    headers = {
        "x-rapidapi-key": api_key,
        "x-rapidapi-host": "fresh-linkedin-profile-data.p.rapidapi.com"

## Usage in Dashboard

Once configured, the dashboard automatically enriches lead data:

### Before Enrichment:
```python
lead = {
    "contact_id": "c123",
    "linkedin_url": "https://linkedin.com/in/username"
}
```

### After Enrichment:
```python
lead = {
    "contact_id": "c123",
    "linkedin_url": "https://linkedin.com/in/username",
    "full_name": "John Doe",
    "headline": "CEO at Tech Company",
    "location": "San Francisco, CA",
    "current_company": "Tech Company",
    "current_title": "Chief Executive Officer",
    "experience": [...],
    "education": [...],
    "skills": ["Leadership", "Strategy", ...]
}
```

## Legal & Compliance

### What's Legal ✅
- Scraping **public** LinkedIn data (hiQ Labs v. LinkedIn precedent)
- Using for B2B lead enrichment
- Caching data for business purposes
- Providing value-added services to customers

### Best Practices ⚠️
- Use only for legitimate business purposes
- Don't resell raw LinkedIn data
- Respect privacy laws (GDPR, CCPA)
- Provide data opt-out mechanisms
- Be transparent with customers about data sources

### What to Avoid ❌
- Selling scraped data to third parties
- Storing sensitive personal data unnecessarily
- Excessive scraping (respect rate limits)
- Mixing with breached/unauthorized data

## Testing Your Integration

### Test Profile URLs:
```
https://linkedin.com/in/williamhgates
https://linkedin.com/in/jeffweiner08
https://linkedin.com/in/satyanadella
```

### Quick Test:
1. Add your `RAPIDAPI_KEY` to Spaces Secrets
2. Restart the Space
3. Go to "Consent/Event Audit" tab
4. Add a contact with a LinkedIn URL
5. Click "Refresh Data"
6. See enriched profile information!

---

## Troubleshooting

### "API Key Not Found" Error
**Solution:** 
- Verify `RAPIDAPI_KEY` is in Spaces Secrets
- Check spelling (case-sensitive)
- Restart Space after adding secret

### "Rate Limit Exceeded" Error
**Solution:**
- You've used your 50 free requests this month
- Wait until next month or upgrade plan
- Implement caching to reduce requests

### "Invalid Profile URL" Error
**Solution:**
- Use full LinkedIn URL: `https://linkedin.com/in/username`
- Remove trailing slashes
- Ensure profile is public

### Slow Response Times
**Solution:**
- First request may take 2-3 seconds (normal)
- Implement local caching for repeat requests
- Consider background job queue for bulk enrichment

---

## Alternative Options

### If You Need More Than 50/Month:

**Option 1: User OAuth**
- Have users connect their own LinkedIn
- Zero API costs
- Legal and compliant
- Already supported in this app!

**Option 2: Multiple RapidAPI Accounts**
- Rotate between 2-3 free accounts
- 150 requests/month total
- Good for early stage

**Option 3: Upgrade to Paid**
- $50/month gets you 20,000 requests
- Worth it once you have 3+ paying customers

---

## Advanced Features

### Caching Implementation
```python
def get_cached_or_fetch(linkedin_url: str) -> dict:
    cache_file = f"/data/linkedin_cache/{hash(linkedin_url)}.json"
    
    if os.path.exists(cache_file):
        with open(cache_file, 'r') as f:
            return json.load(f)
    
    profile = fetch_linkedin_profile(linkedin_url)
    
    if profile:
        os.makedirs(os.path.dirname(cache_file), exist_ok=True)
        with open(cache_file, 'w') as f:
            json.dump(profile, f)
    
    return profile
```

### Bulk Enrichment
```python
def enrich_lead_list(leads: list) -> list:
    enriched = []
    for lead in leads:
        if 'linkedin_url' in lead:
            profile = fetch_linkedin_profile(lead['linkedin_url'])
            if profile:
                lead.update(profile)
        enriched.append(lead)
    return enriched
```
