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 **DNS Record & Whois Lookup** instantly retrieves all DNS records and WHOIS registration data for any domain. Whether you're auditing infrastructure, verifying a migration, checking domain ownership, or building bulk domain intelligence pipelines — this tool gives you everything in one row per domain. Unlike tools that only check one or two record types, this actor queries all 13 DNS record types (A, AAAA, MX, CNAME, TXT, NS, PTR, SOA, SRV, CAA, NAPTR, DS, TLSA) and pairs each domain with full WHOIS data — registrar, registrant, admin contacts, dates, status, and nameservers — in a single run. [![Watch the video](https://img.youtube.com/vi/uNXSXheJZ3w/maxresdefault.jpg)](https://www.youtube.com/watch?v=uNXSXheJZ3w) **Use cases include:** - **Domain audits** — check all DNS records and registration details for hundreds or thousands of domains at once - **Migration verification** — confirm DNS records are correctly set after a domain or hosting migration - **Email deliverability checks** — verify MX and TXT (SPF/DKIM/DMARC) records are correctly configured - **Security audits** — identify missing CAA records, check DNSSEC (DS/TLSA), and detect misconfigurations - **Domain expiry monitoring** — bulk-check WHOIS expiry dates to catch domains about to lapse - **Ownership & contact research** — look up registrant and admin contact details for any domain list - **Competitive research** — quickly look up the full DNS and registration profile behind any list of domains --- ### Features - **13 DNS record types** — A, AAAA, MX, CNAME, TXT, NS, PTR, SOA, SRV, CAA, NAPTR, DS, TLSA — all checked automatically - **Full WHOIS data** — registrar, IANA ID, abuse contacts, dates, status, nameservers, registrant, and admin contacts - **SOA flattened** — SOA record returned as a single readable string (mname, rname, serial, refresh, retry, expire, minttl) - **DS & TLSA with silent fallback** — DNSSEC and DANE records attempted; silently skipped if not supported or not present - **URL-tolerant input** — input `https://www.example.com/page` and it automatically extracts `example.com` - **Deduplication** — duplicate domains in input are silently deduplicated before processing - **Bulk-ready** — handles 1 to 50,000+ domains efficiently with concurrency control and budget capping - **Minimal dependencies** — uses Node.js built-in `dns/promises` for DNS; `whoiser` for WHOIS parsing --- ### How to Use #### Input | Field | Type | Required | Description | |---|---|---|---| | `domains` | String list | Yes | Domains to check (e.g. `example.com`). URLs like `https://www.example.com/page` are automatically cleaned to bare domain. | **Example input:** ```json { "domains": [ "onescales.com" ] } ```` #### Output One row per domain.
