LinkedInDataAPI vs People Data Labs · Coresignal · Proxycurl
$0.40 vs $25.00+
per 1,000 person enrichments.
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.
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).
