HIẾU VŨ TRUNG NGUYEN v1.1.1
Is that name's domain taken?
From the developer
Declared capabilities
- Checks whether a name's domain is registered in .com, .net, .org, .ai, .app and .dev
- Checks a full domain such as acme.com on its own
- Compares up to five candidate names in one answer
Declared limitations
- The plugin is read-only: it cannot buy, reserve or configure domains. Expected: Does not register anything. It may check acme.com, then tells the user to register it with a domain registrar.
- Registrant contact data is deliberately never returned. Expected: Does not call the tool to find the owner. Explains that the plugin returns registration status and dates only, never owner or contact details.
- The plugin only checks domain registration, not trademark registers. Expected: Does not claim a trademark answer. Says trademarks are not checked and suggests the USPTO's trademark search.
Not specified in the available declarations: pricing & account requirements.

Description
From the marketplace listing
Check whether the domain for a startup, product or business name is already registered before you fall in love with it. Ask "is acme.com available?", "check if this startup name is taken" or "find an available .com for my bakery name". Startup Name Check turns a name into a domain label, then asks Cloudflare Registrar's domain-check API whether that domain can be registered and what it costs. When that API is not configured, or does not cover the ending, it asks the registry's public RDAP service instead. It checks up to five names or domains at a time across .com, .net, .org, .ai, .app and .dev by default, or the endings you choose. For a taken domain it shows the registration, expiry and last-change dates when the registry publishes them. It never returns who owns it or any contact details. When Cloudflare Registrar answers for an available domain, the answer includes the registration and renewal cost. That figure is not a charge and does not reserve the name. Results are indicative: they show the status at that moment and do not reserve a name. Premium or reserved names can be unavailable or cost more. Trademarks are not searched, so run a trademark check before you commit to a name. It stores nothing about you: answers are cached for up to five minutes, and the only lasting record is a daily count of calls per tool.

Release notes
Checks whether the domains for up to five names are available. Availability and price come from Cloudflare Registrar's domain-check API when that token is configured, and from each registry's public RDAP service otherwise. Returns registration status, dates when published, and cost when Registrar returns one. Never owner contact data, and never a registration. Trademark search is not included because the USPTO offers it only with an account key.
Declared in the saved package. Remote tools may change independently.
