# Check whether a list of domains is available

**Use case:** 

Bulk domain availability check for a short list of full domain names, using official registry RDAP (the modern WHOIS). Returns available or registered, plus registrar and expiry for taken names. $0.001 per checked domain; $1 per 1,000; invalid inputs and errors free.

## Input

  "domains": [
    "google.com",

## FAQ

### What does available mean?

The registry has no record of the name. Premium, reserved or blocked names can still cost more or be unregistrable. Confirm at a registrar.

### Does this return the owner's email or phone?

No. Only registry and registrar facts are returned. No personal contact data.

### How much does this example cost?

Three successful checks cost $0.003. The Actor price is $1.00 per 1,000 checked domains. Invalid inputs and errors are free.

## About this Actor

This example demonstrates how to use [Bulk Domain Availability Checker: WHOIS, RDAP & Expiry](https://apify.com/hillcountrybots/domain-availability-checker.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

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 full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/hillcountrybots/domain-availability-checker.md

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`).
