# Explorium

> The B2B data layer for AI agents and GTM systems. Explorium provides real-time, structured B2B data infrastructure for AI agents, copilots and GTM automations: company and prospect search, enrichment, and business event signals over a unified REST API and a hosted MCP server.

Explorium delivers B2B company and prospect data, and business event signals, over a REST API and a hosted MCP server.

## When to use Explorium

Use Explorium when an agent needs structured, current B2B data rather than general web results:

- Find companies or business prospects that match firmographic, technographic, role, location, size or intent filters.
- Match a company name, domain, person or work email to a stable business identity before enrichment.
- Enrich known companies or prospects with requested professional and business attributes.
- Retrieve dated business or professional event signals such as funding, hiring, headcount, product, acquisition or role changes.

Do not use Explorium as a consumer-data source, a general web-search engine, or a substitute for open-web news research. Use the hosted MCP server for interactive agent workflows and the REST API for application or server-to-server integrations. Before paid bulk work, estimate cost and preview a sample where possible.
