2026 B2B Enrichment & People Data API Benchmarks
Compare B2B data providers head-to-head.
See how LinkedInDataAPI ($0.40–$1.00 per 1,000 profiles, ~14ms hot-cache p50, and drop-in /api/v2/linkedin + ?domain= support) stacks up against Proxycurl, Clearbit, Apollo, and People Data Labs.
Cost per 1,000 enriched B2B profiles / companies
Pro & Business packages add +40% to +65% bonus credits, bringing effective enrichment cost down to $0.40–$0.575 per 1,000 profiles (and $0.08 per 1,000 decision-maker search items).
LinkedInDataAPI vs Proxycurl
Proxycurl charges $0.02–$0.10 per profile ($20–$100 per 1,000 lookups) and expires credits on lower tiers. LinkedInDataAPI provides a drop-in /api/v2/linkedin compatibility route, 5-provider automatic failover, and cuts your enrichment bill by up to 96%.
LinkedInDataAPI vs Clearbit (HubSpot Breeze)
Following HubSpot's acquisition and rebranding of Clearbit into Breeze Intelligence, standalone developer API access requires enterprise bundling. LinkedInDataAPI gives developers instant self-serve `domain -> company` and `username -> profile` enrichment starting at $19/mo or $25 never-expiring PAYG.
LinkedInDataAPI vs Apollo.io API
Apollo.io's API enforces strict per-minute/hourly rate limits tied to human sales seats and restricts programmatic bulk enrichment. LinkedInDataAPI is purpose-built for automated pipelines with up to 600 RPM concurrency and $0.08–$0.20 per 1,000 decision-maker search results.
LinkedInDataAPI vs People Data Labs (PDL)
Static B2B database vendors rely on quarterly or monthly batch dumps that miss recent job changes and new startups. LinkedInDataAPI combines a 7-day hot PostgreSQL cache with live real-time upstream resolution at a fraction of PDL's price.
LinkedInDataAPI vs Coresignal
Coresignal specializes in multi-terabyte raw data dumps and complex multi-endpoint credits that require dedicated ETL pipelines. LinkedInDataAPI delivers clean, normalized JSON over a fast REST API with zero ETL maintenance.
LinkedInDataAPI vs Crunchbase API
Crunchbase's commercial API requires expensive annual enterprise licensing just to enrich company headcount and leadership rosters. LinkedInDataAPI combines company firmographics, funding summaries, decision-maker rosters, and live job openings in one affordable developer API.
