api record

AIMarket hub: live, signed real-world data and verifiable computation, sold per call by independent providers. For a common need call a direct tool when this server lists one (weather_now, air_quality_now, nearby_sensors, fair_random). For anything else: market_search with the user's need in plain words, pick a match, then market_invoke with that match's product_id, capability_id and source_hub, and an `input` object built from the match's `input` field. The first few priced calls per caller are a free trial and every result carries a signed receipt; when the trial is spent the tool returns…

_ is it live, free and safe measured by this hub
Is aimarket-hub-mcp live?
Yes — it answered the hub's last check (checked 45m ago). It answered 99% of checks over the last 30 days.
Is aimarket-hub-mcp free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does aimarket-hub-mcp have?
13 tools: market_invoke, pipeline_invoke, pipeline_refund_prepare, pipeline_refund, x402_check, pipeline_prepare, market_search, weather_now, ….
Is aimarket-hub-mcp 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 8 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.

  • weather_now reads 0.001 USDC paid never probed

    Current weather at a place: temperature (°C), humidity (%), pressure (hPa) and wind (m/s) from the nearest live Open-Meteo relay within 75 km, with a signed receipt. Pass latitude and longitude, or a city. Paid per call; market_search shows the current price. The first few priced calls per caller are free.

  • market_search reads open 7h ago

    Search this hub's catalogue of live data and computation by what you need, in plain words. Each match gives the product_id, capability_id and source_hub to pass to market_invoke, its price, `input` (the fields its input object takes) and `relevance` from 0 to 1; a `note` says when nothing matched well.

  • market_invoke moves money unknown never probed

    Invoke a capability found via market_search. A few trial invokes are granted per caller with no wallet, key or channel, and each returns the hub's signed receipt; when the allowance is spent the hub answers 402 and this reports that rather than inventing a result, with next_steps saying how to pay. Paid access uses the prepaid balance of an API key sent as this connection's X-API-Key header, payment_channel (+ secret), or an on-chain x402 payment (x_payment + x_payment_nonce + x_payment_secret).

  • pipeline_invoke moves money unknown never probed

    Execute or continue the SAME prepared graph. Submit authorizations when the signed quote enables gas_sponsorship, otherwise buyer-signed transactions; none for free steps. Never submit both payment modes. Retain run_id/access_token and the exact bundle. Pending is not failure; repeat the same run or read pipeline_status. Never create a replacement purchase after a lost response.

_ 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 84d8f4c5c1be792e.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/84d8f4c5c1be792e/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.

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.
