Kalshi Polymarket Spread

graphadvocate.com · General

Cross-source arbitrage spread between Kalshi and Polymarket on a topic. POST {topic, limit?}. Pulls matching markets from both venues (Politics + Elections overlap heavily), computes price mid-spread + arbitrage direction. JOIN that single-source passthrough APIs (incl. Pinax Token API) structurally can't return — this is what survives Pinax shipping Kalshi support later.
