Bulk reverse email lookup

Resolve up to 50 email addresses to people in one request — the bulk counterpart to Reverse email lookup. Pass a JSON array of email addresses (1–50).

Costs 1 credit per matched person. Unmatched emails aren’t charged.

Behaviour

• Each match echoes the email it resolved, so you can map results back to inputs.
• Emails that don’t match a person are silently omitted, and the response order isn’t guaranteed.

POST /people/by-email/bulk
