Email discovery, verification, enrichment and company search: find the addresses behind a domain, look up a person or company, and build account lists with filters.
/domain-searchReturns the email addresses Hunter has found for a company domain, with names, positions, confidence scores and the domain's email pattern. Use when you know the company's website and want people to contact there. Unknown domains return an empty result and are still charged, so check the domain first.
/email-finderFinds the most likely email address for a named person at a company, verified, with a 0–100 confidence score and the sources it was seen on. Give the domain plus first and last name (or a LinkedIn handle). Charged only when an address is found.
/email-verifierChecks whether one email address is deliverable: SMTP and MX checks, catch-all and disposable detection, and a 0–100 confidence score. Use before sending to an address you found elsewhere.
/email-countHow many email addresses Hunter has for a domain, split into personal vs generic and by department and seniority. Free; use it to decide whether a domain search is worth paying for.
/multi-domain-searchOne query across every company matching your filters: returns one row per matching person with title, department, seniority, decision-maker flag and verification status, but the email itself masked behind a reveal_handle. Free. Pass the handles you want to /multi-domain-search/reveal to unlock the addresses. At least one filter is required.
/multi-domain-search/revealUnlocks the email addresses (and phone/LinkedIn when known) behind reveal_handle values from /multi-domain-search. Up to 100 handles per call. You pay per credit Hunter actually charges: one per personal email, one per domain for generic addresses, nothing for rows already revealed this period.
/people/findEverything Hunter knows about a person from their email address or LinkedIn handle: name, location, current employer and title, seniority, and social handles. Returns a provider 404 (no charge) when the person is unknown.
/companies/findCompany profile from a domain: legal name, description, industry codes, headcount, location, founding year, phone, social handles, tech stack and funding rounds. Returns a provider 404 (no charge) for unknown domains.
/combined/findOne call that returns both the person behind an email address and their company's profile. Cheaper than two enrichment calls when you have a work email.
/domain-finderResolves a company name to its most likely website domain(s), with logo and how many emails Hunter has for each. Free. Use before a domain search when you only have the company name.
/discoverBuild an account list from Hunter's company database: filter by HQ location, industry, headcount, company type, founding year, keywords, technology, funding or look-alikes, or just describe the companies in plain language with query. Each result carries how many emails Hunter has for it. Free; 100 companies per page.
/discover/peopleSame filters as /discover, but adds the total personal and generic email counts across every matching company (meta.total_emails). Free. Use it to size a campaign before paying for domain searches.
