They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows. 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/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.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/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 RDAP Lookup - Free Beta Look up public domain-registration metadata from authoritative RDAP services without WHOIS scraping, browser automation, logins, API keys, or proxies. The Actor accepts 1-25 bare domains, discovers each TLD's service through IANA's bootstrap registry, and returns normalized registrar, lifecycle, status, nameserver, entity, DNSSEC, notice, and source fields. ### Official basis and usage boundary - IANA publishes the official [RDAP bootstrap registry for the domain name space](https://www.iana.org/assignments/rdap-dns/rdap-dns.xhtml) and links its machine-readable [`dns.json`](https://data.iana.org/rdap/dns.json). The registry references RFC 9224 for authoritative service discovery. - IANA's linked [licensing terms](https://www.iana.org/help/licensing-terms) place applicable protocol-registry rights under CC0, while explicitly preserving third-party, trademark, patent, privacy, and data-protection rights and providing the registry without warranty. - ICANN describes RDAP as the definitive gTLD registration-data source since 28 January 2025 and explains that responses come from registry operators and registrars. Its [RDAP lookup FAQ](https://lookup.icann.org/en/faq) warns that public fields vary, personal data can be redacted, and returned data can be inaccurate or unavailable. - Most importantly, ICANN's [Using Domain Name Registration Data](https://www.icann.org/resources/pages/domain-name-registration-data-2023-11-02-en) page says RDDS may be used for legal purposes, but not to enable mass unsolicited commercial advertising or solicitation, and not for high-volume automated registry/registrar queries except as needed to manage domains. This is therefore a low-volume metadata lookup tool, not a lead-list generator, contact harvester, bulk monitoring service, or permission to bypass a registry's notices. A commercial use is not automatically prohibited, but it must be lawful, low-volume, compatible with the specific authoritative service's notices, and unrelated to unsolicited solicitation. The Actor deliberately omits vCard names, email addresses, phone numbers, and postal addresses from generic entities. #### Live source verification Verified on 18 July 2026: - IANA bootstrap returned HTTP 200, `application/json`, a 24-hour cache directive, and publication timestamp `2026-07-14T22:00:03Z`. - IANA mapped `.com` to `https://rdap.verisign.com/com/v1/` and `.org` to `https://rdap.publicinterestregistry.org/rdap/`. - Authoritative lookups for `example.com` and `iana.org` both returned HTTP 200 with `application/rdap+json`, registrars, registration/expiration dates, statuses, nameservers, and signed DNSSEC delegation data. Availability and returned fields can change. Each output includes the bootstrap publication timestamp and exact final RDAP URL for provenance. ### Input ```json { "domains": ["example.com", "iana.org", "bücher.de"] } ```` `domains` is required and accepts 1-25 unique names. The Actor: - normalizes case, a single trailing root dot, and Unicode IDNs to ASCII A-labels; - rejects URLs, paths, query strings, fragments, credentials, ports, IP addresses, single-label names, invalid labels, control characters, and duplicates after normalization; - rejects unknown input fields instead of silently ignoring them. ### Dataset output Each successful lookup produces one `domain_rdap_record`: ```json { "type": "domain_rdap_record", "domain": "example.com", "unicodeName": "example.com", "handle": "2336799_DOMAIN_COM-VRSN", "registrar": { "name": "RESERVED-Internet Assigned Numbers Authority", "handle": "376", "ianaId": "376", "rdapUrl": null }, "createdAt": "1995-08-14T04:00:00.000Z", "updatedAt": "2026-01-16T18:26:50.000Z", "expiresAt": "2026-08-13T04:00:00.000Z", "status": ["client delete prohibited", "client transfer prohibited"], "nameservers": ["elliott.ns.cloudflare.com", "hera.ns.cloudflare.com"], "entities": [ { "handle": "376", "roles": ["registrar"], "publicIds": [{ "type": "IANA Registrar ID", "identifier": "376" }] } ], "secureDNS": { "zoneSigned": null, "delegationSigned": true, "maxSigLife": null, "dsData": [{ "keyTag": 2371, "algorithm": 13, "digestType": 2, "digest": "..." }], "keyData": [] }, "notices": [], "bootstrapUrl": "https://data.iana.org/rdap/dns.json", "bootstrapPublication": "2026-07-14T22:00:03.000Z", "rdapBaseUrl": "https://rdap.verisign.com/com/v1/", "rdapUrl": "https://rdap.verisign.com/com/v1/domain/example.com", "fetchedAt": "2026-07-18T13:55:47.000Z" } ``` Lifecycle dates use only the exact RDAP event actions `registration`, `last changed`, and `expiration`; the server's separate “last update of RDAP database” event is not misreported as a domain update. Missing or redacted values remain `null` or empty arrays. ### Network and abuse boundaries - The only bootstrap URL is the fixed IANA HTTPS URL. It is fetched once per process and safely cached in memory for at most 24 hours. - A TLD service must come from that validated bootstrap document and use HTTPS. HTTP-only entries fail with `NO_SECURE_RDAP_SERVICE`; the Actor never downgrades to plaintext. - Dynamic service and redirect URLs reject credentials, non-443 ports, fragments, unexpected domain paths, IP literals, and DNS resolutions to loopback, private, link-local, carrier-grade NAT, documentation, multicast, or reserved addresses. - Redirects are manual, revalidated, and capped at three. - Global domain concurrency is three. Requests to the same authority are serialized with at least one second between starts. - Bootstrap responses are capped at 1 MB and 15 seconds. RDAP responses are capped at 2 MB and 20 seconds. - Each request has at most one retry. HTTP 429 honors `Retry-After` with a conservative five-second fallback; network, 408, and 5xx failures use bounded backoff. A 404 is not retried. - Entity traversal, public IDs, DNSSEC arrays, notices, notice text, and error messages are all bounded before storage. These controls reduce accidental load and SSRF exposure; they do not authorize repeated schedules or bulk extraction. Respect notices returned in every record. ### Partial failures Successful domains are stored even when another domain fails. `OUTPUT` contains `success`, `partial`, or `failed`, bootstrap provenance, requested/succeeded/failed counts, effective limits, and bounded failures such as: - `UNSUPPORTED_TLD` - `NO_SECURE_RDAP_SERVICE` - `DOMAIN_NOT_FOUND` - `RDAP_LOOKUP_FAILED` - `BOOTSTRAP_FAILED` If every lookup fails, the summary is written and the Actor run fails. ### Local verification Node.js 22 or newer is required. ```bash npm ci npm test npm run check npm run live-smoke ``` The live smoke fetches the current IANA bootstrap and independently verifies `.com` (`example.com`) and `.org` (`iana.org`) against their authoritative RDAP services. ### Guarded FREE release The default command is a local dry run and never calls Apify: ```bash npm run release ``` The exact executing command is: ```bash APIFY_TOKEN='apify_api_...' \ CONFIRM_PUBLISH_FREE_BETA='domain-rdap-lookup-free-beta' \ npm run release:execute ``` The executing script creates or updates only the private Actor `domain-rdap-lookup-free-beta`, enforces `LIMITED_PERMISSIONS`, builds without cache, runs and validates the two-TLD cloud smoke while private, rechecks the exact build and FREE state, and only then makes it public. It refuses to replace an already-public target. Publication verification failures trigger a best-effort, verified rollback to private. Every outgoing API body is recursively blocked if it contains a `pricingInfos` key. The script never creates or updates pricing information; any observed non-FREE pricing stops the release. # Actor input Schema ## `domains` (type: `array`): One to 25 bare domain names.
