ZeroBounce, Hunter.io & BuiltWith Alternative: Verify & Enrich 1,000 B2B Leads for $1.50 via Apify, n8n, Make, Clay & Claude MCP

Growth engineers, outbound agencies, and RevOps teams operating n8n, Make.com, Clay, Zapier, and Claude Desktop / Cursor MCP pipelines are moving away from $99–$299/month seat-locked subscriptions. With pay-per-event serverless Apify Actors, you only pay fractional cents per verified email, enriched B2B domain, or audited API endpoint.
