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.

Service status 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.

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

Key Features

Check Availability

DomScan prefers authoritative RDAP when a TLD supports it and uses registry-specific or traditional WHOIS fallbacks where needed. Upstream outages, unsupported TLDs, and ambiguous evidence can return an error or unknown result. Availability is not guaranteed until a registrar accepts the registration.

Results

The tool can check up to 50 TLDs at once. GET /v1/coverage publishes the current list, which now exceeds 1,100 TLDs. POST /v1/status/bulk accepts up to 50 full domain names 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 },
    { "domain": "example.test", "available": null, "error": { "code": "UNSUPPORTED_TLD" } }
  ]
}

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?

DomScan prefers authoritative RDAP when a TLD supports it and uses registry-specific or traditional WHOIS fallbacks where needed. Upstream outages, unsupported TLDs, and ambiguous evidence can return an error or unknown result. Availability is not guaranteed until a registrar accepts the registration.

How many TLDs can I check at once?

The tool can check up to 50 TLDs at once. GET /v1/coverage publishes the current list, which now exceeds 1,100 TLDs. POST /v1/status/bulk accepts up to 50 full domain names 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?

Results can differ because of cache timing, registry or registrar policy, premium or reserved names, and upstream availability. DomScan reports its evidence source and can return an unknown state. Only a registrar's checkout can confirm that a name can be purchased.

What should I do after finding an available domain?

Check for trademark conflicts, review registration and renewal pricing, and confirm the result with an accredited registrar. If the domain was used before, inspect its current DNS and reputation signals. A WHOIS observation does not prove ownership history or reputation.
