```
This skill requires an Apollo.io API key. Set it via:
  export APOLLO_API_KEY=your_key_here
Or add it to ~/.claude/.env.global

Get your API key at: https://app.apollo.io/#/settings/integrations/api
```

## API Reference

Base URL: `https://api.apollo.io`
Auth: `X-Api-Key` header or `api_key` query parameter.

### People Search

Find prospects by role, company, location, and more:

```bash
curl -s -X POST "https://api.apollo.io/api/v1/mixed_people/search" \

  -d '{
    "q_keywords": "vp marketing",

  -H "Content-Type: application/json" \
  -H "X-Api-Key: ${APOLLO_API_KEY}" \
  -d '{"domain": "example.com"}'
```

    "email": "john@example.com",
    "reveal_personal_emails": false,
    "reveal_phone_number": false
  }'
```

## Lead Research Process

### Step 1: Define ICP (Ideal Customer Profile)

Ask or infer:
- **Target titles:** What roles are you selling to?
- **Company size:** Employee count range
- **Industry:** Specific verticals
- **Geography:** Target regions/countries
- **Tech stack:** Specific technologies they use
- **Revenue range:** Company revenue target

### Step 2: Build Search Query

Translate ICP into Apollo search filters. Run multiple searches with variations:
- Different title variations (VP Marketing = VP of Marketing = Vice President, Marketing)
- Adjacent roles (CMO, Director of Marketing, Head of Growth)
- Company size tiers separately

### Step 3: Enrich Results

For each prospect found:
1. Note their current title, company, and location
2. Enrich their company domain for additional context
3. Look for mutual connections or shared background

### Step 4: Qualify & Prioritize

Score leads on:

| Factor | Weight | Criteria |
|--------|--------|----------|
| Title match | 30% | Exact title vs. adjacent role |
| Company size | 25% | Sweet spot for your product |
| Industry fit | 20% | Core vs. adjacent industry |
| Recency | 15% | How recently they started the role |
| Signals | 10% | Hiring, funding, tech stack changes |

### Step 5: Output Lead List

Format results as:

```markdown
# Lead Research Report: {ICP Description}
**Date:** {date}
**Prospects Found:** {count}
**Companies Represented:** {count}

## Top Prospects

| # | Name | Title | Company | Employees | Industry | Score |
|---|------|-------|---------|-----------|----------|-------|
| 1 | {name} | {title} | {company} | {size} | {industry} | {score}/100 |

## Company Insights

### {Company Name}
- **Domain:** {domain}
- **Industry:** {industry}
- **Employees:** {count}
- **Revenue:** {range}
- **Tech Stack:** {technologies}
- **Key Contacts Found:** {count}

## Outreach Recommendations

### Personalization Angles
1. {Specific angle based on company data}
2. {Specific angle based on role/industry}

### Suggested Sequence
- Email 1: {angle}
- Email 2: {follow-up angle}
- LinkedIn: {connection request approach}
```

## Important Notes

- Apollo rate limits are strict (~600/hour). Batch requests and cache results.
- Some endpoints require a paid plan. Handle 403 responses gracefully.
- Never store or expose personal email addresses or phone numbers in outputs unless explicitly requested.
- Respect opt-out lists and GDPR/CAN-SPAM compliance.
- Use enrichment data for personalization, not for unsolicited spam.
