# Bulk domain age checker: WHOIS creation date for a domain list

**Use case:** 

Looks up the WHOIS registration date and age in years of every domain you paste, alongside HTTP status, load time, SSL, DNS and a 0-100 technical score. This example checks 10 SEO-industry .com sites: at most 10 rows (~$0.05). Some newer TLDs (e.g. .app) publish no creation date, so age stays blank there and the row is still charged. Paste up to hundreds of domains or a CSV URL.

## Input

```json
{
  "domains": [
    "moz.com",
    "ahrefs.com",
    "semrush.com",
    "backlinko.com",
    "searchenginejournal.com",
    "searchengineland.com",
    "neilpatel.com",
    "hubspot.com",
    "yoast.com",
    "wordstream.com"
  ],
  "maxConcurrency": 10,
  "timeout": 15,
  "includeMetaTags": true,
  "includeDns": true,
  "includeSsl": true,

## 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/zhorex/domain-authority-checker.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`).
