# Apollo Hello World

## Overview
Minimal working example demonstrating the three core Apollo.io API operations: people search, person enrichment, and organization enrichment. Uses the correct `x-api-key` header and `api.apollo.io/api/v1/` base URL.

## Prerequisites
- Completed `apollo-install-auth` setup
- Valid API key configured in `APOLLO_API_KEY` environment variable

## Instructions

### Step 1: Search for People (No Credits Consumed)
The People API Search endpoint finds contacts in Apollo's 275M+ database. This endpoint is **free** — it does not consume enrichment credits, but it also does not return emails or phone numbers.

```typescript
// hello-apollo.ts
import axios from 'axios';

const client = axios.create({
  baseURL: 'https://api.apollo.io/api/v1',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': process.env.APOLLO_API_KEY!,
  },
});

// People Search — POST /mixed_people/api_search
async function searchPeople() {
  const { data } = await client.post('/mixed_people/api_search', {
    q_organization_domains_list: ['apollo.io'],
    person_titles: ['engineer'],
    person_seniorities: ['senior', 'manager'],
    page: 1,
    per_page: 10,
  });

console.log(`Found ${data.pagination.total_entries} contacts`);
  data.people.forEach((person: any) => {
    console.log(`  ${person.name} — ${person.title} at ${person.organization?.name}`);
  });
  return data;
}

searchPeople().catch(console.error);
```

### Step 2: Enrich a Single Person (Consumes 1 Credit)
The People Enrichment endpoint returns full contact details including email and phone.

```typescript
// Enrich by email, LinkedIn URL, or name+domain combo
async function enrichPerson() {
  const { data } = await client.post('/people/match', {
    email: 'tim@apollo.io',
    // Alternative identifiers:
    // linkedin_url: 'https://www.linkedin.com/in/...',
    // first_name: 'Tim', last_name: 'Zheng', organization_domain: 'apollo.io',
    reveal_personal_emails: false,
    reveal_phone_number: false,
  });

if (!data.person) {
    console.log('No match found');
    return;
  }

### Step 3: Enrich an Organization (Consumes 1 Credit)
```typescript
// Organization Enrichment — GET /organizations/enrich
async function enrichOrg() {
  const { data } = await client.get('/organizations/enrich', {
    params: { domain: 'apollo.io' },
  });

const org = data.organization;
  if (!org) { console.log('No org found'); return; }

console.log(`Company:    ${org.name}`);
  console.log(`Industry:   ${org.industry}`);
  console.log(`Employees:  ${org.estimated_num_employees}`);
  console.log(`Revenue:    ${org.annual_revenue_printed}`);
  console.log(`HQ:         ${org.city}, ${org.state}, ${org.country}`);
  console.log(`Tech Stack: ${org.current_technologies?.slice(0, 5).map((t: any) => t.name).join(', ')}`);
}
```

### Step 4: Python Equivalent
```python
import os, requests

API_KEY = os.environ['APOLLO_API_KEY']
BASE = 'https://api.apollo.io/api/v1'
HEADERS = {'Content-Type': 'application/json', 'x-api-key': API_KEY}

# People search (free)
resp = requests.post(f'{BASE}/mixed_people/api_search', headers=HEADERS, json={
    'q_organization_domains_list': ['apollo.io'],
    'person_titles': ['engineer'],
    'page': 1, 'per_page': 5,
})
for p in resp.json().get('people', []):
    print(f"  {p['name']} — {p.get('title', 'N/A')}")

# Org enrichment (1 credit)
resp = requests.get(f'{BASE}/organizations/enrich',
    headers=HEADERS, params={'domain': 'apollo.io'})
org = resp.json().get('organization', {})
print(f"Company: {org.get('name')} ({org.get('estimated_num_employees')} employees)")
```

## Output
- People search results (name, title, company — no emails)
- Enriched person with email, phone, LinkedIn URL
- Enriched organization with industry, headcount, revenue, tech stack

## Error Handling
| Error | Cause | Solution |
|-------|-------|----------|
| 401 Unauthorized | Missing or invalid `x-api-key` header | Check `APOLLO_API_KEY` env var |
| 422 Unprocessable | Malformed request body | Verify JSON payload structure |
| 429 Rate Limited | Exceeded requests/minute | Wait and retry with exponential backoff |
| Empty `people` array | No matches for filters | Broaden titles/seniority or use different domain |
