Live brand-name checks in your AI assistant: US trademark verdict, EU screen, domains, social handles. Free.

Nombrio gives your AI assistant live brand-name checks — US trademark verdict (USPTO), EU screen (EUIPO), domain prices, social handles, developer namespaces (npm, PyPI, crates.io, GitHub, Docker Hub) and the iOS App Store — free, no account.

Tools: check_name (one name), check_names (2–8 names in one call, ranked), prompt naming-session (brainstorm → screen → shortlist).

With a Nombrio API key (Authorization: Bearer , created at https://nombrio.com/dashboard/api-keys): the same tools run the full US+EU+UK Clearance Check with named conflicting marks and an exact 0–100 score, and start_naming_session / get_naming_session start a Naming Session — eight pre-cleared names from a one-line brief — metered against your plan.

Setup for Claude Code, Cursor, VS Code, Claude.ai, ChatGPT and more: https://nombrio.com/mcp · REST: https://nombrio.com/api/v1/check?name=

Trademark screening, not legal advice. Operated by sydacos GmbH (Germany), data processed in the EU.

check_nameRun a free Clearance Check on ONE brand, business, product or app name. Live registry data, not guesses: US trademark verdict (USPTO — clear / caution / conflict with a count of live registrations), a count-only EU trademark screen (EUIPO), domain availability with prices (.com .io .co .app .dev), social handles (X/Twitter, TikTok, LinkedIn, Facebook; Instagram returns a confirm-link), developer namespaces (npm, PyPI, crates.io, GitHub, Docker Hub), the iOS App Store, and an overall viability band (strong / caution / blockers / high-risk) plus a link to the full interactive result. Use it when the user asks whether a SPECIFIC name is taken, trademarked, available or safe to use. For a shortlist or comparison use check_names instead — one call, all names in parallel, ranked. Free, no API key; shared fair-use pool with a per-caller daily allowance. Not legal advice. Data by nombrio.com.
check_namesScreen 2-8 candidate names in ONE call and get them ranked by viability (best first). Runs the same live free Clearance Check as check_name for every name in parallel — US trademark verdict, count-only EU trademark screen, domains with prices, social handles, developer namespaces, iOS App Store — and returns a ranked summary, per-name verdicts and full-result links. Use it whenever the user is brainstorming, has a list, or asks which of several names is available or safest: one check_names call replaces many check_name calls and finishes in about the time of one. Each name counts as one check against the free fair-use pool (per-caller daily allowance). Not legal advice. Data by nombrio.com.
start_naming_sessionRequires a connected plan (API key). Starts a Nombrio Naming Session: from a one-paragraph brief, generates up to 8 name ideas and pre-clears each with the same Clearance Check registries as check_name (US+EU+UK trademark, domains, social handles). Asynchronous — returns a sessionId; poll get_naming_session every ~10 s; typically 1–3 minutes. Uses one Naming Session from the plan (Clearance Report 10/30 days, Pro 30/month, Premium unlimited). Without a key it returns instructions to connect a plan.
get_naming_sessionRequires a connected plan (API key). Polls the status of a Naming Session started with start_naming_session: pending/generating/checking/complete/failed, plus the ranked name list (score, trademark/domain/social status) once complete — pair with check_name's Clearance Check for a deeper read on the favourite. Without a key it returns instructions to connect a plan.
