How this service works
Kalshi consensus-probability trajectory. POST {event}. Wraps Kalshi's unique /events/{ticker}/forecast_history (no other PM exposes formatted forecast percentile history). Returns slope-per-hour over 24h and 3d, acceleration signal (regime change indicator), volatility band, days to resolve, and a stable/accelerating-up/accelerating-down interpretation.
Output
Returns a JSON object with the event title, a human-readable interpretation string (e.g. 'accelerating-down'), current consensus probability, slope per hour over 3-day and 24-hour windows, an acceleration signal, days to resolve, 24h volatility as standard deviation, and the Kalshi event ticker.
Example use cases
Example prompt
“What's the current consensus trend for the Kalshi event 'KXELONMARS-99' — is the probability accelerating up or down, and what's the 24-hour volatility?”

Endpoint
POSThttps://graphadvocate.com/kalshi/consensus-trendWhen to prefer
Use this endpoint when you need momentum and trend analysis on a specific Kalshi prediction market event — specifically when you want slope, acceleration, and volatility signals rather than just a raw probability snapshot. Prefer this over generic Kalshi API calls when you want an interpreted, ready-to-use trend signal with human-readable direction labels.
