# Bulk WHOIS lookup

**Use case:** 

Bulk WHOIS lookup for a list of domains: registrar, creation and expiry dates, domain age and registrant organisation where the registry publishes it. Uses RDAP first and falls back to registry WHOIS for TLDs without RDAP (.io, .co, .so, .de, .jp). One row per input, so results join back to your list.

## Input

```json
{
  "domains": [
    "stripe.com",
    "accenture.com",
    "notion.so"
  ],
  "checks": [
    "registration"
  ],
  "extraDkimSelectors": [],
  "concurrency": 10
}
```

## How it works

### 1. Sign up on Apify or log in

The Domain Intelligence & Enrichment — WHOIS, DNS, Email Provider Actor is ready to run with the inputs already set for "Bulk WHOIS lookup". [Sign up or log in](https://console.apify.com/create-task-from-example/QzLqWuFmZHxOcdoIU) and you'll land in Apify Console with a copy of this exact task.

### 2. Start the "Bulk WHOIS lookup" task

The Domain Intelligence & Enrichment — WHOIS, DNS, Email Provider Actor will start running based on the input automatically. You can also change all the input fields, like domains, urls or email addresses, checks to run, and more, to match your specific use case.

### 3. Receive the "Bulk WHOIS lookup" 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 input, domain, checked at (utc), and more.

### 4. Integrate into your workflow

The final output is delivered in JSON, CSV, or Excel format, ready to be plugged into your workflow. You can also [run the "Bulk WHOIS lookup" task via API](https://apify.com/brenton8907/domain-intel-check.md).

## About this Actor

This example demonstrates how to use [Domain Intelligence & Enrichment — WHOIS, DNS, Email Provider](https://apify.com/brenton8907/domain-intel-check.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/brenton8907/domain-intel-check.md) to learn more, explore other use cases, and run it yourself.


## 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/brenton8907/domain-intel-check.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`).
