## 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

## Bulk Email Validator & Catch-All Verifier API ($0.50 / 1,000 Emails)

Verify thousands of B2B and consumer email addresses per minute for **Smartlead**, **Instantly**, **Clay.com**, **n8n**, **Make**, and **MCP AI Agents** at **just $0.50 per 1,000 emails** — **2× to 10× cheaper than ZeroBounce, NeverBounce, and BounceVerify**, running **100% browserless in 256 MB RAM**.

***

### What It Checks Per Email Address

1. **RFC 5322 Syntax & Plus-Alias Normalization**: Strips invalid characters and normalizes `+` aliases into `normalizedEmail`.
2. **Live DNS MX Mail Server Verification**: Queries Cloudflare DNS-over-HTTPS (`DoH`) in sub-20ms with domain-level caching to confirm active mail exchangers (`hasMxRecords`, `mxRecords`).
3. **Email Gateway & Catch-All Security Fingerprinting (`emailProvider`, `isSecurityGateway`)**: Identifies `Google Workspace`, `Microsoft 365 (Exchange Online)`, `Proofpoint Enterprise Gateway`, `Mimecast Security Gateway`, `Barracuda`, `ProtonMail Business`, `Zoho Mail`, `Cloudflare Email Routing`, and custom SMTP servers.
4. **SPF & DMARC Domain Authenticity (`hasSpf`, `hasDmarc`, `dmarcPolicy`)**: Detects whether a corporate domain has active email authentication (`reject` / `quarantine` / `none`) vs parked or unconfigured domains.
5. **Disposable / Burner & Role Inbox Detection**: Flags 400+ disposable temp-mail providers (`mailinator.com`, `yopmail.com`, `10minutemail.com`, `guerrillamail.com`, etc.), generic shared role accounts (`info@`, `support@`, `sales@`, `admin@`), and consumer free-mail domains (`gmail.com`, `outlook.com`, `yahoo.com`).

# 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 = {
    "emails": [
        "press@shopify.com",
        "founders@linear.app",
        "support@alza.cz",
        "fake@mailinator.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("ramirez911/bulk-email-validator-verifier-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 = { "emails": [
        "press@shopify.com",
        "founders@linear.app",
        "support@alza.cz",
        "fake@mailinator.com",
    ] }

# Run the Actor and wait for it to finish
run = client.actor("ramirez911/bulk-email-validator-verifier-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 '{
  "emails": [
    "press@shopify.com",
    "founders@linear.app",
    "support@alza.cz",
    "fake@mailinator.com"
  ]
}' |
apify call ramirez911/bulk-email-validator-verifier-api --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,ramirez911/bulk-email-validator-verifier-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).
