## 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

## 🏦 Google "About This Site" Metadata & Domain Intelligence API

Extract official Google Knowledge Graph site descriptions, salient image URLs, and Knowledge Graph entity MIDs directly from internal Chrome API gateways.

Bypass standard scraped SERPs entirely! This Actor leverages direct, binary Protobuf connections to retrieve official domain metadata, Wikipedia summaries, and registered knowledge entities. Ideal for domain intelligence, bulk SEO analysis, brand trust validation, and semantic topic indexing.

***

### 🌟 Key Features

- **Official Domain Descriptions**: Fetch Google's official registered text description and legal sources for any target website.
- **Knowledge Graph Entity MIDs**: Extract machine entity IDs (`/m/...` and `/g/...`) representing the semantic categories of the target site.
- **Salient Image Extraction**: Get high-quality site branding or logo image URLs extracted by Google's semantic indexing engines.
- **Wikipedia Source Mapping**: Resolves exact references used by the Google Knowledge Graph to build site confidence lists.
- **Ultra-Fast Performance**: Bypasses the latency and cost of running heavy browser-automation scrapers.
- **Organized Tabular Datasets**: Results are neatly formatted for seamless export to Excel, CSV, or HTML tables in the Apify Console.

***

### 🛠️ How It Works

This Actor queries an edge-optimized Cloudflare Worker gateway which crafts real-time binary Protobuf envelopes. It submits these payloads directly to Google's internal Chrome Optimization Guide endpoints, decodes the incoming stream, and parses structured entities on the fly.

***

### 📥 Input Parameters

| Field | Type | Description | Prefill Example |
| :--- | :--- | :--- | :--- |
| **Target Domain / URL** | `string` | The domain name or base URL to fetch intelligence for. | `google.com` |

#### Input JSON Example

```json
{
  "url": "google.com"
}
```

***

### 📤 Output Data Structure

Parsed results are output to the default dataset as a structured tabular row:

#### Output JSON Example

```json
{
  "success": true,
  "target_url": "https://google.com/",
  "description": "Google Search, or simply Google, is a search engine operated by Google.",
  "source_name": "Wikipedia",
  "source_url": "https://en.wikipedia.org/wiki/Google_Search",
  "salient_image_url": "https://encrypted-tbn0.gstatic.com/images?q=tbn:...",
  "entity_mids": [
    "/m/045c7b",
    "/g/11b816..."
  ]
}
```

***

### 💳 Monetization & Cost

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

- **Base Pricing**: Only **$1.00 per 1,000 domains** (`$0.001` per event).
- **No Server Execution Costs**: You are only charged for successful metadata extractions. If the domain has no recorded metadata or query fails, you pay nothing!

# 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 = {
    "url": "google.com"
};

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

## Python example

```python
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 = { "url": "google.com" }

# Run the Actor and wait for it to finish
run = client.actor("dev00/about-this-site-metadata-api").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}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "url": "google.com"
}' |
apify call dev00/about-this-site-metadata-api --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,dev00/about-this-site-metadata-api"
        }
    }
}

```

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).
