api record

quarry is a marketplace of sourced documents (reports, filings, research, data) that agents can search and cite. Use search first (free), then ask one dataset for full passages with citations. Free datasets answer directly; paid ones use the user's subscription or an x402 payment from your own wallet. Tell the user the price before paying, and never subscribe for them: request_subscription only prepares a Checkout link they confirm. Cite each passage's filename, page or rows (when present) and listing URL, as ask's how_to_cite shows. Using quarry means accepting its terms:…

_ is it live, free and safe measured by this hub
Is quarry live?
Yes — it answered the hub's last check (checked 3h ago). It answered 100% of checks over the last 30 days.
Is quarry free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does quarry have?
7 tools: search, get_dataset, get_my_access, request_subscription, x402_payment_guide, quote_access, ask.
Is quarry 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.

_ what it can do 7 tools
6 auth-required 1 never probed 6 of 7 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.

  • get_dataset reads auth-required never probed

    One dataset's description, price per question, monthly subscription, response format and how to pay. Free. When your quarry account is connected, also shows your access and the questions left this month.

  • ask reads auth-required never probed

    Get the passages of one dataset that answer a question, each with its source file, page or rows, section and date for citation. Free datasets answer directly. Paid ones use your subscription when your quarry account or API key is connected; otherwise pay with x402 by retrying with a PaymentPayload in _meta["x402/payment"]. Without either, returns the price and how to pay. Returned passages count as a paid question even if they answer only part of it; when the relevance check finds none that answers it, returns NO_MATCH and nothing is charged. Pass a request_id and reuse it only to retry the same question.

  • search reads unknown 3h ago

    Search every dataset on quarry for sources that answer a question: reports, filings, research and data published by the people who produced them. Free, no account needed. Returns the most relevant datasets with their price and how to ask; the top five also carry a short preview (up to 200 characters) of their best-matching passage when the seller allows it. Then call ask for the full, cited passages.

_ 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 a412e986b0527f5b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/a412e986b0527f5b/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/a412e986b0527f5b/badge.svg)](https://brick.blue/agent/a412e986b0527f5b?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
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.
