Brand & Domain Name Availability Checker

Check a list of brand, startup, product or app names in one run. For every name you get:

• Domain status across .com, .com.au, .io, .ai, .co, .net (or any extensions you choose), from official RDAP registry data plus a DNS check
• Apple App Store clashes: apps with the same or a similar name, with developer and link
• US trademarks: how many live USPTO trademarks use the exact wording or contain the name, with the top marks, owners and classes
• A simple risk rating (LOW / MEDIUM / HIGH) with plain-English reasons
• One-click links to check Australian trade marks (IP Australia) and Google Play yourself

Use it to shortlist names before you buy a domain, brief a designer, or pay a trade mark attorney. Typical users: founders naming a startup, agencies pitching name options, app developers, Shopify and e-commerce brands, domain investors, and AI naming tools that need a fast "is this name taken?" check.

Why this checker

• Bulk: paste 5 or 5,000 names. One clean row per name, ready for Google Sheets or your app.
• Honest results: a domain with no registry record is reported as NO_RECORD_FOUND ("likely unregistered"), never as guaranteed available. Premium, reserved or just-dropped names can still be unavailable, so confirm at a registrar before you rely on it.
• Free public sources only, used within their terms. No scraping of sites that forbid it.
• Australia-friendly: .com.au by default, App Store storefronts for any country, and an IP Australia search link for every name.

How to use it

1. Enter your names under Brand names (one per line).
2. Optional: change the domain extensions, App Store countries (us, au, gb...), or turn checks off.
3. Click Start. Results appear in the Overview table; the Domains view shows registrar, registration and expiry dates where the registry publishes them.

Spaces and punctuation are removed for the domain part, so "Blue Fox Roasters" checks bluefoxroasters.com.

Input example

{
  "names": ["Zentrailo", "Koalafy", "Blue Fox Roasters"],
  "tlds": [".com", ".com.au", ".io", ".ai", ".co", ".net"],

  "checkUsTrademarks": true
}

A registered domain also carries registrar, registeredOn, expiresOn and the registry status codes when the registry publishes them in RDAP.

Domain status values

Status	Meaning
REGISTERED	The registry has an RDAP record, or the domain has nameservers in DNS. It is taken.
NO_RECORD_FOUND	No RDAP record and no DNS delegation. Likely unregistered, not guaranteed.
UNKNOWN	A source timed out or rate-limited us and DNS could not settle it. Re-run later.

Some extensions (for example .io and .co) have no public RDAP service, so they are checked by DNS only; the evidence field says so.

Risk rating

Points are added for: live US trademarks with the exact wording (3), live US trademarks containing the name (1), .com registered (1), half or more of the checked domains registered (1), an App Store app with the exact name (2) or a similar name (1). 0-1 = LOW, 2-3 = MEDIUM, 4+ = HIGH. It is a quick screening signal, not a clearance opinion.

Pricing

Pay per event: US$3.00 per 1,000 names checked (US$0.003 per name), whatever number of domains, countries and checks you choose. No subscription. You can cap spend with the run's maximum charge setting; the Actor stops cleanly when it is reached.

Speed

About 2-4 seconds per name with default settings. Apple asks API users to stay around 20 calls a minute, so each extra App Store country adds roughly 3 seconds per name. Turn the App Store check off for the fastest domain + trade mark screening. The default run timeout is 2 hours (about 2,000 names with one App Store country); for bigger lists raise the timeout in Run options or split the list.

Integrations: send results anywhere

• Google Sheets. Add the Google Sheets integration on the Integrations tab to append every checked name, with its risk and free domains, to a shortlist sheet.
• Zapier and Make. Use the Apify app with the trigger "Actor run finished", then "Get dataset items" to push results into Airtable, Notion, Slack or a CRM. A form submission (for example a "check my brand name" form on your site) can start a run.
• API. Call the Actor from any language with the Apify API or the apify-client package and read the dataset as JSON or CSV.
• AI agents and LLM tools. Give a naming assistant a real availability check: generate 50 candidate names with your LLM, run them here, and keep only the LOW-risk names with a free .com. Works with LangChain (ApifyWrapper / ApifyDatasetLoader), LlamaIndex, Flowise, and the Apify MCP server for Claude and other agents.
• Webhooks. Add a webhook for ACTOR.RUN.SUCCEEDED to call your own endpoint when results are ready.

Data sources and limits

Check	Source	Notes
Domains	RDAP via the IANA bootstrap registry, plus DNS NS lookups (Cloudflare and Google public DNS-over-HTTPS)	.io, .co and some others have no public RDAP, so DNS only
App Store	Apple iTunes Search API	Top 10 results per country, matched by name
US trademarks	USPTO Trademark Search (tmsearch.uspto.gov), public US government records	Live marks only; one small query per name, throttled. Wordmark text only, no design or sound-alike search
AU trademarks	Not queried automatically	IP Australia's search API requires an approved application; a free search link is included
Google Play	Not queried	No free public search API and Google's terms bar automated access; a search link is included

Trade mark search here is a first screen. It does not catch similar-sounding or misspelt marks, state or common-law rights, business names, or marks in other countries.

FAQ

Does "NO_RECORD_FOUND" mean I can register the domain? Usually, but not always. Registries reserve and premium-price some names, and a name can be registered between our check and your purchase. Check at a registrar.

Is this legal advice? No. This tool is a screening aid and not legal advice. Speak to a registered trade mark attorney before you commit to a brand.

Why no EU, UK or WIPO trademarks? The free EU and WIPO search tools do not allow automated searching in their terms, and we only use sources that permit it.
