"
        - "list all"
      model: anthropic/claude-3-haiku

    # Opus for complex reasoning
    - patterns:
        - "analyze.*security"
        - "code review"
        - "debug.*issue"
        - "design.*architecture"
      model: anthropic/claude-3-opus

    # Sonnet for everything else (default)

# In config/routing.yaml (continued):
fallbacks:
  anthropic/claude-3-opus:
    - anthropic/claude-3.5-sonnet
    - openai/gpt-4
  anthropic/claude-3.5-sonnet:
    - anthropic/claude-3-haiku
    - openai/gpt-4o-mini
  anthropic/claude-3-haiku:
    - openai/gpt-4o-mini

retry:
  max_attempts: 3
  backoff_seconds: 2

# Test Haiku routing (should use haiku):
curl -X POST http://localhost:3000/api/chat \
  -H "Content-Type: application/json" \
  -d '{"message": "Summarize this conversation"}'

# Test Opus routing (should use opus):
curl -X POST http://localhost:3000/api/chat \
  -H "Content-Type: application/json" \
  -d '{"message": "Analyze the security implications of this code"}'

# Check logs to verify which model was used:
tail -f ~/.openclaw/logs/routing.log

# View routing statistics:
curl http://localhost:3000/api/routing/stats

# Expected output:
# {
#   "total_requests": 1240,

#     "anthropic/claude-3.5-sonnet": 510,
#     "anthropic/claude-3-opus": 110
