Domain WHOIS and DNS Lookup: registrar, age, expiry (RDAP)

🌐 What is Domain RDAP and DNS?

Every domain or URL you list comes back as one row from RDAP, the official successor of WHOIS, with DNS lookups alongside. Unregistered ones are shown as available.

• Domain portfolios: see which of your domains expire in the next 90 days
• Lead qualification: check the age and mail setup of prospects' domains
• Security and fraud: flag newly registered domains in links, sign-ups or phishing reports
• Domain investing: check in bulk which names are still free

✨ Why use this Actor?

• ✅ Official source: RDAP from the registry, structured JSON instead of parsed WHOIS text
• ✅ Ready-made numbers: ageDays and daysToExpiry computed for you
• ✅ DNS in the same row: A, AAAA, MX, NS, SPF and the TXT count; switch off with dns: false
• ✅ Free or taken: unregistered domains get registered: false
• ✅ Pay per domain: 0.0024 USD per domain; failed inputs are not charged

🚀 How to use Domain RDAP and DNS

Domain RDAP and DNS works in a few clicks, no coding needed:

1. Create a free Apify account (the free plan includes 5 USD of monthly credit).
2. Open Domain RDAP and DNS and click Try for free.
3. Paste domains or URLs, one per line.
4. Click Start and wait for the run to finish (most runs take seconds).
5. Download your data as JSON, CSV, Excel, XML or HTML, or send it straight to Google Sheets, Make, Zapier or your AI agent.

⬇️ Input

Only domains is required; URLs are reduced to their domain.

DNS

On by default; dns: false skips the DNS lookups and returns the RDAP data only.

Country domains

RDAP covers all generic extensions (.com, .org, .app) and the country ones whose registry runs RDAP; others get result: unsupported and are not charged.

Field	Type	What it does	Default
Domains (domains)	array	Domains or URLs (the host is used, www.	["apify.com","github.com"]
DNS records (dns)	boolean	Add A, AAAA, MX, NS and SPF records.	true
Maximum retries (maxRetries)	integer	Retries per request with exponential backoff on network errors, 429 and 5xx.	3

Input example

{
    "domains": [
        "apify.com",
        "github.com",
        "bbc.co.uk"
    ]
}

⬆️ Output

Every domain becomes one row. The run summary (OUTPUT) counts answered, unsupported and failed domains.

🔌 Integrations, API and MCP

Connect Domain RDAP and DNS to your AI agent (MCP)

Give Claude, ChatGPT, Cursor or any MCP client direct access to Domain RDAP and DNS through the Apify MCP server. Add this URL to its settings:

https://mcp.apify.com/?actors=bepolabs/domain-rdap

For Claude Desktop, add it under mcpServers in claude_desktop_config.json:

{
    "mcpServers": {
        "domain-rdap": {
            "command": "npx",
            "args": [
                "-y",
                "@apify/actors-mcp-server",
                "--actors",
                "bepolabs/domain-rdap"
            ],
            "env": {
                "APIFY_TOKEN": "<your Apify API token>"
            }
        }
    }
}

Then ask: "Check these 30 domains and tell me which expire within 60 days and which have no MX record."

Run it from your code

Python (pip install apify-client):

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("bepolabs/domain-rdap").call(run_input={"domains":["apify.com","github.com","bbc.co.uk"]})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript (npm install apify-client):

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: '<YOUR_APIFY_TOKEN>' });
const run = await client.actor('bepolabs/domain-rdap').call({"domains":["apify.com","github.com","bbc.co.uk"]});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

No-code integrations

Send results to Google Sheets, Slack, Airtable, HubSpot, Make, Zapier, n8n and more from the Integrations tab, start runs on a schedule, or trigger your own endpoint with a webhook when a run finishes. The Apify API gives you full control over runs and datasets.

❓ FAQ

Why RDAP and not WHOIS?

RDAP is the official, structured successor of WHOIS that ICANN requires of every generic registry; it returns clean JSON instead of free text.

Does it show the owner's name?

Only what the registry publishes; since the GDPR most registries redact private owners, so the Actor does not promise owner contacts.

Can it check if a domain is free?

Yes; an unregistered domain gets registered: false.

Is it legal to use Domain RDAP and DNS?

The Actor queries open RDAP servers and the DNS, the services built for exactly these lookups. Keep within reasonable volumes and their terms.
