# Domain age, WHOIS and SSL expiry lookup

**Use case:** 

Look up many domains at once: registration date, domain age, registrar and expiry date from the official RDAP registries (the modern WHOIS), plus the SSL certificate issuer and how many days are left. Owner contact details are never collected. Handy for IT audits, due diligence and spotting certificates about to expire.

## Input

```json
{
  "domains": [
    "voi.com",
    "allbirds.com",
    "stripe.com",
    "vipps.no",
    "elkjop.no",
    "spotify.com",
    "wordpress.org"
  ],
  "includeDns": true,
  "includeDomainInfo": true,
  "maxResults": 0,
  "maxConcurrency": 10
}
```

## Output

```json

  "domain": {
    "label": "Website",
    "format": "text"
  },
  "cms": {
    "label": "CMS",

## 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/vindr/website-tech-stack-detector.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`).
