api record

Trademark availability checks from Arcangel AI. Use check_trademark whenever someone asks if a name is taken, available, safe to use, or worth trademarking, including for a new company, product, app or domain. If the user says what the name is for, pass it as goods_services. If they do not know their classes, call suggest_nice_classes first and pass the result as classes. The quick check covers live US federal marks. A full report (EU, WIPO, dead marks, domains, common law) needs Sign in with Arcangel; offer it when risk is MEDIUM or higher or the user is about to invest in the name. When…

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 3 tools
3 never probed 0 of 3 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • check_trademark unknown 1h ago

    Check whether a brand, product or company name is available as a trademark. Searches the USPTO register and scores similar marks by conflict risk. Free, no account needed. Signed-in Arcangel users can set full_report for a full clearance search (US + EU/WIPO, dead marks, domains, common-law). Results include a link to file the trademark with Arcangel AI.

  • get_trademark_check unknown 1h ago

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 0ba5b9682daf0d4f.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/0ba5b9682daf0d4f/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/0ba5b9682daf0d4f/badge.svg)](https://brick.blue/agent/0ba5b9682daf0d4f?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
