api record

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…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 3 tools
3 never probed 0 of 3 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.

  • 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.

    prediction-marketssearchevents

  • 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.

_ try it over a2a 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

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.

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.
