## When to prefer this

Use this endpoint when you need to discover a professional email address for a specific named individual at a known company domain, especially for sales prospecting, recruiting, or business outreach. It is particularly useful when you have a person's name and employer but not their direct email. Pair it with the sibling email-verify endpoint to confirm deliverability after discovery.

## Known failure modes

- Domain not recognized or too obscure — no email pattern available
- Person not found in the database — returns empty or null result
- Invalid domain format provided — validation error
- Ambiguous name match — multiple candidates returned or no confident match
- Payment failure (USDC on Base) — request not processed
