## 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

## B2B Domain Contact, Email Gateway, DNS SaaS & Tech-Stack Enricher (MCP-Ready)

Replace 3 separate outbound enrichment tools with a single **zero-browser, sub-second B2B Domain Intelligence API** built for **Clay.com**, **Instantly**, **Smartlead**, **n8n**, and **MCP AI Agents**.

For every company domain, this Actor extracts:

1. **Cold-Email Gateway & Deliverability (DNS MX / SPF / DMARC)**: Identifies `Google Workspace` vs `Microsoft 365` vs `Proofpoint` / `Mimecast` enterprise security gateways so cold-email agencies can segment sending inboxes and protect deliverability.
2. **Hidden Enterprise SaaS Stack via DNS TXT Fingerprints**: Uncovers internal B2B tools verified in root DNS `TXT` records even when invisible on the website (`OpenAI Enterprise / ChatGPT`, `Anthropic / Claude`, `Atlassian Cloud`, `Slack Enterprise`, `HubSpot`, `Stripe`, `Linear`, `Notion`, `Miro`, `DocuSign`, `OneTrust`, `Salesforce`, `Klaviyo`, etc.).
3. **Verified Website Contacts & Social Profiles**: Crawls the homepage and discovered `/contact`, `/about`, and `/impressum` subpages to extract clean business emails and company social links (`LinkedIn`, `X/Twitter`, `GitHub`, `YouTube`, `Instagram`, `Facebook`).
4. **Active Ad Pixels, Web Tech Stack & Funnel Signals**: Detects `Meta Pixel`, `Google Ads Tag`, `LinkedIn Insight Tag`, `TikTok Pixel`, `GTM`, `GA4`, `HubSpot`, `Intercom`, `Stripe`, `Shopify`, `Webflow`, `Next.js`, plus self-serve `/pricing`, `/docs`, and `/careers` ATS links.

### Integrations (Clay.com, Smartlead / Instantly, n8n, MCP AI Agents)

- **Clay.com & Smartlead / Instantly**: Route prospects using `Google Workspace` vs `Microsoft 365` vs `Mimecast` to separate sending pools, and personalize cold outreach using hidden DNS-verified Enterprise SaaS (`OpenAI Enterprise`, `Atlassian`, `HubSpot`).
- **Claude / Cursor / n8n MCP**: Add to your Apify MCP Server so AI agents can research any company domain in under 1 second.

### Complete Your B2B Outbound Buying-Signal Stack

Combine this Actor with our companion zero-browser B2B Intelligence APIs on Apify Store:

- **[Multi-ATS Career Jobs & B2B Tech-Stack Hiring Signal API](https://apify.com/ramirez911/multi-ats-hiring-signal-api)** — Pass the discovered `careersUrl` or company slug to extract open roles, salaries, hiring velocity scores, and 65+ tech-stack signals across Greenhouse, Ashby, Lever, SmartRecruiters, and Recruitee.
- **[Google Ads Transparency & B2B Ad-Spend Signal API](https://apify.com/ramirez911/google-ads-transparency-api)** — Check whether each domain is actively spending on Google Search & YouTube Ads, inspect evergreen creatives (`daysActive`), and pull EU DSA impression metrics.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "domains": [
        "linear.app",
        "shopify.com",
        "alza.cz"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("ramirez911/b2b-domain-tech-contact-enricher").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

# Run the Actor and wait for it to finish
run = client.actor("ramirez911/b2b-domain-tech-contact-enricher").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")

## CLI example

```bash
echo '{
  "domains": [
    "linear.app",
    "shopify.com",
    "alza.cz"
  ]
}' |
apify call ramirez911/b2b-domain-tech-contact-enricher --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,ramirez911/b2b-domain-tech-contact-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).
