🔴find_email(first_name, last_name, company_domain, company_name, linkedin_url, ...)
Find and verify one person's work email from their name and company domain, or from a LinkedIn company page URL when you do not have the domain. Costs 1 credit only when the result is verified. Misses, catch-alls, and cached repeats are free and still return at 0 credits. A billable result fails at 0 balance; the error includes https://www.findleademails.com/pricing. This stores the lookup. It does not delete or modify the person's data.

}🟡verify_email(email)
Check whether one email address is a real mailbox. Costs 1 credit only when the mailbox is confirmed valid. Invalid, catch-all, unknown, and repeats are free and still return at 0 credits.
