Data Enrichment APIs pricing
Data Enrichment APIs turn a thin identifier (email, domain, name, LinkedIn URL) into a full person or company profile: firmographics, contact details, job history, social and intent signals. The category splits into developer-first API houses with self-serve keys and transparent credit pricing (People Data Labs, Crustdata, Apollo, FullContact) and enterprise/sales-gated or platform-bundled players (ZoomInfo, Clearbit-now-Breeze inside HubSpot, Clay). Compare on documentation/DX, reliability and proven scale, ecosystem (SDK languages, MCP, webhooks), and accessibility, how fast a developer or AI agent can sign up, get a key, and ship without a sales call. Note: Proxycurl, a former category staple, permanently shut down on July 4, 2025 after a LinkedIn lawsuit and is excluded.
