## Pricing

from $150.00 / 1,000 per free domain suggesteds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. 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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# 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/<id>/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/<id>/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.

# Actor input Schema

## `domains` (type: `array`):

Full domains ("example.com") are checked as-is. Bare labels ("example") are expanded across the TLDs below. Ex.: \["mycoolstartup", "google.com", "example"].

## `tlds` (type: `array`):

TLDs used to expand bare labels (ignored for full domains). All listed TLDs support RDAP for accurate verdicts. Ex.: \["com", "io", "ai"].

## `suggestAlternatives` (type: `boolean`):

When on, every TAKEN domain gets AI-generated brandable alternatives that we verify are actually available. Billed per available idea returned. Off keeps the run 100% free.

## `maxSuggestions` (type: `integer`):

How many verified-available alternatives to return per taken domain (only when AI name ideas is on). Ex.: 5.

## `nameStyle` (type: `string`):

Steers the style of the AI name ideas (only when AI name ideas is on).

## `emails` (type: `array`):

Optional. Email addresses to send the branded HTML report to. Ex.: \["you@company.com"].

## MCP server setup

```json

    "mcpServers": {

            "url": "https://mcp.apify.com/?tools=fetch-actor-details,acmegen.ai/free-domains-checker-ai"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
