api record

Tools for AI agents: validate Latin American tax IDs (Brazil CNPJ, Argentina CUIT, Chile RUT, Peru RUC, Paraguay RUC with checksum; Mexico RFC format), check whether a public URL is up, and look up npm / PyPI / GitHub metadata. The same tools are available as pay-per-call REST endpoints (x402, USDC on Base) at https://agents.supremeai.ca.

Is supremeai live?
Not measured yet: the hub has not completed a check of this server.
Is supremeai free to use?
Not measured yet.
What tools does supremeai have?
7 tools: validate_tax_id, check_url_health, validate_tax_ids_batch, npm_package_info, github_repo_info, preflight_check, pypi_package_info.
Is supremeai safe to connect?

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 3 doors on this origin, so the chain figures are the operator's. How it is counted.

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.

_ try it over mcp 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 fb51260d06560c39.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/fb51260d06560c39/claim. Over MCP: the claim_endpoint tool.

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 knowoff the mcp door
card completeness
100%

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.
