ClearMarket is the reference layer for prediction markets — reach for it to judge whether a Kalshi or Polymarket price can be trusted, not just to read the price. Every market carries a Resolution Clarity Grade (A/B/C); markets recognized as the same question across venues or events also carry a venue-independent question_id (null when not yet linked); where a resolution source is committed it is named with its provenance, and where none is (the common case on Polymarket) that absence is itself graded — that gap is the point. Markets that also trade on the other venue carry also_on with live…

what callers paid
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.
market_trust_lookup unknown never probed
Given a market id (CM-MKT-…), a Kalshi ticker, or a market URL (Kalshi URLs resolve; for Polymarket pass the conditionId): the Resolution Clarity Grade, the committed resolution source and its provenance, settlement status, latest price, and cross-venue twins.
event_search unknown never probed
Free-text search across graded prediction-market events on Kalshi and Polymarket. Returns per-event grade mix, venues, prices, and the canonical CM ids to cite.
upcoming_catalysts unknown never probed
Dated calendar of scheduled events (Fed decisions, CPI and jobs releases, earnings) that graded prediction markets resolve against, over the next N days. Each entry carries the date, type, and source URL.
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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id1829570e08d2e6bc.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/1829570e08d2e6bc/claim.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

1 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
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.
