## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper 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

## Domain Expiration Tracker — Registrar, Dates & Status

Check registration date, expiration date, days until expiry, registrar,
nameservers, and status for a list of domains — via the official RDAP
protocol, the modern IANA-standardized successor to WHOIS.

Built for IT teams managing a domain portfolio (catching renewals before
they lapse), brand/security teams watching for lapsed-domain takeover
risk, and anyone checking whether a domain is available.

### Input

```json
{
  "domains": ["google.com", "thisdomaindefinitelydoesnotexist12345xyz.com"]
}
```

| Field | Type | Description |
|---|---|---|
| `domains` | array of strings | Domains to check, without protocol or `"www."`. One lookup is billed per domain. |

### Output

One record per domain:

```json
{
  "domain": "google.com",
  "registered": true,
  "registrar": "MarkMonitor Inc.",
  "creationDate": "1997-09-15T04:00:00Z",
  "expirationDate": "2028-09-14T04:00:00Z",
  "daysUntilExpiration": 762,
  "lastChangedDate": "2019-09-09T15:39:04Z",
  "statuses": ["client delete prohibited", "client transfer prohibited", "client update prohibited"],
  "nameservers": ["NS1.GOOGLE.COM", "NS2.GOOGLE.COM", "NS3.GOOGLE.COM", "NS4.GOOGLE.COM"],
  "rdapUrl": "https://rdap.verisign.com/com/v1/domain/google.com"
}
```

An unregistered/available domain returns `"registered": false` with the
other fields `null` — still billed once, since a completed availability
check is the result either way.

### How it works

Direct calls to the official [RDAP](https://www.icann.org/rdap) protocol:
looks up the correct registry server per domain via the [IANA RDAP
bootstrap registry](https://data.iana.org/rdap/dns.json), then queries it
directly. No proxy, no key, no scraping.

**Coverage note:** RDAP is mandatory for ICANN-accredited gTLDs (`.com`,
`.net`, `.org`, `.info`, `.dev`, `.app`, and most others) but optional for
ccTLDs — a handful (e.g. `.co`, `.us`) don't publish an RDAP server yet
and will return a clear error instead of a result.

### Pricing note

Billed per **domain checked**, not per field returned — one charge per
domain whether it's registered or available.

# Actor input Schema

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

Domains to check, without protocol or "www." (e.g. "example.com"). One lookup is billed per domain. Not all TLDs support RDAP — mainstream gTLDs (.com, .net, .org, .info, .dev, .app, etc.) are well covered; some ccTLDs (e.g. "co", "us") are not.

## Actor input object example

```json
{
  "domains": [
    "google.com"
  ]
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "domains": [
        "google.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("m_ctim/domain-expiration-tracker").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "domains": ["google.com"] }

# Run the Actor and wait for it to finish
run = client.actor("m_ctim/domain-expiration-tracker").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "domains": [
    "google.com"
  ]
}' |
apify call m_ctim/domain-expiration-tracker --silent --output-dataset

```

## MCP server setup

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

```

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).
