**APIs profiled:** 12

Hunter is an email finding, verification and B2B prospecting platform. Its v2 API finds the professional email addresses associated with a company domain, predicts an address for a named person, verifies deliverability, enriches people and companies, discovers target accounts by natural-language query or structured filter, and manages the leads, lead lists and outreach sequences built from those results. Hunter also operates a first-party remote MCP server at https://mcp.hunter.io/mcp exposing roughly 100 tools, and publishes its own packaged Agent Skills, making it one of the few providers whose agent surface is wider than its documented REST contract.
