Tools: check_resolution_risk list_covered_events
check_resolution_risk | Pre-trade safety check for cross-venue event markets (crypto
oracle-divergence pairs, metered; World Cup football, free). Flags
resolution mismatches, void-rule divergence, scope differences
(e.g. 90-minute vs extra-time; matched vs differing strike),
settlement-source and -timing gaps, stale data, and thin liquidity
between the two Polymarket and Kalshi legs BEFORE you execute both.
Returns a mac params: market_a, market_b, canonical_event_id, notional_usd, mode, api_key |
list_covered_events | Free discovery of everything check_resolution_risk can audit across
both inventories — the free World Cup football pairs and the metered
crypto oracle-divergence pairs (the 'crypto:' namespace is the paid
surface: $0.02 USDC per call after 3 free calls/day). Returns the
covered canonical events, their per-outcome pair ids (…#home / #draw /
#away for football), the Polymarket conditionIds and Kalsh params: none |
