  title: Hunter Count Gated Domain Search
  summary: Use the free Email Count to confirm coverage before spending a credit on Domain Search.
  description: >-
    A cost-aware discovery flow. The Email Count endpoint is free and consumes no
    credits, so it is used first to confirm Hunter actually has emails indexed for
    the domain. The flow branches on the returned total: when emails exist it runs
    a paid Domain Search to pull the actual addresses and pattern, and when the
    count is zero it ends the workflow without spending a credit on a domain that
    would return nothing. The free Email Count call carries no api_key, while the
    Domain Search inlines the api_key query parameter.
