## Pricing

from $1.00 / 1,000 results

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## 🧭 Domain Lead Qualifier – Email Readiness & WHOIS Intelligence API (Bulk Enrichment)

_Upload domains → get age, registrar, DNS auth & email-sendability score. Built for SDRs, lead-gen agencies & list vendors._

**Domain Lead Qualifier** helps SDR teams and growth operators qualify domains _before outreach_ using email readiness and deliverability signals, WHOIS/RDAP registration data, TLS status, and hosting intelligence. Run it from the Apify Console or automate it via API to score domains at scale and avoid low-quality or risky leads.

### ⭐ Key Features

- 🎯 **Bulk domain enrichment for lead qualification** — one result per domain
- 📬 **Email readiness & deliverability checks** — MX, SPF, DMARC + disposable detection
- 🧾 **WHOIS / RDAP intelligence** — domain age, registrar, expiry (with fallback)
- 🔒 **TLS validation** — certificate status and days to expiration
- 🌐 **Hosting context** — resolved IP, ASN, hosting organization
- 🧮 **Email-readiness score (0–100)** — 🟢 high / 🟡 medium / 🔴 low, fully configurable

### 💡 Why use this Actor?

- **Avoid bad leads** — filter domains with no MX, disposable email, or weak auth
- **Protect deliverability** — catch SPF/DMARC gaps _before_ campaigns go out
- **Audit lead vendors** — objectively score purchased lists at scale
- **Save SDR time** — prioritize outreach to high-scoring domains only

### 📥 Input

Configure the Actor from the **Input tab**. Only `domains` is required — everything else is optional.

#### `domains` (required)

Domains to enrich and qualify.

- URLs are automatically normalized to domains

#### `concurrency` (optional)

Controls how many domains are processed in parallel.

- Default: **10**
- Higher values are faster but use more memory

#### `scoring` (optional)

Customizes how the **email_score (0–100)** is calculated.

- If omitted, the Actor uses a production-ready default scoring model
- Use this only if you want to change how domains are ranked

#### Minimal example (most users)

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

> ✅ Uses **default concurrency and default scoring**.
> This is enough for most SDR, lead-gen, and list QA workflows.

#### Full example (explicit defaults shown)

The example below shows **all default values**.
You do **not** need to include this unless you want to override something.

```json
{
    "domains": ["example.com", "google.com"],
    "concurrency": 10,
    "scoring": {
        "weights": {
            "mx": 30,
            "spf": 15,
            "dmarc": 10,
            "domainAge": 25,
            "tls": 15,
            "notDisposable": 5
        },
        "thresholds": {
            "high": 70,
            "medium": 40
        }
    }
}
```

> 💡 **Partial overrides are supported.**
> You can change only `thresholds.high` (for example) and keep all default weights.

### 📤 Output

Each input domain produces one result object in the default dataset.

```json
{
    "domain": "example.com",
    "has_mx": true,
    "has_spf": true,
    "has_dmarc": true,
    "tls_valid": true,
    "is_disposable": false,
    "email_score": 100,
    "email_score_label": "high",
    "email_score_emoji": "🟢",
    "resolved_ip": "104.18.27.120",
    "domain_registered_at": "1995-08-14",
    "expires_at": "2026-08-13",
    "registrar": "RESERVED-Internet Assigned Numbers Authority",
    "domain_age_days": 11101,
    "tls_expires_in_days": 71,
    "hosting_cms": "unknown",
    "asn": 13335,
    "hosting_org": "Cloudflare"
}
```

**Key fields to watch**

- `email_score`, `email_score_label`, `email_score_emoji` — primary qualification signals
- `has_mx`, `is_disposable` — fast exclusion filters
- `domain_age_days`, `expires_at`, `registrar` — trust and risk indicators
- `tls_valid`, `tls_expires_in_days` — maintenance and security signals

> Per-domain lookup failures don’t crash the run. Partial results may include `*_error` fields.

### 🧠 Tips & Best Practices

- **Interpret the score**
  - 🟢 *High*: safe for outreach
  - 🟡 *Medium*: review or enrich further
  - 🔴 *Low*: exclude from cold email

- **Fast exclusion rules**
  - `has_mx = false`
  - `is_disposable = true`
  - `email_score_label = "low"`

- **When to customize scoring**
  - Don’t customize for general B2B qualification or list QA
  - Customize if you target very new startups, need strict compliance, or want higher auth requirements

- **Performance tuning**
  - Start with `concurrency = 10`
  - Increase only if runs are slow and memory usage is low
  - Reduce concurrency first if you see timeouts

### 🔌 Integrations

This Actor fits naturally into automated lead-qualification workflows:

- **Actor-to-Actor**: Trigger this Actor from another Actor or Task, or pass its dataset to a downstream Actor for filtering, enrichment, or export.
- **Automation tools**: Run it from Zapier, Make, n8n, or similar platforms using the same JSON input as in Apify Console.
- **Data pipelines**: Connect the output dataset to integration-ready Actors to upload results to databases, spreadsheets, or internal systems.

See Apify’s integration docs for setup details.

### 🚀 Get Started

Upload a list of domains and get email-readiness scores fast.
Ideal for SDR teams, lead-gen agencies, and anyone qualifying leads before outreach.

# Actor input Schema

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

List of domains to enrich. Add one domain per line, or use bulk edit. URLs will be automatically stripped to domain only.

## `concurrency` (type: `integer`):

Maximum number of domains to process in parallel. Higher values are faster but use more memory. Recommended: 10 for 1GB, 15-20 for 2GB+ memory.

## `scoring` (type: `object`):

Customize how email scores are calculated. Weights determine point values for each signal (default sum = 100). Thresholds determine score cutoffs for high/medium/low labels.

## Actor input object example

```json
{
  "domains": [
    "example.com",
    "google.com",
    "github.com"
  ],
  "concurrency": 10,
  "scoring": {
    "weights": {
      "mx": 30,
