HG Insights API v2

Access the world's most accurate technology intelligence data programmatically. The HG Insights API v2 returns firmographic, technographic, IT spend, intent signals, and more for any company — on demand, without manual exports.

What You Can Build

AI agents and copilots — Give your AI agents real-time access to company intelligence. Whether you're building a sales copilot, a research agent, or a lead scoring system, the HG API provides the structured company data your agent needs to reason and act.

MCP integration — The HG API is compatible with the Model Context Protocol (MCP), making it easy to expose company data as a tool that any MCP-compatible agent or LLM can call directly. This enables workflows like automated account research, competitive analysis, and dynamic list building without manual data exports.

On-demand enrichment — Look up company data at the point of need: when a lead comes in, when a rep is prepping for a call, or when your app needs fresh context on an account.
