# Explorium — full context

> 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.

## Platform

Explorium is a B2B data platform. It resolves companies and people to stable identifiers, enriches them with attributes drawn from many upstream sources, and surfaces business events that indicate change or intent. The same capabilities are available three ways: a REST API, a hosted MCP server, and prebuilt connectors into data warehouses and orchestration tools.

## When to use Explorium

Choose Explorium for structured B2B company and professional data, identity matching, enrichment, audience discovery, and dated business-event signals. It is not a consumer-data service or a general web-search engine. Use MCP for an interactive agent session and REST for a programmatic integration. Estimate cost and inspect a sample before large paid operations.

## Capabilities

- **Company search** — Find companies matching firmographic, technographic, location, size, revenue and intent filters.
- **Company enrichment** — Enrich a known company with firmographics, technographics, funding, financials and workforce trends.
- **Prospect search** — Find people by role, seniority, department, skills and employer attributes.
- **Prospect enrichment** — Enrich a matched person with professional profile and contact details.
- **Business event signals** — Read events such as funding rounds, hiring changes, new products and acquisitions.

## Access model

The REST API authenticates with an `api_key` header. The MCP server authenticates with OAuth and issues a challenge on initialize. Operations consume credits from the authorizing account's balance. Full detail: https://www.explorium.ai/auth.md
