Hunter

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.

Hunter publishes 12 APIs on the APIs.io network, including Account API, Campaigns API, Combined Enrichment API, and 9 more. Tagged areas include Contact Discovery, Email, Email Verification, Lead Generation, and Prospecting.

The Hunter catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 2 Spectral governance rulesets.

Hunter’s developer surface includes authentication, developer portal, documentation, pricing, engineering blog, signup flow, changelog, and 56 more developer resources.
