Hunter
Find and verify professional email addresses, enrich people and companies, and run email outreach.
Updated Sep 27, 2026
Overview
Hunter finds and verifies professional email addresses: it lists the people
and emails behind a company domain, finds one person's email, checks
deliverability, discovers companies that match a profile, enriches people and
companies, and runs outreach sequences from saved leads. The hosted MCP server
covers all of it; Claude, ChatGPT and Gemini sign in with OAuth, and other
clients send the API key in an X-API-Key header. The REST API accepts the
key in that header, as a Bearer token, or as the api_key query parameter.
Every plan, including the free one, can use the API and the MCP server. Usage counts against the plan's credits: a search uses 1 credit and a verification half a credit, while Discover (company search) is free.
