## 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

## Technology Profiling Engine

Identify technologies used by any website - React, WordPress, Shopify, Google Analytics & 7,000+ more. Deep 8-tier inspection with confidence scores. Like Wappalyzer but 10x cheaper: $5/1,000 URLs.

### Why Use This Actor?

- **7,000+ Technology Signatures** - The most comprehensive detection database

### Input

```json
{
  "urls": ["https://example.com", "https://another-site.com"],
  "timeout": 60,
  "proxyType": "datacenter"
}
```

#### Parameters

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| **urls** (required) | array/string | - | URLs to analyze |
| **timeout** | integer | 30 | Page timeout in seconds (10-120) |
| **proxyType** | string | datacenter | `datacenter` or `residential` (for protected sites) |
| **concurrency** | integer | 5 | Concurrent pages (1-50) |
| **minConfidence** | integer | 50 | Minimum confidence score (0-100) |
| **includeEvidence** | boolean | false | Include detection evidence in output |

#### URL Formats

All these formats work:

```json
// JSON array
["https://example.com", "https://example.org"]

// Line-separated
"https://example.com\nhttps://example.org"

// Comma-separated
"https://example.com, https://example.org"

// Single URL
"https://example.com"
```

### Output

```json
{
  "url": "https://www.example.com",
  "scan_timestamp": 1704067200,
  "status": "success",
  "technologies": [
    {
      "name": "React",
      "category": "JavaScript frameworks",
      "categories": ["JavaScript frameworks"],
      "groups": [{"id": 9, "name": "Web development"}],
      "confidence_score": 85,
      "confidence_tier": "Medium",
      "version": "18.2.0"
    },
    {
      "name": "Cloudflare",
      "category": "CDN",
      "categories": ["CDN"],
      "groups": [{"id": 7, "name": "Servers"}],
      "confidence_score": 60,
      "confidence_tier": "Medium"
    }
  ],
  "metadata": {
    "duration_ms": 8500
  }
}
```

#### Output Fields

| Field | Description |
|-------|-------------|
| `url` | Scanned URL |
| `status` | `success`, `failed`, or `timeout` |
| `technologies[].name` | Technology name |
| `technologies[].category` | Primary category |
| `technologies[].confidence_score` | Detection confidence (0-100) |
| `technologies[].confidence_tier` | `High` (90+), `Medium` (50-89), `Low` (<50) |
| `technologies[].version` | Version if detected |
| `metadata.duration_ms` | Scan duration |

### How It Works

#### 8-Tier Deep Inspection

Unlike simple HTML scrapers, this Actor inspects 8 different layers:

| Tier | What It Checks | Example Detections |
|------|----------------|-------------------|
| 1 | **HTTP Headers** | Cloudflare, nginx, security headers |
| 2 | **DOM/HTML** | Meta tags, script sources, CSS classes |
| 3 | **JavaScript** | Global variables (React, Vue, jQuery) |
| 4 | **Network** | XHR/Fetch to analytics, CDNs |
| 5 | **Storage** | localStorage keys (Redux, auth) |
| 6 | **PWA** | Service workers, manifest.json |
| 7 | **WebSocket** | Real-time connections (Socket.io) |
| 8 | **Cookies** | Cookie names (tracking, session) |

This catches technologies that surface-level scrapers miss.

### API Usage

#### Python

```python
from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")
run = client.actor("justa/technology-profiling-engine").call(
    run_input={"urls": ["https://example.com"]}
)

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(f"{item['url']}: {len(item['technologies'])} technologies found")
    for tech in item['technologies']:
        print(f"  - {tech['name']} ({tech['confidence_score']}%)")
```

#### JavaScript

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

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });
const run = await client.actor('justa/technology-profiling-engine').call({
    urls: ['https://example.com']
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach(item => {
    console.log(`${item.url}: ${item.technologies.length} technologies`);
});
```

#### cURL

```bash
curl -X POST "https://api.apify.com/v2/acts/justa~technology-profiling-engine/runs?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"urls": ["https://example.com"]}'
```

### Tips

#### For Protected Sites (Cloudflare, etc.)

Use residential proxy and increased timeout:

```json
{
  "urls": ["https://protected-site.com"],
  "proxyType": "residential",
  "timeout": 60
}
```

#### For Batch Processing

Scan hundreds of URLs efficiently:

```json
{
  "urls": ["url1", "url2", "...hundreds more..."],
  "concurrency": 10,
  "timeout": 30
}
```

### Pricing

- **$0.005 per URL** (~$5 per 1,000 URLs)
- Plus Apify platform costs (compute time)
- No subscriptions - pay only for what you use

# Actor input Schema

## `startUrls` (type: `array`):

URLs of websites to scan for technology detection. Add URLs individually, paste in bulk, or upload a text file.

## `concurrency` (type: `integer`):

Maximum number of pages to process concurrently

## `timeout` (type: `integer`):

Maximum time to wait for page load in seconds

## `minConfidence` (type: `integer`):

Minimum confidence score (0-100) to include a technology in results

## `batchId` (type: `string`):

## CLI example

```bash
echo '{
  "startUrls": [
    {
      "url": "https://example.com"
    }
  ]
}' |
apify call justa/technology-profiling-engine --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,justa/technology-profiling-engine"
        }
    }
}
```

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).
