Search events across all prediction-market venues
Keyless event search across Polymarket, Kalshi, Rothera, Limitless, Smarkets, Manifold, Metaculus, PredictIt, Futuur, Myriad, ForecastEx and Gemini. Results remain visible when quality-blocked; inspect quality and decisionSupport before using a row for a decision. This research endpoint is broader than the authenticated paper-trading discovery API.
Open events of a venue CoinRithm has paused (no longer collecting) are left out of this list, the overview, expiring and matches surfaces; their closed and resolved history stays available. pagination reports limit, offset and hasMore.
Opt-ins (absent means the default shape): view=compact keeps each event's top 3 outcomes by probability, adds outcomesTotal and drops description; lead=representative (with view=compact only) adds representativeOutcome on open events; dedupe=matched keeps only the highest-ranked member of each approved cross-venue match group on the page (a page can then hold fewer than limit rows); minVolume24h keeps events with at least that 24h USD volume; includeQuoteEvidence=1 adds quoteEvidence to every outcome.
An unknown query parameter returns 400 with a message naming the supported parameters.

Query parameters
Search title, outcomes (4+ character words), topics and related coins. The server normalizes the query (Unicode NFKC, whitespace collapsed, lower-cased) and TRUNCATES it to the first 80 code points and the first 6 words; longer input is not rejected. %, _ and \ are matched literally, never as wildcards. Words of 1-2 characters match on word boundaries only.
open (the default when absent or empty), closed, or any other value such as all for every status.
Restrict to plausibly mock-tradeable markets. Only the value true enables it.
compact returns each event's top 3 outcomes plus outcomesTotal, without description. Other values return the default shape.
representative adds representativeOutcome to open events. Applies only with view=compact.
matched keeps the highest-ranked member of each approved cross-venue match group on the page.
Minimum 24h volume in USD. Ignored unless a finite number above 0.
1 adds quoteEvidence to every outcome. Any other value returns 400.
