_ is it live, free and safe measured by this hub
Is SignalLayer live?
Yes — it answered the hub's last check (checked 46m ago). It answered 100% of checks over the last 30 days.
Is SignalLayer free to use?
Yes — the hub reached it with no key and no payment.
What tools does SignalLayer have?
5 tools: signal_layer_router, market_execution_intel, signal_layer_catalog, agent_preflight, structured_extract.
Is SignalLayer safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

counted from three payers (thin, concentrated)

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 5 tools
5 never probed 0 of 5 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.

  • signal_layer_router unknown never probed

    Free deterministic SignalLayer task router. USE THIS when the task is known but the correct SignalLayer primitive is not. Returns either no_match or one recommended tool with price, missing inputs, and ready-to-call HTTP and MCP arguments. It never forces a paid recommendation.

  • market_execution_intel unknown 46m ago

    Before an exact-in ERC-20 swap on Base when current quote-derived execution conditions, network cost, and size sensitivity matter. Do NOT use when: You need generic historical prices, personalized investment advice, or a signed transaction. Price: $0.03 USDC via x402. If uncertain which SignalLayer primitive matches the task, call signal_layer_router first for free.

  • signal_layer_catalog unknown never probed

    Free machine-readable SignalLayer capability catalog. Use this to enumerate all SignalLayer tools and prices. If the correct tool is uncertain, prefer signal_layer_router.

  • agent_preflight unknown 46m ago

    Before paying, transferring to, or interacting with an unfamiliar machine resource, x402 endpoint, recipient, or Base address. Do NOT use when: You only need market execution conditions or webpage extraction. Price: $0.01 USDC via x402. If uncertain which SignalLayer primitive matches the task, call signal_layer_router first for free.

  • structured_extract unknown 46m ago

    When requested facts exist on a public webpage but compact structured JSON is needed instead of browsing and parsing the page. Do NOT use when: The source is already structured or the task is generic web search. Price: $0.02 USDC via x402. If uncertain which SignalLayer primitive matches the task, call signal_layer_router first for free.

_ 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 e30c866e2c60dc4b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/e30c866e2c60dc4b/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/e30c866e2c60dc4b/badge.svg)](https://brick.blue/agent/e30c866e2c60dc4b?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
90%

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.
