## Pricing

from $1.50 / 1,000 audited company domains

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## 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`).

**The fastest B2B Domain Enrichment, Tech Stack Lookup, Ad Pixel Checker, and Email/DNS Security Auditor on Apify.**

Turn raw company domain lists from **Google Maps Scraper**, **Apollo**, **LinkedIn**, or **Clay** into high-converting B2B sales triggers in seconds. Instead of paying $295–$495/month for slow browser-based tools like **BuiltWith** or **Wappalyzer**, this Actor runs **ultra-fast protocol-level HTTP/2 & DNS audits** to instantly uncover:

- **Installed & Missing Ad Pixels** (Meta/Facebook Pixel, Google Ads, TikTok Pixel, LinkedIn Insight Tag, GA4, GTM, Bing Ads, Snapchat, Reddit, Criteo, Taboola)
- **CMS & E-Commerce Tech Stack** (Shopify, WooCommerce, Magento, BigCommerce, WordPress, Webflow, Wix, Squarespace, PrestaShop, Next.js)
- **Marketing Automation, CRM, Reviews & Chat** (Klaviyo, HubSpot, ActiveCampaign, Mailchimp, Omnisend, Brevo, Gorgias, Intercom, Zendesk, Hotjar, Yotpo, Judge.me, Trustpilot, Recharge)
- **Hidden Backend ESPs via DNS SPF** (Detect Klaviyo, SendGrid, Amazon SES, Mailgun, HubSpot, Salesforce, Marketo, and Postmark directly from DNS records)
- **DMARC & SPF Email Spoofing Security** (Google Workspace, Microsoft 365, Zoho, ProtonMail, Mimecast, Proofpoint, and DMARC `p=none` vs `quarantine`/`reject` policies)
- **Deep Business Emails, Phones & Social Profiles** (Automatically crawls `/contact` and `/about` fallback pages when the homepage has no email, plus LinkedIn, Instagram, Facebook, TikTok, YouTube, and X)
- **Multi-Language Cold Email Icebreakers** (Ready-to-send personalized opening lines in **English, Español, Português, Deutsch, and Français**)

### 🎯 High-Converting Use Cases for Agencies & Growth Teams

1. **Paid Media & Performance Agencies (Meta / TikTok / Google Ads):**
   Filter domains from Google Maps or E-commerce directories using `filterByMissingPixel: ["Meta Pixel", "TikTok Pixel"]`. Instantly pitch companies that are already paying for **Google Ads** or **GA4** but losing retargeting revenue because they don't have **Meta Pixel** or **TikTok Pixel** installed.
2. **Shopify & E-Commerce Retention Agencies (Klaviyo / CRO / SMS):**
   Identify active **Shopify** or **WooCommerce** stores with 50+ products (`estimated_pages_or_products`) that are missing **Klaviyo**, **Omnisend**, **Attentive**, or review apps (**Yotpo**, **Judge.me**, **Loox**).
3. **Cybersecurity, MSPs & Cold Email Deliverability Consultants:**
   Audit thousands of domains for `email_spoofing_risk: "HIGH_RISK"` or `dmarc_policy: "none"`. Pitch immediate DMARC/SPF hardening to companies on **Google Workspace** or **Microsoft 365**.
4. **Google Maps & Apollo Lead Enrichment in Clay / Make / n8n:**
   Pipe any list of websites from Apify's **Google Maps Scraper** directly into this Actor to append verified emails, phone numbers, social links, tech stack, and a ready-to-send `cold_email_icebreaker`.

***

### 🚀 How to Use (Step-by-Step Tutorial)

#### 1. In Apify Console

1. Paste your list of company domains (e.g., `gymshark.com`, `allbirds.com`, `klaviyo.com`) or full URLs into **Company Domains**.
2. Choose your audit options, lead filters, and **Cold Email Icebreaker Language** (`en`, `es`, `pt`, `de`, `fr`).
3. Click **Save & Start**.
4. Export the enriched dataset to **CSV, Excel, or JSON**.

#### 2. In Clay, Make, n8n, or Zapier

- **Clay Integration:** Add the Apify integration column, select **Website Tech Stack, Ad Pixel, Email & DNS Enricher**, pass your `{{domain}}` column, and map `missing_key_pixels`, `cms_platform`, `spf_senders`, `emails`, and `cold_email_icebreaker` directly into **Instantly** or **Smartlead**.
- **API / Webhook:** Chain automatically after a Google Maps or Apollo scrape via Apify Webhooks.

### 🛡️ Enterprise Security, Anti-SSRF & GDPR Compliance

- **Strict SSRF & Cloud Metadata Protection:** Validates every redirect hop and ensures all resolved IPv4/IPv6 addresses are strictly global/public. Blocks private networks (`10.0.0.0/8`, `192.168.0.0/16`, `172.16.0.0/12`), CGNAT (`100.64.0.0/10`), loopbacks (`127.0.0.1`), and cloud metadata endpoints (`169.254.169.254`).
- **DNS-Rebinding Defense:** Direct IP-pinning with TLS SNI verification prevents time-of-check to time-of-use (TOCTOU) DNS manipulation.
- **GDPR & CAN-SPAM Compliance:** Extracts only publicly listed business contact details. Set `"extractContacts": false` to disable contact harvesting completely.
