ZoomInfo & Lusha B2B Company & Contact Waterfall API

Enterprise B2B account firmographics, live website technology stack inspection, corporate E.164 phone numbers, and a multi-stage DNS MX-verified contact waterfall without requiring $15,000/yr ZoomInfo contracts or Lusha per-seat credits.

Built for Clay.com, n8n, Make.com, and AI Agents (MCP) with guaranteed structured JSON output and Pay-Per-Result ($0 on Empty) billing.

Why Use This Waterfall API Instead of Single-Source Scrapers?

Feature	Single-Source B2B Scrapers ($30–$50/mo)	coherent_edelweiss/zoominfo-lusha-waterfall-enricher
Data Coverage	Fails when a company isn't indexed in one directory	3-Stage Waterfall: On-page Contact Crawl → DNS MX Gateway Resolution → Role Routing
Pricing Model	Fixed monthly subscription or expensive credit packs	Pay-Per-Event ($0.002–$0.007/account) — $0 on empty results
Tech Stack & Pixel Signals	Outdated static tags	Live detection of CMS, Meta/Google/TikTok/LinkedIn pixels & CRM/Booking tools
Executive Account Brief	Raw unstructured fields	Structured account_intelligence_summary ready for SDR sequences
UK / EU GDPR Compliance	No regional filtering	Built-in gdprSafeMode (auto | strict | off) for UK/EEA corporate role-only filtering

Transparent Pay-Per-Event Pricing (Zero-Charge on Empty)

You only pay when verified account intelligence is returned:

• result-scraped ($0.002): Charged only when a valid company firmographic & tech-stack record is resolved.
• verified-contact-enriched ($0.003): Charged only when the DNS MX waterfall confirms active mail servers and verified corporate contact routes.
• ai-structured-summary ($0.002): Charged only when includeAccountIntelligence: true synthesizes an SDR account brief.

UK GDPR, EU GDPR & PECR Compliance Notice (Safe-by-Design)

• Stateless On-Demand Processor: This Actor is an ephemeral, on-demand software utility that executes within the user's isolated Apify container. The Actor developer does not store, aggregate, or resell any scraped datasets or personal data.
• Built-in gdprSafeMode (auto | strict | off): By default (auto), when a UK or EEA domain (.uk, .co.uk, .eu, .de, .fr, etc.) is detected, the Actor automatically filters out named personal emails (firstname.lastname@) and personal LinkedIn profile URLs (/in/), returning only non-personal corporate role endpoints (info@, sales@, contact@, enquiries@), corporate /company/ links, and website technology stack metadata.
• Controller Responsibility: Users disabling gdprSafeMode act as Data Controllers and are solely responsible for establishing a valid lawful basis (such as UK GDPR Article 6(1)(f) Legitimate Interests for corporate subscribers) and complying with UK PECR / EU ePrivacy rules.
