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.
