# Bulk DNS and WHOIS lookup for a list of domains

**Use case:** 

For each domain: name servers, mail hosts and mail provider, SPF and DMARC policy, plus registration data from RDAP, the successor to WHOIS, where the registry publishes it: registrar, creation and expiry dates and domain age. Only public DNS and RDAP records are read. One row per domain, exportable as JSON, CSV or Excel.

## Input

```json
{
  "domains": [
    "github.com",
    "linear.app",
    "vercel.com",
    "stripe.com"
  ],
  "modules": [
    "dnsRdap"
  ],
  "maxPagesPerDomain": 4,
  "contactPolicy": "business-only",
  "concurrency": 15,
  "timeoutSecs": 20
}
```

## Output

```json
{
  "domain": {
    "label": "Domain",
    "format": "string"
  },
  "dns": {
    "label": "DNS",
    "format": "object"
  },
  "rdap": {
    "label": "Registration",
    "format": "object"
  }
}
```

The Domain Tech Stack, Contacts & SEO Profiler Actor will start running based on the input automatically. You can also change all the input fields, like domains, checks to run, and more, to match your specific use case.

### 3. Receive the "Bulk DNS and WHOIS lookup for a list of domains" output

Monitor the progress in real time. You will be notified as soon as your dataset is complete and ready for review. Each result includes data such as domain, DNS, and registration.

### 4. Integrate into your workflow

## About this Actor

This example demonstrates how to use [Domain Tech Stack, Contacts & SEO Profiler](https://apify.com/tinlark/domain-intelligence-profiler.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

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 full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/tinlark/domain-intelligence-profiler.md

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`).
