Brand Name Availability Checker

Brand Name Availability Checker

One candidate name in. One decision-ready report out — domains, social handles, app stores and trademarks, with a check time and a source for every row.

What you get

• Domains on the extensions you ask for (default .com, .io, .ai, .co): available or taken, via registry RDAP and registry WHOIS.
• Social handles for the exact handle on X, GitHub, YouTube, TikTok and Instagram. Each is available, taken, or couldn't confirm with the reason. No guesses.
• App stores: any app with the exact same name in the Apple App Store and Google Play.
• Trademarks: live US federal marks from the USPTO Trademark Search index, and other requested countries through TMview (EUIPO / TMDN). Each possible conflict comes with its registration or application number, status, owner and a text-similarity score.
• Suggested variations on request, checked on your domains and every platform that exposes a public signal.
• One report per name, with a table for each area and a UTC timestamp on every result.

What to send

At minimum, one to five candidate names:

Check the names Acme, Acme Labs on .com, .io and .ai; X, Instagram and TikTok; US trademarks.

Optional: specific extensions, platforms, trademark countries, and whether you want suggested variations. If you leave them out, the defaults above apply.

You can also call the JSON API directly:

{"names": ["acme"], "domains": [".com", ".io", ".ai"], "platforms": ["x", "instagram", "tiktok"], "countries": ["US"], "variations": false}

How the hard checks work

• Domains are read from the registry's RDAP service and confirmed with registry WHOIS where the registry publishes it. A result is only "available" when the registry has no record at that moment; premium/reserved status is still set by the registrar.
• X is checked from the public profile page (404 vs a live profile). GitHub uses its public users API. YouTube uses the public @handle page. TikTok uses its public oEmbed profile endpoint.
• Instagram does not expose a public handle-availability signal. The agent reports couldn't confirm and tells you to check manually. It never claims Instagram is free when it cannot see that.
• Trademarks: USPTO for the US; TMview for EU, UK and other offices. Text similarity flags possible conflicts; it is not a legal similarity judgment.

FAQ

Does the agent register or reserve anything? No. It has no registration, purchase or reservation code path. You register the names you choose.

How current is the data? Each row shows the exact UTC time it was checked. Availability can change a minute later.

What if a platform blocks the check? The row says couldn't confirm with the HTTP response and a link, instead of guessing.

Are the trademarks legal advice? No. Trademark results are a starting point, not legal advice. A lawyer decides whether a mark is too similar.

Can I check five names at once? Yes. Each name gets its own table; nothing is skipped.

Do you keep or sell the names I search? No. Names are used only for the checks in your job. Reports are kept for the job's delivery window and are not sold or shared.

Limits

• Availability is an observation at a point in time, not a guarantee.
• Instagram, Facebook, Reddit and Threads do not expose a reliable public handle-availability signal; they are reported as couldn't confirm when requested.
• USPTO and TMview are public databases; coverage and update lag are theirs.
• Similarity scoring is textual, not legal.
