## Pricing

from $5.00 / 1,000 results

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.

## Domain Checker Tool: Instant Domain Availability Lookup by Extension

Check whether a specific domain name is registered or free to buy. Input a full domain like `example.com` or `mybrand.io` and get a clean availability result back. Leave off the extension and it defaults to `.com`. This actor runs on a Pay Per Result model — you only pay for the domains you actually check.

### Pricing

This actor uses Pay Per Result pricing. There are no upfront charges. Each successful domain lookup counts as one result. Run 5 domains and pay only for those 5, not a flat fee. Costs stay predictable whether you run a single check or a full batch.

### Use cases

- **Brand name validation**: confirm your chosen domain is free before you build around it.
- **Quick .com checks**: test a list of brand ideas against `.com` without extra configuration.
- **Extension-specific lookup**: need to know if `mybrand.io` or `mybrand.dev` is taken? Input the full domain and get an exact answer.
- **Startup naming workflow**: run a shortlist of potential names and filter results by `available: true`.
- **Pre-purchase auditing**: verify domain status before placing registration orders.

### How is this different from the Bulk Domain Checker?

The Bulk Domain Checker scans a base name across all 80+ supported TLDs and returns one record per extension. This actor does the opposite: give it a full domain and it returns exactly one result. No extra TLDs, no noise.

### Input

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `domains` | array | — | Full domain names to check (e.g., `example.com`, `brand.io`). If you omit the TLD (e.g., `example`), the actor checks `example.com` by default. |
| `timeoutSecs` | integer | 600 | Actor timeout in seconds. |
| `proxyConfiguration` | object | Datacenter (Anywhere) | Optional proxy settings. |

> **Default TLD:** If you enter a domain without an extension (e.g., `mybrand`), the actor automatically checks `mybrand.com`.

#### Example input

```json
{
    "domains": [
        "kawsarlog.com",
        "kawsarlog.io",
        "mybrand"
    ],
    "proxyConfiguration": {
        "useApifyProxy": true
    }
}
```

`mybrand` above is treated as `mybrand.com`.

### What data does this actor return?

One dataset record per domain input:

```json
{
  "domain": "kawsarlog.com",
  "isRegistered": true,
  "available": false,
  "label": "kawsarlog",
  "tld": "com"
}
```

| Field | Type | Description |
|-------|------|-------------|
| `domain` | string | The exact domain that was checked. |
| `isRegistered` | boolean | True if the domain is already taken. |
| `available` | boolean | True if the domain is free to register. Always the inverse of `isRegistered`. |
| `label` | string | The base name without the extension. |
| `tld` | string | The extension that was checked. |

### How it works

1. The actor reads your domain list and removes duplicates.
2. For each domain, it extracts the base name and the TLD. If no TLD is found, it defaults to `.com`.
3. It queries the Instant Domain Search API for only that specific TLD — no unnecessary requests.
4. The result is filtered to the exact TLD, structured, and pushed to the dataset.
5. If a domain fails to resolve, it records a generic error without stopping the rest of the run.

### FAQ

**What happens if I enter just `mybrand` with no extension?**
The actor treats it as `mybrand.com`. If you need a different extension, include it explicitly (e.g., `mybrand.io`).

**Can it check multiple different extensions at once?**
Yes. Add them as separate entries: `["mybrand.com", "mybrand.io", "mybrand.net"]`. Each gets its own record.

**What happens when a domain check fails?**
The actor writes a record with `isRegistered: null`, `available: null`, and an `error` field. The run continues for all remaining domains.

### Integrations

Connect this actor with other tools using [Apify integrations](https://apify.com/integrations). Push results to Google Sheets, send Slack alerts when a domain becomes available, or automate registration workflows in Make or Zapier. Use [webhooks](https://docs.apify.com/integrations/webhooks) to fire actions when a run completes.

# Actor input Schema

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

List of full domain names to look up (e.g., example.com or example.net). If you omit the extension (e.g., just example), the actor defaults to checking example.com.

## `timeoutSecs` (type: `integer`):

Maximum time for the actor to run.

## `proxyConfiguration` (type: `object`):

Select proxies to use for requests. Helps avoid IP blocking and rate limits. Datacenter proxies are fastest; Residential proxies are harder to detect.

## Actor input object example

```json
{
  "domains": [
    "kawsarlog.com",
    "example.net"
  ],
  "timeoutSecs": 600,
  "proxyConfiguration": {
    "useApifyProxy": true
  }
}
```

## CLI example

```bash
echo '{
  "domains": [
    "kawsarlog.com"
  ],
  "proxyConfiguration": {
    "useApifyProxy": true
  }
}' |
apify call kawsar/domain-cheker-tool --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,kawsar/domain-cheker-tool"
        }
    }
}

```

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).
