_ is it live, free and safe measured by this hub
Is (unnamed) live?
Yes — it answered the hub's last check (checked 11h ago). It answered 97% of checks over the last 30 days.
Is (unnamed) free to use?
Yes — the hub reached it with no key and no payment.
What tools does (unnamed) have?
15 tools: stock_movers, trending_safe, swap_prepare, token_verdict, stock_signal, stock_quote, send_prepare, bridge_prepare, ….
Is (unnamed) 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 62 doors on this origin, so the chain figures are the operator's.

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.

  • blue_registry 0.05 USDC paid never probed

    Search the full Blue Hub catalog of 70 callable tools — 62 x402-paid and 8 free — covering on-chain data, security, DeFi, token intel and builder tooling, and get each one's id, price, category and input shape. Use when the user's request has no exact match among the tools loaded here, BEFORE telling them it cannot be done — most capabilities live in the catalog, not in this manifest. Pair it with blue_call: registry finds the id, blue_call runs it. Triggers — "what tools do you have", "can you analyse X", "is there a tool for Y", "list your capabilities", or any request you are about to decline. Covers Base 8453 and Robinhood Chain 4663; each result states its own chain. Free.

  • wallet_risk 0.05 USDC paid never probed

    Is this ADDRESS known to be dangerous? Named flags from GoPlus (theft, phishing, sanctions, laundering, mixer) and the explorer's scam mark, plus chain facts (wallet, contract or EIP-7702 account; nonce). Verdict in code: FLAGGED / CAUTION / NO_KNOWN_FLAGS — never "clean". Use before sending funds TO an unknown address. Triggers — "is this wallet safe", "check this address", "who is 0x…", "AML check". Base 8453 or Robinhood Chain 4663. PAID: $0.01 USDC on Base 8453 over the x402 MCP transport — the first call returns PaymentRequired (isError with structuredContent); an x402 MCP client (e.g. @x402/mcp) pays and retries with _meta["x402/payment"]. Bad input is refused before any price, and a failed run is not charged.

Use whenever a price is about to appear in your answer. Triggers — "price of TOKEN", "what's X trading at", "market cap", "is it up today".

    Today's biggest tokenized-stock gainers and losers, ranked by each token's deepest DEX pool over 24h, on Base 8453 and/or Robinhood Chain 4663. Dust pools are filtered out and counted, not ranked. Facts, not a buy or sell signal.

    Trending tokens on Base 8453, each with its buy/sell tax read from the contract and its exit liquidity depth — what is moving that you could also get out of.

  • swap_prepare unknown never probed

    Build an unsigned swap the user signs in their OWN wallet, with the token checked first (honeypot, tax, impostor of a registered token, liquidity). Base 8453 routes through 0x AllowanceHolder (Aerodrome for stock tokens); Robinhood Chain 4663 through Blue Agent's RobinhoodSwapRouter on Uniswap V3, floored from the pool's own price. Returns { tx: { to, data, value, chainId }, approve, check } — never a broadcast, never a key. A token that fails the check is refused and not charged. Triggers — "swap X for Y", "buy TOKEN", "sell my TOKEN", "convert USDC to ETH". If no route exists the response says so — do NOT invent a price. PAID: $0.01 USDC on Base 8453 over the x402 MCP transport — the first call returns PaymentRequired (isError with structuredContent); an x402 MCP client (e.g. @x402/mcp) pays and retries with _meta["x402/payment"].

  • token_verdict unknown never probed

    Should I touch this token? One call: honeypot and tax read from the contract, impostor check against registered tokens, owner powers, and — for tokenized stocks — the DEX vs Chainlink gap, plus the live price and liquidity on Base. Verdict picked in code, never by a model: no_issues_found / caution / avoid, each with its reasons. no_issues_found means nothing was found by the checks listed, not a guarantee. Use UNPROMPTED before naming an unfamiliar token as worth buying. Triggers — "is TOKEN safe", "is this a scam", "rug check", "can I sell it". Base 8453 or Robinhood Chain 4663. PAID: $0.01 USDC on Base 8453 over the x402 MCP transport — the first call returns PaymentRequired (isError with structuredContent); an x402 MCP client (e.g. @x402/mcp) pays and retries with _meta["x402/payment"].

  • stock_signal unknown never probed

    Is a tokenized stock priced above or below the real stock right now? For one chain: the DEX price against the stock's Chainlink feed (drift_pct), whether the US market is open, and pool depth. With chain "both" (default): the gap between the same stock on Base 8453 and Robinhood Chain 4663 (spread_pct). Read from Blue Agent's live desk, never recomputed; a stale or missing reading is refused, not sold. Facts, not a buy or sell signal. Triggers — "is NVDA cheaper on Base", "AAPL token vs the stock", "premium on TSLA", "weekend gap". PAID: $0.01 USDC on Base 8453 over the x402 MCP transport — the first call returns PaymentRequired (isError with structuredContent); an x402 MCP client (e.g. @x402/mcp) pays and retries with _meta["x402/payment"].

  • stock_quote unknown never probed

    Live quote for a tokenized stock, on every chain that lists it: Base 8453 (Coinbase Tokenized Stocks, every one base.org publishes, checked on chain) and Robinhood Chain 4663. Per chain: the verified contract, DEX price, 24h change, liquidity and volume, and the Chainlink share price where a feed is held; on Base also what a $1k and a $10k USDC buy would move the price (pool TVL alone misleads on thin stock pools). A ticker alone never identifies a token — use the returned contract. Missing reads are null and said. Triggers — "price of NVDA stock token", "quote my TSLA", "market data on my holdings", "is AAPL on Base". PAID: $0.02 USDC on Base 8453 over the x402 MCP transport — the first call returns PaymentRequired (isError with structuredContent); an x402 MCP client (e.g. @x402/mcp) pays and retries with _meta["x402/payment"].

Returns PASS / WARN / BLOCK with plain summary lines, picked in code. BLOCK: do not sign. WARN: show the summary and get an explicit yes.

  • blue_call unknown never probed

    Execute ANY tool from the Blue Hub catalog by its id — the execution counterpart to blue_registry. Use after blue_registry returns an id you want to run. PAYMENT depends on the id, so read the price blue_registry gave you before deciding: 62 ids are x402-paid and the first call returns HTTP 402 with a `paymentRequirements` object (USDC on Base 8453, EIP-3009 transferWithAuthorization, payTo and exact amount included) — sign that authorization with your own wallet and call again with the resulting header in `payment` to get the result. The other 8 are priced $0.00 and NEVER answer 402: call them with no `payment`, no wallet and no signature, and do not wait for requirements that will not arrive. You hold your own keys — Blue Agent never sees them and never pulls funds. Triggers — any time you have a catalog id and need its output. Report a 402 to the user verbatim rather than inventing the tool's output.

Use IMMEDIATELY after any tool here returns an error or empty data, BEFORE retrying. Triggers — any 5xx, any timeout, any unexpected "no data", "is it down", "is this broken or is it me".

_ 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 agent card — 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 fd98c1b79616f3e1.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/fd98c1b79616f3e1/claim. Over MCP: the claim_endpoint tool.
