## 🔌 Integration Guide

### 1. **Add to HTML Head:**

```html
<head>
  <!-- Design System -->
  <link rel="stylesheet" href="/static/css/design-tokens.css">

  <!-- Components -->
  <link rel="stylesheet" href="/static/css/enterprise-components.css">
  <link rel="stylesheet" href="/static/css/navigation.css">

  <script src="/static/js/accessibility.js"></script>
</head>
```

### 2. **Initialize on Page Load:**

```javascript
document.addEventListener('DOMContentLoaded', async () => {
  // Initialize provider discovery
  await providerDiscovery.init();

  // Render providers
  providerDiscovery.renderProviders('providers-container', {
    category: 'market_data'
  });

  // Show welcome toast
  toast.success('Dashboard loaded successfully!');
});
```

### 3. **Use Components:**

<!-- Provider Card (auto-generated) -->
<div id="providers-grid" class="grid grid-cols-3 gap-4"></div>

<script>
  providerDiscovery.renderProviders('providers-grid', {
    sortBy: 'priority',
    limit: 12
  });
</script>

<!-- Manual Card -->
<div class="card">
  <div class="card-header">

## 🎯 Provider Auto-Discovery - Deep Dive

### Folder Scanning (Future Enhancement)

The engine is designed to scan these folders:
```
/providers/
/config/
/integrations/
/api_resources/
/services/
/endpoints/
```

### Currently Supported Config

The engine reads `providers_config_ultimate.json` with this structure:

```json
{
  "schema_version": "3.0.0",
  "total_providers": 200,
  "providers": {
    "coingecko": {
      "id": "coingecko",
      "name": "CoinGecko",
      "category": "market_data",
      "base_url": "https://api.coingecko.com/api/v3",
      "endpoints": { ... },
      "rate_limit": {
        "requests_per_minute": 50,
        "requests_per_day": 10000
      },
      "requires_auth": false,
      "priority": 10,
      "weight": 100,
      "docs_url": "...",
      "free": true
    }
  }
}
```

### Health Checking

```javascript
// Manual health check
const result = await providerDiscovery.checkProviderHealth('coingecko');
// { status: 'online', responseTime: 234 }

// Auto health monitoring (every 60s for high-priority providers)
providerDiscovery.startHealthMonitoring(60000);
```
