  title: Hunter Domain Search, Find, and Verify
  summary: Search a domain for emails, find a named person's address, then verify it.
  description: >-
    A core prospecting flow built entirely on Hunter email intelligence
    endpoints. It searches a domain for known email addresses and patterns,
    finds the most likely address for a specific person at that domain, and
    then verifies the deliverability of the found address. Each step spells out
    its request inline, including the api_key query parameter, so the flow can
    be read and executed without opening the underlying OpenAPI description.
