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.
A single call to /companies/enrich returns firmographics, technographics, IT spend, AI maturity, and contracts. Dedicated endpoints surface Functional Area Intelligence, corporate hierarchy, and intent signals (HG Contextual Intent + TrustRadius buyer activities). 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 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.
AI Maturity — Composite AI readiness score (0–100), global rank, 6-month score delta, data maturity level (LOW/MEDIUM/HIGH), cloud intensity by provider (AWS/Azure/GCP), and GenAI buying intent score.
Contracts — Technology contract records including vendor, deal value, start/end dates, and active status.
Dedicated 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.
Intent Signals (/intent/enrich) — HG Contextual Intent (topic-based signals showing what a company is actively researching) and TrustRadius buyer activities (first-party signals from product page views and comparisons). See the Intent guide.
Contract Search (/contracts/search) — Search and filter contracts across companies by vendor, category, deal value, dates, and active status.
Contacts (/contacts/search, /contacts/enrich) — Find decision makers and influencers by job function, seniority, location, and time in role. Enrich contacts by ID to retrieve email and phone.
The field groups and endpoints available to you depend on your plan. Contact your account manager if you need access to additional data.
