ZoomInfo is a B2B go-to-market intelligence platform whose contact and company database, buyer-intent signals, scoops and news feeds are sold to sales, marketing, operations and recruiting teams. Its API estate is mid-migration: the legacy Enterprise API on api.zoominfo.com is documented as deprecating, while the current GTM API on api.zoominfo.com/gtm ships six published OpenAPI specifications covering data, Copilot, GTM Studio, marketing, agents and platform. ZoomInfo also operates a hosted, OAuth-gated Model Context Protocol server at mcp.zoominfo.com and publishes 35 agent skills and a first-party CLI that talks to that MCP server rather than to REST.
