How this service works
Use this to rank covered markets where Quotient's probability differs from a verified live venue quote. The endpoint batches live reads, then applies the odds band, spread threshold, direction, and sort to one selected quote. Missing, stale, and unsupported live quotes are excluded. Returns quote provenance, routing, Q probability, spread, thesis, and venue-reported volume.
Output
A ranked list of prediction markets where Quotient's modeled probability diverges from live venue odds, including: each market's Quotient forecast probability, current venue odds, spread in percentage points, direction of mispricing (market over- or under-priced), Quotient's thesis for its forecast, market volume, and venue. Results are ordered by the requested sort field (default: spread descending).
Example use cases
Election market edge scan
“Find me the biggest mispricings on Kalshi for election and politics markets right now — sort by spread descending and filter to markets where the gap is at least 8 percentage points.”
Daily value bet sourcing
“Pull Quotient's mispriced market screen across all venues sorted by volume so I can see which high-liquidity markets have the most edge today.”
Geopolitics trading idea generation
“I'm looking for value bets on geopolitics and macro prediction markets — show me where Quotient's forecast disagrees most with live odds on Polymarket, ranked by edge, with spreads of at least 5%.”
Technical details
Endpoint
GEThttps://quotient-api-gateway.onrender.com/api/v1/markets/mispricedWhen to prefer
Use this endpoint when you need to actively screen for trading opportunities rather than browsing all markets — it is the purpose-built mispricing scanner that saves you from computing spreads yourself. Prefer this over the general market browse endpoint when your goal is edge discovery. Choose it when you want to filter by venue, sort by spread magnitude, or set a minimum disagreement threshold to focus only on high-conviction discrepancies.
Side effects
- No markets found matching filter criteria — try reducing min_spread or removing venue filter
- Stale forecasts if max_forecast_age is set very low and Quotient hasn't updated recently
- Venue temporarily unavailable — some markets may be excluded from results
- Payment failure or insufficient USDC balance returns 402 error
- Rate limiting or service unavailability on Render hosting returns 5xx
