Brand Name Availability Checker — Domains + USPTO Trademarks

Check whether a business or product name is actually free to use in one step: domain availability (.com, .net, .org, .ai, .io, .co and 1,000+ other extensions) plus live US trademark conflicts from the USPTO. Paste up to 2,000 names and get a clear verdict for each.

Why use it

• Two checks, one run. Most tools only check domains. A free .com means nothing if someone already owns the trademark.
• Bulk naming. Brainstorm 50 names with ChatGPT, paste them in, keep the ones marked GREAT.
• Official sources. Domains come from the registries' own RDAP service (the modern WHOIS); trademarks come from the USPTO's trademark search database.
• Registrar and expiry dates for taken domains, so you can spot names that might drop soon.

Who it's for

Founders and startups, Etsy / Shopify / Amazon sellers, naming and branding agencies, app developers, domain investors, and anyone launching a product.

Verdicts

Verdict	Meaning
GREAT	The .com is available and no conflicting live trademarks were found
GOOD	The .com is taken, but other extensions are free and no strong trademark conflict was found
RISKY	A live trademark contains this name or the name contains a multi-word mark — review before using
AVOID	A live trademark matches this name
TAKEN	Every checked domain is registered

Example input

{
  "names": ["Tasty Brew Co", "Zorbly Labs", "Mama Bear"],
  "tlds": ["com", "io", "ai"],
  "trademarkClasses": ["30", "43"],
  "suggestVariations": true
}

Output (one row per name)

{
  "name": "Zorbly Labs",
  "domainLabel": "zorblylabs",
  "verdict": "GREAT",
  "summary": "The .com is available and no conflicting live trademarks were found.",
  "comStatus": "AVAILABLE",
  "availableDomains": ["zorblylabs.com", "zorblylabs.io", "zorblylabs.ai"],
  "takenDomains": [],
  "domains": [
    { "domain": "zorblylabs.com", "status": "AVAILABLE", "method": "rdap" },
    { "domain": "zorblylabs.io", "status": "LIKELY_AVAILABLE", "method": "dns" }
  ],
  "trademarkRisk": "NONE_FOUND",
  "trademarkSummary": "No live matching trademarks found in the selected classes.",
  "trademarkConflicts": [],
  "trademarkClassesChecked": "ALL"
}

Taken domains include registrar, created and expires dates where the registry provides them.

Domain status values

• AVAILABLE — the official registry (RDAP) says the domain isn't registered.
• REGISTERED — the domain is taken.
• LIKELY_AVAILABLE — for extensions without a public RDAP service (e.g. .io, .co), the domain has no DNS records. Almost always available; confirm at checkout.
• UNKNOWN — the registry didn't answer; try again later.

Pricing

$5 per 1,000 names checked ($0.005 per name) — every extension you choose and the trademark check are included. Set a maximum cost per run and the Actor stops cleanly when it's reached.

Notes

• Trademark check covers US federal (USPTO) marks only and uses text matching; it doesn't judge logos or "likelihood of confusion."
• Premium or reserved domains may show as available in RDAP but cost more at registrars.
• Not legal advice. For an important brand, have a trademark attorney run a full clearance search.
