## 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

## Tech Enricher — Website Stack & Email/DNS Detector

Give it a list of domains. Get back the CMS, ecommerce, analytics, marketing, support, hosting/CDN, and frontend framework technologies each one runs — plus its email provider and DNS host, from public DNS records.

A pay-as-you-go alternative to Wappalyzer and BuiltWith. No subscription, no seat fees.

### What you get per domain

| Field | Example |
|---|---|
| `technologies` | React, Next.js, Cloudflare, Google Analytics |
| `technologiesByCategory` | `{"Frontend": ["React"], "Hosting": ["Cloudflare"]}` |
| `emailProvider` | Google Workspace, Microsoft 365, Zoho Mail, or a mail security gateway in front of the mailbox (Mimecast, Proofpoint, Cisco Secure Email, Broadcom/Symantec MessageLabs, Barracuda), from MX records, lowest preference number first (the server mail is actually delivered to; higher-numbered records are backups). `null` when no MX host is a recognised provider (e.g. self-hosted mail) |
| `dnsProvider` | Cloudflare DNS, AWS Route 53, GoDaddy DNS, MarkMonitor, Akamai Edge DNS, Wix DNS, … (from NS records). `null` when the nameservers aren't a recognised provider |
| `spfSenders` | third-party services allowed to send mail as this domain, from SPF |
| `server`, `finalUrl`, `httpStatus` | raw signal for debugging |

### How it works

100% public data, no logins:

- Fetches the domain's homepage (https, falling back to http) and matches its HTML, script tags, response headers, and Content-Security-Policy (which reveals tags loaded dynamically via a tag manager, not just static `<script>` tags) against fingerprints for 84 technologies: Analytics 15, CMS 11, Frontend 10, Hosting/CDN 9, Marketing 9, Support 7, CRM 5 (Salesforce, HubSpot CRM, Pipedrive, Zoho SalesIQ, Freshsales), Ecommerce 4, Recruiting/ATS 4, Payments 3, Video 3, Fonts 2, A/B testing 2. CRM fingerprints only count a script the page actually loads (a `<script src>` or the CSP), not a link or a mention in the text, so a link to a Salesforce login page or a domain like workforce.com doesn't read as "uses Salesforce".
- Looks up MX, NS, and TXT (SPF) records over DNS-over-HTTPS to identify the email provider, DNS host, and third-party mail senders.
- Respects `robots.txt`: skips domains that disallow root-path fetches.

### Use cases

- **Sales & RevOps:** find accounts running the stack you integrate with or replace (e.g. "on WooCommerce, not Shopify").
- **Recruiting agencies / hiring-signals pairing:** cross-reference detected ATS (Greenhouse/Lever/Ashby/Workable) with [Hiring Signals](https://apify.com/toolfoundry/hiring-signals) for a full pipeline.
- **Competitive & market research:** track which analytics/marketing tools a market segment standardizes on.
- **Security/IT vendor risk:** inventory external services a domain depends on (CDN, email, chat, forms) without agent installs.

### Input

Domains, URLs, or email addresses. Each is reduced to its hostname: scheme, `www.`, `user@`, port, path, `?query` and `#fragment` are dropped, so `https://www.stripe.com/pricing?ref=abc` and `jane@stripe.com` both become `stripe.com`.

### Pricing

**$0.02 per profiled domain** ($20 per 1,000), versus $250–450/month for Wappalyzer or BuiltWith plans. Unreachable, robots-blocked, bot-protected (HTTP 4xx/5xx), unparseable, bare-IP, and `localhost` / private-network inputs are free (returned as `found: false`). IP addresses and private names are rejected before anything is fetched. Set a max charge per run and the Actor stops cleanly when it's reached.

Duplicates are charged once. Inputs are deduplicated on the domain they reduce to, before anything is fetched: `stripe.com`, `STRIPE.COM`, `www.stripe.com` and `stripe.com?ref=abc` in one run give one charged profile. Each later duplicate still gets its own row, free, with `duplicateOf` set to the input that was profiled.

### Limits & honesty

- Homepage-only detection: technologies used exclusively on subpages (e.g. checkout, docs) won't show up.
- Signatures favor precision over recall — some technologies won't be flagged if they don't leave a homepage-visible marker. Report `found: false` and inaccuracies as an issue; fingerprints get added on request.
- No firmographic data (employee count, revenue, etc.) is included — none of that is available from public, unauthenticated sources without violating a platform's terms.

# Actor input Schema

## `domains` (type: `array`):

Domains or URLs to profile, e.g. 'stripe.com' or 'https://ramp.com'.

## `maxConcurrency` (type: `integer`):

How many domains to process in parallel.

## Actor input object example

```json
{
  "domains": [
    "stripe.com",
    "ramp.com",
    "webflow.com"
  ],
  "maxConcurrency": 5
}
```

# 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": [
        "stripe.com",
        "ramp.com",
        "webflow.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("toolfoundry/tech-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("toolfoundry/tech-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": [
    "stripe.com",
    "ramp.com",
    "webflow.com"
  ]
}' |
apify call toolfoundry/tech-enricher --silent --output-dataset

```

## MCP server setup

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