About Hunter

Hunter's API provides programmatic access to B2B email data for automated outreach workflows. It includes a Domain Search endpoint that returns email addresses associated with a given domain, an Email Finder endpoint that returns a professional email address given a person's name and domain, and an Email Verifier endpoint that checks the validity of an email address and returns a confidence score. A Discover endpoint allows querying for companies matching specified criteria, such as industry or headquarters location, using natural language or filters.

Returned data can include, depending on the endpoint, email confidence scores, source URLs where an address was found, a person's name, position, seniority, department, and social profiles, and verification status such as valid, disposable, or webmail. The API is intended for developers building lead generation, sales prospecting, or cold email outreach tools who need to find or validate email addresses at scale.
