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 / RDAP Domain Lookup Look up WHOIS and RDAP registration data in bulk, including registrar, expiry dates, domain status flags, nameservers, DNSSEC, contact summaries, abuse contacts, and optional raw RDAP JSON. Use it for domain portfolio monitoring, SEO aged-domain research, brand protection, merchant risk checks, cybersecurity OSINT, and developer-friendly domain intelligence exports. ### At a glance - **Bulk domain lookup**: Paste domains, hostnames, or URLs and get one normalized output row per unique input domain. - **Registration details**: Export registrar, IANA ID, creation date, update date, expiry date, statuses, and nameservers. - **Risk and compliance context**: Review abuse contacts, DNSSEC delegation status, notices, and lookup errors. - **Raw RDAP option**: Include the full RDAP JSON payload when you need auditability or custom downstream parsing. - **API-ready output**: Download CSV/JSON/Excel exports or call the actor from Apify API, MCP, Make, Zapier, or agents. ### Ready-to-run examples Open an example, review the input, and run it as-is or adjust the domains: - **[Domain RDAP expiry check](https://apify.com/fetch_cat/whois-rdap-domain-lookup/examples/domain-rdap-expiry-check)**: Check renewal and expiry dates for public domains. - **[Bulk WHOIS registrar audit](https://apify.com/fetch_cat/whois-rdap-domain-lookup/examples/bulk-whois-registrar-audit)**: Compare registrar names and IANA IDs across a domain list. - **[Brand protection domain check](https://apify.com/fetch_cat/whois-rdap-domain-lookup/examples/brand-protection-domain-check)**: Review domains that may matter for brand monitoring. - **[SEO aged domain research](https://apify.com/fetch_cat/whois-rdap-domain-lookup/examples/seo-aged-domain-research)**: Export creation and expiry context for aged-domain screening. - **[RDAP raw JSON export](https://apify.com/fetch_cat/whois-rdap-domain-lookup/examples/rdap-raw-json-export)**: Include full RDAP payloads for auditing or custom parsing. ### What can it do? WHOIS / RDAP Domain Lookup normalizes each input, calls public RDAP endpoints, and saves structured domain registration records to an Apify dataset. - **Normalize inputs**: Accept bare domains, hostnames, or URLs such as `example.com`, `www.example.com/path`, or `https://example.com`. - **Fetch RDAP records**: Query direct registry RDAP endpoints for common TLDs and fall back to `rdap.org`. - **Save success and error rows**: Keep invalid domains, unsupported TLDs, timeouts, and registry failures visible in the dataset. - **Control reliability**: Tune concurrency, retry count, and request timeout for registry rate limits. - **Export clean records**: Use fields for registrar audits, expiry monitoring, nameserver inventories, risk checks, and dashboards. ### Common workflows - **Domain portfolio expiry monitoring**: Track `expiresAt`, `registrarName`, `statuses`, and `nameservers`. - **Brand protection**: Check suspicious or lookalike domains for registrar, dates, and status flags. - **SEO aged-domain research**: Compare domain creation dates, status flags, nameservers, and raw RDAP records. - **Merchant or vendor risk checks**: Add domain age and registrar context to CRM, onboarding, or risk-review workflows. - **Security OSINT**: Export RDAP records for domains related to investigations, phishing reports, or infrastructure mapping. ### Output fields The actor returns one dataset row per unique input domain. | Field | Description | | --- | --- | | `inputDomain` | Original input string | | `normalizedDomain` | Normalized ASCII domain used for lookup | | `lookupUrl` | RDAP endpoint URL used for the lookup | | `success` | Whether the lookup returned a usable RDAP record | | `error` | Error message for invalid or failed lookups | | `registryDomainId` | Registry domain identifier when available | | `handle` | RDAP handle | | `ldhName` | LDH domain name | | `unicodeName` | Unicode domain name when available | | `registrarName` | Registrar name | | `registrarIanaId` | Registrar IANA ID | | `registrarUrl` | Registrar URL from RDAP entities | | `registrarAbuseEmail` | Registrar abuse email when published | | `registrarAbusePhone` | Registrar abuse phone when published | | `statuses` | RDAP domain status flags | | `createdAt` | Registration date when published | | `updatedAt` | Last update date when published | | `expiresAt` | Expiry date when published | | `nameservers` | Nameserver list | | `secureDnsDelegationSigned` | DNSSEC delegation status when available | | `contacts` | Summary of RDAP entities and contact roles | | `notices` | Registry notices and remarks | | `rawRdap` | Full RDAP JSON payload when `includeRawRdap` is enabled | ### Pricing The actor uses pay-per-event pricing, so cost is tied to the run and saved lookup rows. | Event | Price | Charged when | | --- | --- | --- | | `start` | `$0.005` per run | Once when the actor starts. | | `item` | BRONZE `$0.000070129` per saved domain lookup row | Each input domain row saved to the dataset. This is about `$0.07` per 1,000 saved rows on BRONZE, with lower per-row prices on higher Apify plans. | The `item` event is charged for saved lookup rows, including invalid-domain or RDAP-error rows, because those rows are still written to the dataset for auditability. Use a small domain list for your first run, review success and error rows, and then scale up. Exact live pricing is shown on the Apify actor page before you start a run. ### Input configuration | Setting | JSON key | Use it for | Example | | --- | --- | --- | --- | | Domains | `domains` | Required list of domains, hostnames, or URLs to normalize and look up. | `["example.com","https://apify.com"]` | | Include raw RDAP response | `includeRawRdap` | Save the complete RDAP JSON payload in `rawRdap`. | `true` | | Maximum concurrency | `maxConcurrency` | Number of domains to look up in parallel. | `3` | | Retry count | `retryCount` | Retries for temporary RDAP failures such as 429 or 5xx responses. | `2` | | Request timeout seconds | `timeoutSecs` | Per-domain RDAP request timeout. | `20` | ### Example input ```json { "domains": [ "example.com", "iana.org", "https://apify.com" ], "includeRawRdap": true, "maxConcurrency": 3, "retryCount": 2, "timeoutSecs": 20 } ```` ### Example output ```json { "inputDomain": "example.com", "normalizedDomain": "example.com", "lookupUrl": "https://rdap.verisign.com/com/v1/domain/example.com", "success": true, "error": null, "registrarName": "RESERVED-Internet Assigned Numbers Authority", "registrarIanaId": "376", "registrarAbuseEmail": null, "statuses": ["client delete prohibited", "client transfer prohibited"], "createdAt": "1995-08-14T04:00:00Z", "updatedAt": "2024-08-14T07:01:39Z", "expiresAt": "2026-08-13T04:00:00Z", "nameservers": ["A.IANA-SERVERS.NET", "B.IANA-SERVERS.NET"], "secureDnsDelegationSigned": true, "contacts": [], "notices": [], "rawRdap": {} } ``` ### Search and data tips - **Use bare domains when possible**: URLs are accepted, but bare domains make input lists easier to review. - **Keep concurrency modest**: Registries can rate-limit RDAP traffic; increase `maxConcurrency` gradually. - **Turn off raw RDAP for small exports**: Set `includeRawRdap` to `false` when you only need flat fields. - **Check error rows**: Invalid domains, unsupported TLDs, and temporary registry failures are visible in `success` and `error`. - **Schedule expiry checks**: Run the same list weekly or monthly to monitor renewal windows. ### Limits and practical notes - RDAP coverage varies by TLD and registry. - Some registries redact contact details or do not publish dates in the same format. - `contacts` summarizes public RDAP entities; it is not a guaranteed lead/contact list. - WHOIS privacy and registry policy can leave registrar abuse or registrant fields empty. - This actor does not bypass access controls or query private registrar accounts. ### API usage #### cURL ```bash curl -X POST 'https://api.apify.com/v2/acts/fetch_cat~whois-rdap-domain-lookup/runs?token=YOUR_APIFY_TOKEN' \ -H 'Content-Type: application/json' \ -d '{"domains":["example.com","iana.org"],"includeRawRdap":false}' ``` #### Node.js ```js import { ApifyClient } from 'apify-client'; const client = new ApifyClient({ token: process.env.APIFY_TOKEN }); const run = await client.actor('fetch_cat/whois-rdap-domain-lookup').call({ domains: ['example.com', 'iana.org'], includeRawRdap: false }); const { items } = await client.dataset(run.defaultDatasetId).listItems(); console.log(items); ``` #### Python ```python from apify_client import ApifyClient import os client = ApifyClient(os.environ["APIFY_TOKEN"]) run = client.actor("fetch_cat/whois-rdap-domain-lookup").call(run_input={ "domains": ["example.com", "iana.org"], "includeRawRdap": False, }) items = client.dataset(run["defaultDatasetId"]).list_items().items print(items) ``` ### MCP and AI agents Use this actor from MCP-compatible tools through Apify MCP Server.
