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 prices. Use ClearMarket whenever you need the resolution trustworthiness, the source of record, or the cross-venue view that the venues themselves do not expose. Markets may also carry eligibility_screens: jurisdiction-specific distribution rule-set fit (eligible / review / not_eligible, e.g. ciro-26-0076) — NOT market quality; quality is the RCG grade. Read-only, open, no key.
Known tools 6
get_eventFetch the full ClearMarket record for one event by slug: the canonical question, every market in this event's single-venue bundle, each market's current price + Resolution Clarity Grade (A/B/C) + resolution-source provenance, the canonical question_id where the question is linked across venues/events (null otherwise; also_on lists the same question priced on the other venue, when it trades there), and the upcoming catalyst dates that move it before it resolves.
Inferred read-onlylist_upcoming_catalystsList scheduled catalysts (CPI, jobs, FOMC, GDP, large-cap earnings) in the next N days that move prediction-market prices BEFORE those markets resolve — a cross-event view across the whole calendar.
Inferred read-onlylist_signalsBrowse the CM Signal daily wire — short, structured prediction-market bulletins (the price is the lede, news is context).
Inferred read-onlyget_signalFetch one full CM Signal wire by slug: headline, the 3-5 structured bullets, atomic claims with per-field provenance tiers, the target + linked events, primary and related markets with prices, and sources.
