How this service works
Live sports-market mispricing detector. POST {milestone, market?}. Combines Kalshi's public play-by-play game_stats (Football/Basketball/Soccer/Hockey/Baseball/WNBA) with market candlesticks over the last hour to flag latency-arb windows when in-game momentum and market price diverge. Returns momentum_score, market_reaction_pct, and a directional latency-arb signal.
Output
Returns a JSON object with a milestone ID, number of candles returned, a latency arbitrage signal label (e.g. 'upside-lag-likely'), a momentum score over the last 5 events (0–1), and a market reaction percentage over the last hour. Useful for identifying live edge opportunities in Kalshi sports prediction markets.
Example use cases
Example prompt
“Can you check Graph Advocate's Kalshi sports live edge endpoint for any latency arbitrage signals on the NFL game milestone NFLGAME-XYZ-1 right now — I want the momentum score over the last 5 events and the market reaction percentage from the last hour?”

Endpoint
POSThttps://graphadvocate.com/kalshi/sports-live-edgeWhen to prefer
Use this endpoint when you need real-time sports prediction market signals from Kalshi, specifically latency arbitrage detection and momentum scoring tied to live event milestones. Prefer this over generic sports data APIs when you need onchain-indexed market reaction data and are willing to pay per-call via USDC on Base.
Side effects
- Free tier exhausted (3 queries/day limit reached) — payment of $0.05 USDC on Base required via x402
- Invalid or unrecognized milestone ID — may return empty or null data
- No live sports event active — candles_returned may be 0
- x402 payment failure — endpoint returns 402 Payment Required
- Ambiguous plain-English query — routing agent may select wrong subgraph or return generic GraphQL
