## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## 🔍 Website Technology Profiler API (WhatRuns)

Instantly discover the entire **software, framework, and tool stack** powering any website on the internet. Perfect for competitor analysis, lead generation, market research, and developer security audits.

This edge-optimized tool queries an advanced website technologies database, processes complex chained tracking redirects, extracts frameworks, CMS platforms, analytics, and advertising packages, records programmatic PPE charge units, and maps clean visual answers.

***

### 🌟 Key Features

- **Deep Technology Profiles**: Instantly identify CMSs (WordPress, Shopify), frameworks (React, Next.js), analytics tools (Google Analytics, Mixpanel), widgets, fonts, and stylesheets.
- **Chained Redirect Cleaning**: Automatically decodes nested tracking URLs to present clean vendor homepages.
- **Blazing Fast Concurrent Execution**: Scans the target domain in milliseconds via concurrent edge routing.
- **Interactive Spreadsheet View**: Displays technology names, categories, target vendor urls, and profiled domains side-by-side.
- **Pay-Per-Event PPE Monetization**: Highly cost-effective pricing model charging only for successful technology profile lookups.

***

### 🛠️ How It Works

This Actor routes website profiling lookups to an edge-deployed gateway, processes domain inputs, queries real-time technology detection APIs, maps details to a key-value store, registers programmatic charge event metrics, and outputs structured sheets.

***

### 📥 Input Parameters

| Field | Type | Description | Prefill Example |
| :--- | :--- | :--- | :--- |
| **Target Website Domain** | `string` | The domain name of the website to profile. | `amazon.com` |

#### Input JSON Example

```json
{
  "domain": "amazon.com"
}
```

***

### 📤 Output Data Structure

Tabular datasets output clean rows mapping the account info:

#### Output JSON Example

```json
{
  "success": true,
  "domain": "amazon.com",
  "category": "Web Frameworks",
  "technology_name": "Next.js",
  "vendor_url": "https://nextjs.org",
  "icon_url": "https://www.whatruns.com/images/apps/Next.js.png"
}
```

***

### 💳 Monetization & Cost

This Actor utilizes the **Pay-Per-Event (PPE)** pricing model on the Apify Store:

- **Base Pricing**: Only **$4.00 per 1,000 successful lookups** (`$0.004` per event).
- **Pay as You Go**: If a lookup fails completely or returns no results, no billing charges occur.

# 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 = {
    "domain": "amazon.com"
};

// Run the Actor and wait for it to finish
const run = await client.actor("dev00/whatruns-api").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);
});

from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "domain": "amazon.com" }

# Run the Actor and wait for it to finish
run = client.actor("dev00/whatruns-api").call(run_input=run_input)

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