# Domain WHOIS & Age Checker: Bulk RDAP Registration Data (`scrapemint/domain-whois-checker`) Actor Check domain registration data in bulk: registrar, creation and expiry dates, age, status locks, nameservers, DNSSEC, and whether a domain is registered at all. Uses RDAP, the official registry JSON protocol, so results come straight from the source. Keyless, no browser, no rate walls. - **URL**: https://apify.com/scrapemint/domain-whois-checker.md - **Developed by:** [Ken M](https://apify.com/scrapemint) (community) - **Categories:** Lead generation, Business - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing Pay per usage This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

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 ## Domain WHOIS & Age Checker: Bulk RDAP Registration Data Check any list of domains and get back who registered them, when, through which registrar, and when they expire. This actor uses RDAP, the official JSON successor to WHOIS served by the registries themselves, so the data comes straight from the source with no key, no login, no browser, and no rate walls. Paste domains or URLs, get one clean JSON row per domain. Built for lead scoring (domain age is a trust signal), expired domain hunting, fraud and phishing triage, portfolio expiry monitoring, and bulk availability checks. ### What you get One row per domain, with: - `domain`, `registered` (false means the registry says it is not registered) - `registrar`, `registrarIanaId` - `createdAt`, `updatedAt`, `expiresAt` - `ageDays`, `ageYears`, `daysUntilExpiry` - `status` (transfer and delete locks, holds) - `nameservers`, `dnssec` - `rdapSource` (which registry answered) A domain registered last week claiming ten years in business is a fraud signal. A domain expiring in 20 days with no transfer lock is an acquisition target. A lead list sorted by domain age puts the established businesses on top. ### Input - `domains` (one per line; full URLs are fine, protocol and path are stripped) - `maxDomains` (default 500, up to 2000) ### Example input ```json { "domains": ["stripe.com", "shopify.com", "openai.com"] } ```` ### Example output ```json { "domain": "stripe.com", "registered": true, "registrar": "MarkMonitor Inc.", "registrarIanaId": "292", "createdAt": "1995-08-08T04:00:00Z", "expiresAt": "2027-08-07T04:00:00Z", "ageDays": 11294, "ageYears": 30.9, "daysUntilExpiry": 393, "status": ["client delete prohibited", "client transfer prohibited", "server delete prohibited"], "nameservers": ["ns1.stripe.com", "ns2.stripe.com"], "dnssec": false, "rdapSource": "rdap.verisign.com" } ``` ### Uses - Lead scoring: enrich lead lists with domain age and registrar; older domains are established businesses - Fraud and phishing triage: newly created domains behind suspicious emails or lookalike brands - Expired domain hunting: check expiry dates and lock status across candidate lists in bulk - Portfolio monitoring: schedule a run over your own domains and alert on approaching expiry - Bulk availability: `registered: false` rows are names you can still register - Chain with the Newly Registered Domain Leads and Website Contact Scraper actors for a full domain prospecting pipeline ### Pricing Pay per answer. A row is charged only when the registry gave a definitive result: full registration data or an authoritative not-registered response. Failed lookups and TLDs without RDAP support cost nothing. The first 2 rows of every run are free so you can validate output before you scale up. ### Notes - Lookups go directly to each TLD's registry using the IANA RDAP bootstrap, with rdap.org as fallback; com, net, org and most gTLDs have full coverage. - Some country TLDs do not publish RDAP yet; those rows come back with `error: "unsupported_tld"` and are not charged. - Registrant name and email are redacted by most registries since GDPR; this actor returns registration facts (dates, registrar, status, nameservers), which registries still publish for every domain. # Actor input Schema ## `domains` (type: `array`): Domains or URLs to check, one per line. Protocols, paths and www. are stripped automatically. ## `maxDomains` (type: `integer`): Cap on domains checked. Controls total cost. ## Actor input object example ```json { "domains": [ "stripe.com", "shopify.com", "openai.com" ], "maxDomains": 500 } ``` # 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": [ "stripe.com", "shopify.com", "openai.com" ] }; // Run the Actor and wait for it to finish const run = await client.actor("scrapemint/domain-whois-checker").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 📖?
