How this service works
Paid ($0.02 USDC via x402). Markets resolving within ?withinHours (1-72): odds, contested-vs-converged, liquidity, and order-book microstructure for the nearest expiries. Mechanical short-interval markets excluded by default (?includeNoise=1 to include). Settle-early with a guaranteed refund — if we charge you but cannot deliver, the payment is refunded.
Output
A list of Polymarket markets resolving within the requested horizon, each with current odds, contested-vs-converged status, liquidity depth in USD, and order-book microstructure data for the nearest expiries. Short-interval mechanical markets are excluded by default unless the noise flag is set.
Example use cases
Scout near-expiry trading opportunities
“Find me all Polymarket markets resolving in the next 6 hours that still look contested — I want the current odds and order-book depth so I can decide if any are worth trading into before they settle.”
Identify deep-liquidity converging markets
“Show me prediction markets expiring within the next 48 hours that have converged heavily to one side but still have deep liquidity — I'm looking for markets where the outcome looks almost certain so I can assess the risk-reward before resolution.”
Monitor today's settlement calendar
“Give me a full rundown of every Polymarket market settling today, with live odds and whether they're still contested or basically resolved — skip the noisy short-interval ones and just focus on the real events.”
Technical details
Endpoint
GEThttps://api.orcatrace.dev/v1/resolvingWhen to prefer
Use this endpoint when you need a focused view of only near-expiry Polymarket markets — it filters by resolution horizon and liquidity floor automatically, and surfaces order-book microstructure (contested vs converged) that raw Polymarket feeds don't surface. Prefer this over the general feed or digest endpoints when timing-sensitive trading decisions require knowing which markets are about to settle.
Side effects
- withinHours out of range (must be 1–72) → 400 validation error
- minLiquidity below 1000 → 400 validation error
- No markets found matching criteria → empty result set
- Payment not settled via x402 → 402 Payment Required with refund guarantee
- Upstream Polymarket data unavailable → service error with automatic refund of $0.02 USDC
