Access the world's most accurate technology intelligence data programmatically. The HG Insights API v2 returns firmographic, technographic, and IT spend data for any company in a single call — on demand, without manual exports.
A single API call returns firmographic, technographic, and IT spend data for any company. Dedicated endpoints surface Functional Area Intelligence and corporate hierarchy. You control which data you get, and you only pay for what you use.
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.
POST /companies/enrich returns data organized into three field groups you can request independently based on your subscription:
Firmographics — Company name, location, industry, revenue, employee count, and other core attributes.
Technographics — Technology installations including products, vendors, and usage signals.
Spend — IT spending estimates by technology category.
Two additional endpoints return data not available through /enrich:
Functional Area Intelligence (/companies/functional-areas) — Department-level technology usage and decision maker job titles by location. See the FAI guide.
Corporate Hierarchy (/companies/hierarchy) — Full company tree from global HQ down to subsidiaries.
The field groups and endpoints available to you depend on your plan. Contact your account manager if you need access to additional data.
