# Free Domain Checker AI: Bulk Availability + AI Name Ideas (`acme-ai/free-domains-checker-ai`) Actor Check domain availability in bulk for free (DNS + RDAP): registered or available, with registrar, expiry, nameservers and status. When a domain is taken, optionally get AI-generated brandable name ideas that are verified available. Export to CSV or JSON. - **URL**: https://apify.com/acme-ai/free-domains-checker-ai.md - **Developed by:** [Acme AI](https://apify.com/acme-ai) (community) - **Categories:** Developer tools, E-commerce, SEO tools - **Stats:** 1 total users, 0 monthly users, 100.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing from $150.00 / 1,000 per free domain suggesteds This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage. Since this Actor supports Apify Store discounts, the price gets lower 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 ## Free Domain Checker AI: Bulk Availability + AI Name Ideas Check domain availability in **bulk, for free**. Paste full domains or bare names, and get a clear verdict per domain - **available, taken, or unknown** - with registrar, expiry, nameservers and status. When a domain is taken, optionally turn on **AI name ideas**: the actor generates brandable alternatives and only returns the ones it **verified are actually available**. - **Free base check** - bulk availability via DNS + RDAP. No API key, no setup, no per-domain fee. - **Bare label expansion** - pass `mycoolstartup` and check it across `.com`, `.io`, `.ai`, and more. - **Honest verdicts** - registered domains are `taken`, free ones are `available`, and TLDs without a public registry are `unknown` (never a false "available"). - **AI name ideas (premium, opt-in)** - for every taken domain, get verified-available brandable alternatives. Billed only per available idea actually returned. - **Branded HTML report** - a shareable report URL per run, plus optional email delivery. - **One row per domain** - flat output, export to CSV or JSON. ### Free vs premium | | Free | Premium (AI name ideas) | |---|---|---| | Bulk availability (DNS + RDAP) | Yes | Yes | | Registrar, expiry, nameservers, status | Yes | Yes | | Branded report + email | Yes | Yes | | Brandable alternatives for taken domains | - | Yes (verified available) | | Cost | Free | Per available idea returned | Turn premium on with `suggestAlternatives: true`. With it off, the run is 100% free. ### Input | Field | Type | Description | |---|---|---| | `domains` | array (required) | Full domains (`example.com`) checked as-is, or bare labels (`example`) expanded across `tlds`. Up to 200. | | `tlds` | array | TLDs used to expand bare labels. Default: `com, net, org, io, ai, app, dev`. | | `suggestAlternatives` | boolean | Premium. When taken, return verified-available AI brandable alternatives. Default `false`. | | `maxSuggestions` | integer | Ideas to return per taken domain (1-15). Default `5`. | | `nameStyle` | string | `auto`, `short`, `brandable`, `compound`, or `playful`. Default `auto`. | | `emails` | array | Optional. Send the branded HTML report to these addresses. | ```json { "domains": ["mycoolstartup", "google.com", "example"], "tlds": ["com", "io", "ai"], "suggestAlternatives": false } ```` ### How the verdict is determined 1. **DNS fast-path** - if a domain resolves nameservers, it is definitely registered (`taken`). 2. **RDAP authority** - otherwise the actor queries the public RDAP registry. A "not found" from the authoritative server means `available`; a `200` means `taken` (with registrar, dates, nameservers and status). TLDs that have no public RDAP registry return `unknown` - the actor never guesses. Up to 200 domain checks per run (bare labels count after expansion). ### Output One record per checked domain. AI name ideas are nested under `suggestions`. ```json [ { "domain": "google.com", "label": "google", "tld": "com", "available": false, "status": "taken", "source": "rdap", "registrar": "MarkMonitor Inc.", "createdAt": "1997-09-15T04:00:00Z", "expiresAt": "2028-09-14T04:00:00Z", "lastChangedAt": "2019-09-09T15:39:04Z", "nameservers": ["ns1.google.com", "ns2.google.com", "ns3.google.com", "ns4.google.com"], "domainStatus": ["client delete prohibited", "client transfer prohibited", "client update prohibited"], "suggestions": [ { "name": "gogliax.com", "available": true, "tld": "com" }, { "name": "goguno.com", "available": true, "tld": "com" }, { "name": "gogarao.com", "available": true, "tld": "com" } ], "suggestionsAvailableCount": 3, "reportUrl": "https://api.apify.com/v2/key-value-stores//records/report-...?signature=...", "checkedAt": "2026-06-11T12:00:00.000Z", "error": null }, { "domain": "mycoolstartup.io", "label": "mycoolstartup", "tld": "io", "available": true, "status": "available", "source": "rdap", "registrar": null, "createdAt": null, "expiresAt": null, "lastChangedAt": null, "nameservers": null, "domainStatus": null, "suggestions": [], "suggestionsAvailableCount": 0, "reportUrl": "https://api.apify.com/v2/key-value-stores//records/report-...?signature=...", "checkedAt": "2026-06-11T12:00:00.000Z", "error": null } ] ``` `status` is `available`, `taken`, or `unknown` (a TLD without a public RDAP registry). `suggestions` is `null` on a free run and an array (possibly empty) when AI name ideas are on. ### API integration #### Batch (run and get the dataset) ```bash curl -X POST "https://api.apify.com/v2/acts/acme-ai~free-domains-checker-ai/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \ -H "Content-Type: application/json" \ -d '{"domains":["google.com","example","mycoolstartup"],"suggestAlternatives":false}' ``` #### Standby (real-time HTTP) ```bash curl -X POST "https://acme-ai--free-domains-checker-ai.apify.actor/check" \ -H "Authorization: Bearer YOUR_APIFY_TOKEN" \ -H "Content-Type: application/json" \ -d '{"domains":["mycoolstartup"],"tlds":["com","io","ai"],"suggestAlternatives":true,"maxSuggestions":5}' ``` The standby endpoint returns the same array directly in the HTTP response. ### Related actors - [AI Google Ads Generator](https://apify.com/acme-ai~ai-google-ads-generator) - [AI LinkedIn Ads Generator](https://apify.com/acme-ai~ai-linkedin-ads-generator) # Actor input Schema ## `domains` (type: `array`): Full domains ("example.com") are checked as-is.
