# Domain Availability Checker – Bulk Domain Name Checker (`rowfeed/domain-availability-checker`) Actor

Check if domains are available to register, in bulk, straight from the registries. Paste domains or just a name to try it in .com, .io, .ai and any other TLD. Taken domains come with registrar, creation and expiry date. $0.40 per 1,000.

## Pricing

from $0.40 / 1,000 domain checkeds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Domain Availability Checker – Bulk Domain Name Checker

Check if domains are free to register, one or 50,000 at once. The answer comes from each registry's own RDAP service (the official successor to WHOIS), not from a reseller's cache. Paste:

- **Domains** such as `example.com` or `shop.co.uk`. URLs, subdomains and email addresses are reduced to the domain.
- **Plain names** such as `mybrand`. A name is tried in every TLD you choose: .com, .net, .org, .io, .ai, .co, .app and .dev by default, or any others (.no, .de, .shop, .co.uk ...).

For each domain you get:

- **available**: true or false, and a `status`: `available`, `registered` or `likely_available`.
- For taken domains: **registrar**, **creation date**, **expiry date**, days to expiry, name servers and the registry status. `pending delete` or `redemption period` means the domain may soon be free again.

Built for naming a startup or product, domain investors, brand protection (which spellings of your name are still free) and agencies checking client domains.

### Example output rows

```json
{"domain": "rowfeedlabs.io", "name": "rowfeedlabs", "tld": "io", "available": true, "status": "available", "checked_via": "registry RDAP"}
{"domain": "apify.com", "name": null, "tld": "com", "available": false, "status": "registered", "checked_via": "registry RDAP",
 "registrar": "...", "created": "2015-...", "expires": "...", "days_to_expiry": 400,
 "registry_status": ["client delete prohibited", "client transfer prohibited"], "name_servers": ["..."]}
```

### How to use

1. Click **Try for free** (or **Start**) at the top of this page to open the input form.
2. Fill in **Domains or names**. Up to 50,000 domains (example.com) or plain names (mybrand). The form comes with a working example, so you can also run it as it is.
3. Optional: adjust **TLDs to try for plain names**. Every field has a sensible default.
4. Click **Start** and wait for the run to finish.
5. Download the results as Excel, CSV or JSON from the **Output** tab, or get them through the Apify API, a schedule or an integration (Make, Zapier, Google Sheets ...).

### Pricing

Pay per event, no subscription:

- **$0.0004 per domain** checked ($0.40 per 1,000).
- $0.001 per run start.

Checks that get no answer, and text that is not a domain or name, are free. Works on the free Apify plan.

### Input

| Field | What it does |
|---|---|
| `domains` | Domains or plain names, up to 50,000. `Acme Corp` becomes the name `acmecorp`. |
| `tlds` | Endings to try for plain names, e.g. `com`, `io`, `no`, `co.uk`. Leave empty for the 8 defaults. |

### Good to know

- **Available means not registered at the registry.** Some names are reserved or sold as premium by the registry at a higher price, and some country TLDs (.no, .eu, .us ...) only sell to local people or companies. Your registrar shows the final price when you buy.
- A few TLDs publish no RDAP (for example .de, .co, .eu, .es, .it, .se, .jp). There the check uses DNS: a domain with name servers is `registered`, one not found in DNS is `likely_available`, because a registered domain without name servers looks the same.
- When the registry has no record yet but the domain already has name servers (registered minutes ago), it is reported as registered.

# Actor input Schema

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

Up to 50,000 domains (example.com) or plain names (mybrand). A plain name is tried in every TLD below. URLs, subdomains and email addresses are reduced to the domain. Duplicates are checked once.

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

Endings tried for each plain name, e.g. com, io, ai, no, co.uk. Leave empty for com, net, org, io, ai, co, app and dev. Full domains are checked as they are.

## MCP server setup

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

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).
