Explorium

Explorium is a B2B data foundation for AI agents and go-to-market teams. Its AgentSource API is a single external-data and enrichment platform - one API plus a native MCP server - that resolves, fetches, enriches, and monitors a business dataset of 150M+ companies and a prospect dataset of 800M+ people aggregated from 100+ external sources. Capabilities include entity matching, filtered fetch and market-sizing stats, autocomplete, 30+ firmographic / technographic / financial / prospect-contact enrichment endpoints (single and bulk up to 50 records), real-time business and prospect event tracking with webhooks, and a shared credit pool that meters all usage. The API is hosted at https://api.explorium.ai, authenticated with an API_KEY header, and gated behind an Explorium account with a free 100-credit developer tier.
