check_name
Check whether a brand, business, product, or app name is available. Runs a real-time availability check across: the US trademark registry (USPTO — live registry data, not guesses), domain names (.com, .io, .co, .app, .dev, with registration prices), social handles (X/Twitter, Instagram, TikTok, LinkedIn), developer namespaces (npm, PyPI, crates.io, GitHub, Docker Hub), and the iOS App Store. Returns a structured verdict (clear / caution / conflict), an overall viability band, and a link to the full interactive result. Use this whenever a user is brainstorming, choosing, or validating a name for a startup, company, product, app, or project and wants to know if it is taken, trademarked, or safe to use. Call once per candidate name. Free, no API key (shared daily fair-use pool). Data by nombrio.com.
Parameters1
| name | string | required | The candidate name to check, e.g. 'Lumeo'. Plain name only — no URL, no TLD, no @handle. One name per call. |
