## 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

## Domain Change Detection & DNS Audit Tool Actor

This Apify Actor allows IT security teams, domain managers, and infrastructure auditors to monitor specified domain URLs and their DNS records for any changes. It helps detect unauthorized updates or misconfigurations quickly by providing structured JSON snapshots of DNS records and content hashes of web pages.

### Features

- Fetches DNS records (A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV) using Google DNS-over-HTTPS API
- Retrieves HTTP(s) content of the domain home page and computes a SHA256 content hash
- Outputs structured JSON snapshots for each domain
- Designed for continuous monitoring and automation

### Input

Provide a JSON with:

- `domains`: an array of domain names or URLs

Example:

```json
{
  "domains": ["example.com", "https://example.net"]
}
```

Alternatively, a simple list of domain strings is accepted:

```json
[
  "example.com",
  "example.net"
]
```

### Output

Each dataset item has the format:

```json
{
  "domain": "example.com",
  "type": "snapshot",
  "dns": {
    "A": ["93.184.216.34"],
    "AAAA": [],
    "CNAME": [],
    "MX": [],
    "TXT": ["v=spf1 -all"],
    "NS": ["ns.example.com."],
    "SOA": [],
    "PTR": [],
    "SRV": []
  },
  "content_hash": "8a69f135ac69a1e5be4120577a5a67df3b066c0e7a974312ac9f208af04d4a51"
}
```

Errors are also reported with `type: "error"` and message field.

### Usage

Run the Actor with your input domains JSON or list.

Example run input:

```json
{
  "domains": ["example.com"]
}
```

The Actor fetches DNS and web content snapshot and stores JSON items in its default dataset.

#### Disclaimer

This Actor uses Google DNS-over-HTTPS public API for DNS record retrieval, respecting usage policies. It performs only allowed DNS record queries and HTTP GET requests to the domains provided.

# 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 = {};

// Run the Actor and wait for it to finish
const run = await client.actor("lavgroup/domain-change-detection-dns-audit-tool-3300068").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 = {}

# Run the Actor and wait for it to finish
run = client.actor("lavgroup/domain-change-detection-dns-audit-tool-3300068").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 '{}' |
apify call lavgroup/domain-change-detection-dns-audit-tool-3300068 --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,lavgroup/domain-change-detection-dns-audit-tool-3300068"
        }
    }
}
```

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).
