Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## WHOIS Domain Lookup — Registrar, Age, Expiry & Nameservers (Bulk) **Look up WHOIS registration data for any domain** — registrar, creation and expiry dates, domain age, days until expiry, nameservers, and status codes — in **bulk, with no API keys**. Enter up to 10 domains, get back clean structured JSON. Built for **domain due diligence, expiry monitoring, brand protection, security research, and IT asset management**. Run it on the Apify platform with API access, scheduling, integrations, and monitoring built in. > This Actor queries **public WHOIS registry data** only, via the open-source > `whoiser` library (MIT). Registrant contact details are often redacted by registrars > under GDPR/ICANN policy — this Actor returns only what the registry publicly exposes. ### Why use WHOIS Domain Lookup? - **Bulk** — up to 10 domains per run - **No API keys, no setup** — public registry data - **Clean structured output** — dates normalized to ISO, age and expiry pre-calculated - **Nameservers & status codes** — full registry detail - **Pay per result** — $0.02 per domain looked up. No subscription. ### How to use WHOIS Domain Lookup 1. Enter one or more **domains** (bare domains like `example.com`). 2. (Optional) Adjust **follow depth** for richer referral data. 3. Click **Start** and read the results in the **Output** tab. ### Input | Field | Type | Description | |---|---|---| | `domains` | array | Up to 10 bare domains (protocol and `www.` stripped automatically) | | `domain` | string | Single-domain alternative | | `follow` | integer | WHOIS referral servers to follow, 1–3 (default 2) | ```json { "domains": ["example.com", "github.com"], "follow": 2 } ```` ### Output One dataset item per domain. ```json { "domain": "github.com", "status": "Looked up", "registrar": "MarkMonitor Inc.", "registrarUrl": "http://www.markmonitor.com", "createdDate": "2007-10-09T18:20:50.000Z", "updatedDate": "2024-09-07T09:16:33.000Z", "expiryDate": "2026-10-09T18:20:50.000Z", "domainAgeDays": 6820, "daysUntilExpiry": 485, "nameServers": ["dns1.p08.nsone.net", "dns2.p08.nsone.net"], "domainStatus": ["clientTransferProhibited"], "dnssec": "unsigned", "registryDomainId": "1264983250_DOMAIN_COM-VRSN", "lookedUpAt": "2026-06-11T10:32:00.000Z" } ``` You can download the dataset in various formats such as JSON, HTML, CSV, or Excel. ### Data table | Field | Description | |---|---| | `domain` | The domain looked up | | `registrar` | Sponsoring registrar | | `createdDate` / `updatedDate` / `expiryDate` | Registration dates (ISO 8601) | | `domainAgeDays` | Days since registration | | `daysUntilExpiry` | Days until the domain expires | | `nameServers` | Authoritative nameservers | | `domainStatus` | EPP status codes (e.g. clientTransferProhibited) | | `dnssec` | DNSSEC signing status | ### Pricing This Actor uses **pay-per-event** pricing: **$0.02 per domain successfully looked up**. Invalid domains and failed lookups are not charged. Apify platform compute is billed separately per your plan. ### Tips - Feed a list of your portfolio domains and schedule a weekly run to catch upcoming expirations via `daysUntilExpiry`. - Use `domainAgeDays` to flag newly registered domains in fraud/abuse investigations. ### FAQ, disclaimers, and support **Why is registrant contact info missing?** Most registrars redact personal contact fields under GDPR and ICANN policy. This Actor returns only publicly published data. **Why did a lookup fail?** Some TLDs use non-standard WHOIS servers or rate-limit queries. Try again or reduce the number of domains per run. **Found a bug or want a feature?** Use the **Issues** tab. Custom solutions available. # Actor input Schema ## `domains` (type: `array`): One or more bare domains to look up (e.g. example.com). Max 10 per run. Protocol and www. are stripped automatically. ## `domain` (type: `string`): Alternative to the list above — a single domain to look up. ## `follow` (type: `integer`): How many WHOIS referral servers to follow for richer data (1-3). Higher = more detail, slightly slower. ## Actor input object example ```json { "domains": [ "example.com" ], "follow": 2 } ``` # Actor output Schema ## `dataset` (type: `string`): No description # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "domains": [ "example.com" ], "follow": 2 }; // Run the Actor and wait for it to finish const run = await client.actor("ntriqpro/whois-domain-lookup").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
