Yes. Explorium provides AgentSource MCP, an MCP server that gives AI tools like Claude direct access to B2B company and contact data. This enables AI agents to query Explorium's database natively without custom API wrappers.
Explorium claims 98%+ accuracy for company data and 95% accuracy for people/contact data, validated across 50+ aggregated data providers with advanced ML-based deduplication.
The default rate limit is 200 requests per minute per API key. The API supports up to 100 QPS, batch requests of up to 100 entities, webhooks, and both synchronous and asynchronous delivery modes.

Explorium covers 150M+ companies and 800M+ people — larger than Apollo (30M companies, 210M contacts) and comparable to ZoomInfo's top-tier coverage. Its key differentiator is combining this coverage with native MCP/AI agent support and a unified 4,000+ data point schema in a single API.
Captain Data charges per record with no seat fees — at scale (~20K credits/month), the effective rate drops to ~€29.99/1K credits. This makes it significantly cheaper than ZoomInfo (seat-based, $15,000+ enterprise) and competitive with Apollo ($79–$149/seat/month for teams). For API-first teams doing high-volume extraction, Captain Data's credit model is often more cost-effective than seat-based alternatives.
