Agent discovers pricing via standard x402 flow
Pay $0.05 per lookup in USDC on Base
Returns email, confidence score, title, company
250M+ contact database

1. Agent calls /find?first_name=...&last_name=...&domain=...
↓ API returns 402 + payment details

2. Agent pays $0.05 USDC
↓ x402 facilitator verifies payment

3. API returns enriched contact data
