## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## 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.

# Actor input Schema

## `companyDomains` (type: `array`):

List of B2B company domains for full firmographic & decision-maker waterfall enrichment.

## `includeAccountIntelligence` (type: `boolean`):

Synthesizes an enterprise account executive brief covering tech stack, email security gateway, and decision-maker reachability.

## `gdprSafeMode` (type: `string`):

Controls personal data filtering: "auto" (default) automatically enforces corporate role-only emails (e.g. info@, sales@, enquiries@) and strips named personal data on .uk/.eu/EEA domains; "strict" enforces corporate role-only filtering globally; "off" returns all discovered corporate contacts (Controller must have lawful basis).

## Actor input object example

```json
{
  "companyDomains": [
    "apify.com",
    "stripe.com"
  ],
  "includeAccountIntelligence": true,
  "gdprSafeMode": "auto"
}
```

# Actor output Schema

## `dataset` (type: `string`):

Account-level firmographics, email security infrastructure, corporate phone numbers, and verified decision-maker contacts.

## `summary` (type: `string`):

JSON summary of records extracted and PAY_PER_EVENT billing telemetry

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,coherent_edelweiss/zoominfo-lusha-waterfall-enricher"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
