Domain Availability Checker

Interactive intelligence tool

Run the check, then ship the workflow

Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.

1

Start with the live form

Enter a domain, URL, IP, email, or record and get a focused result without setup.

2

Review decision-ready signals

Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.

3

Automate the winning workflow

Use the request and response examples to turn a one-off check into an API call or recipe.

What this tool helps you decide

Each page is shaped around a practical operational question, not just a raw lookup.

Signal

See the current DNS, registration, security, pricing, or reputation evidence.

Context

Compare the result with related checks so the next move is easier to trust.

Action

Copy examples, open linked tools, or move into API documentation when you need scale.

Trust signals before you integrate

Transparent docs, authenticated requests, and visible reliability details make it easier to evaluate DomScan before you ship.

Uptime API artifacts

OpenAPI, Swagger, Postman, CLI, SDK, and MCP links are one click away.

API keys Protected access

Authenticated endpoints use API keys with clear credit costs before you call them.

Free allowance Sign Up for Free

Start with 10,000 monthly credits and upgrade only when usage grows.

Active Example Request

Start from the curl and HTTP samples, then map the parameters into your application code.

Key Features

Check Availability

We use the RDAP protocol (Registration Data Access Protocol) which queries official registry databases directly. This provides real-time, authoritative availability data with 99%+ accuracy. Unlike WHOIS-based tools, RDAP returns structured JSON data making results more reliable.

Results

You can check up to 50 TLDs in a single request. Our tool supports 1500+ TLDs including all popular extensions like .com, .net, .org, .io, .ai, .co, and hundreds more. For bulk checking of full domain names, use our bulk endpoint which supports up to 50 domains per request.

API Endpoint

Yes! DomScan provides a REST API for programmatic access. Use GET /v1/status for single checks or POST /v1/status/bulk for batch operations. The API returns JSON with availability status, RDAP source, and response latency. Perfect for domain registrars, brand monitoring tools, and investment platforms.

Example Request

Example Request http

GET /v1/status?name=example&tlds=com,io,ai

Example Response

Example Response json

{
  "results": [
    { "domain": "example.com", "available": false },
    { "domain": "example.io", "available": true }
  ]
}

Built from the same API surface

The browser experience previews DomScan's structured endpoints, so teams can validate a use case before writing code.

Frequently Asked Questions

How accurate is the domain availability check?

We use the RDAP protocol (Registration Data Access Protocol) which queries official registry databases directly. This provides real-time, authoritative availability data with 99%+ accuracy. Unlike WHOIS-based tools, RDAP returns structured JSON data making results more reliable.

How many TLDs can I check at once?

You can check up to 50 TLDs in a single request. Our tool supports 1500+ TLDs including all popular extensions like .com, .net, .org, .io, .ai, .co, and hundreds more. For bulk checking of full domain names, use our bulk endpoint which supports up to 50 domains per request.

Is there an API for automated domain checking?

Yes! DomScan provides a REST API for programmatic access. Use GET /v1/status for single checks or POST /v1/status/bulk for batch operations. The API returns JSON with availability status, RDAP source, and response latency. Perfect for domain registrars, brand monitoring tools, and investment platforms.

Why do some domains show as taken but appear available elsewhere?

Domain status can change rapidly. Our tool queries registries directly for real-time data, which may differ from cached results on other sites. A "taken" status means the domain is registered in the official registry. Some tools use DNS-based checks which can show false positives for parked domains.

What should I do after finding an available domain?

Once you find an available domain, we recommend: 1) Check the domain health and history using our WHOIS tool to ensure it has no negative reputation, 2) Use our valuation tool to understand fair market pricing, 3) Register quickly as good domains get taken fast, 4) Consider registering common typos using our typosquatting tool to protect your brand.
