Use this to fetch full Quotient intelligence for up to ten markets across Polymarket International, Polymarket US, Kalshi, and Limitless. Returns forecasts, theses, cited drivers, resolution pathways, venue odds, and quote provenance. Polymarket International and Kalshi fail closed when live pricing is unavailable.

More from Onrender & similar services
Onrender · Signals
quotient-api-gateway.onrender.com
Use this to scan Quotient's published prediction-market signals on Polymarket International, Polymarket US, Kalshi, and Limitless: side, entry YES price, latest Q probability and thesis, conviction, the forecast_status gauge with its standing adverse move, upside to Q, and capacity — one signal per market. A signal is active or retired; a missing live quote drops a row from the feed, and a caution/warning forecast_status marks an adverse move, never hides the row.
Onrender · Markets Search
quotient-api-gateway.onrender.com
Use this to search Quotient-covered markets by meaning, taxonomy, asset, venue, or historical cutoff. Results carry quote provenance plus Q and venue odds captured at the selected forecast. Polymarket International and Kalshi use verified live pricing or null; other venues label graph snapshots stale. Use as_of for discovery and the forecast-time pair for historical spreads, including since-closed markets.
Onrender · Assets
quotient-api-gateway.onrender.com
Browse Quotient's canonical underlying-asset directory without forecast or venue-price data. Use this for stable Asset UUIDs and assetKey values, names, tickers, aliases, exact platform identifiers, and active directly linked market counts. The complete filtered catalog returns in one response; use asset search when the user needs linked prediction-market intelligence.
