B2B company and contact data for AI agents and apps, sold as prepaid credit packs. Lite is $29.99 for 500 credits, with a free 100-credit trial.

  • Desks that want prepaid credits instead of a seat tax
  • Developers on the AgentSource REST API
  • Recruiting teams enriching companies and prospects

ZoomInfo

Sales-quoted

Enterprise B2B contact graph with direct dials, org charts, technographics and intent. Quote-based, and overkill if you only need emails.

Where ZoomInfo fits

  • Account-based recruiting with intent data
  • Enterprise processes that already include the graph

Where they pull apart

Explorium

Stands out: Prepaid credit packs with a published per-credit rate, plus MCP for agents and a versioned REST API.

Watch out: Credits expire after 12 months and packs do not auto-renew. Enrichments cost 1 to 5 credits each, so 500 credits go fast.

Not the right fit for

  • Buyers who need a cheap monthly seat with unlimited pulls
  • Teams that refuse credit meters or 12-month expiry

ZoomInfo

Stands out: The buying-committee graph and intent data, not just email lookup.

Watch out: Recruiter-only desks should price Wiza, ContactOut or Tomba first. This is an enterprise contract.

Not the right fit for

  • Recruiter-only buyers signing a new enterprise contract
  • Teams that only need email and mobile lookup

Pros and cons

Explorium

  • Lite pack at $29.99 for 500 credits
  • Free 100-credit trial pack
  • MCP server plus REST API
  • Credits expire after 12 months
  • Enrichments can cost up to 5 credits
  • No seat plan with unlimited lookups

ZoomInfo

  • Org charts and intent, not only emails
  • MCP available
  • Strong value when sales already funds the seat
  • No public price
  • Enterprise contract and sales cycle
  • Overkill as a recruiter-only finder
