## 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

## Email Domain Security Auditor — $0.50 per 1,000 domains

Audit public email-delivery and authentication DNS for a domain list. Each domain becomes one spreadsheet-ready row with MX provider, SPF, DMARC policy, tested DKIM selectors, MTA-STS, TLS-RPT, BIMI, a 0–100 readiness score, grade, and plain-English issues.

### Who uses it?

- MSPs and security agencies auditing client portfolios.
- Sales and marketing operations qualifying email-infrastructure leads.
- IT teams monitoring SPF/DMARC/DKIM drift on owned domains.
- Deliverability consultants prioritizing remediation work.
- Developers feeding domain posture into CRMs, agent tools, or dashboards.

### What makes it useful?

- One row per domain; no per-DNS-record billing surprise.
- Detects Google Workspace, Microsoft 365, Proofpoint, Mimecast, Zoho, and other common MX providers.
- Checks seven default DKIM selectors and accepts custom selectors.
- Flags multiple SPF records, weak SPF `all`, missing DMARC, and DMARC `p=none`.
- Uses the platform scheduler and webhooks for recurring portfolio checks.

### Input example

```json
{
  "domains": ["example.com", "client-one.com", "https://client-two.com/about"],
  "dkimSelectors": ["default", "google", "selector1", "selector2", "k1"],
  "includeRawDns": true,
  "maxConcurrency": 20
}
```

### Pricing

Domain audits cost **$0.0005 each ($0.50 per 1,000)** plus a $0.00005 Actor-start event. Platform usage is billed by Apify under the user's plan. A failed or nonexistent domain still creates one diagnostic row because list coverage itself is useful and auditable.

### Important limits

DNS cannot enumerate DKIM selectors, so the Actor tests the supplied selector list. A missing tested selector does not prove that no DKIM key exists. Scores are operational guidance, not a certification or vulnerability assessment. Query only public DNS and use results lawfully; do not use this Actor to facilitate spam or abuse.

# Actor input Schema

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

Website URLs are reduced to their hostname.

## `dkimSelectors` (type: `array`):

DKIM selectors cannot be enumerated. Add selectors used by your providers.

## `includeRawDns` (type: `boolean`):

Include A, AAAA, MX, NS, TXT, and CAA answers in each row.

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

Limit how many domains are audited at the same time.

## `timeoutSeconds` (type: `integer`):

Stop waiting for an individual DNS query after this many seconds.

## Actor input object example

```json
{
  "domains": [
    "google.com",
    "github.com",
    "apify.com"
  ],
  "dkimSelectors": [
    "default",
    "google",
    "selector1",
    "selector2",
    "k1",
    "s1",
    "s2"
  ],
  "includeRawDns": true,
  "maxConcurrency": 20,
  "timeoutSeconds": 8
}
```

# 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("scrapesignal_labs/email-domain-security-auditor").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("scrapesignal_labs/email-domain-security-auditor").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 scrapesignal_labs/email-domain-security-auditor --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,scrapesignal_labs/email-domain-security-auditor"
        }
    }
}

```

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).
