enrichment-waterfall

Build multi-vendor data enrichment waterfalls in n8n — cascading API calls across SerpAPI, Hunter.io, Apollo, Clearbit, LLM extractors, and scrapers with cost-aware fallbacks. Use this skill whenever the user wants to enrich leads, contacts, companies, or any entity with external data in n8n — phrases like "lead enrichment", "email finder", "data waterfall", "Clay alternative", "find LinkedIn profile", "get company info", "enrich this list of leads". Also use when designing any flow where multiple vendors are tried in sequence until one succeeds. Use this skill before designing such workflows because naive sequential API calls produce $10/lead costs — the waterfall pattern drops that to $0.10 by ordering vendors correctly.
