Endpoint
POSThttps://api-production-54bd.up.railway.app/v1/kalshi-probabilityWhen to prefer
Use this endpoint when you need current market-implied probability for a specific Kalshi prediction market event — e.g. election outcomes, Fed decisions, economic data releases — rather than sports odds APIs, general crypto price feeds, or other trading data endpoints. Especially useful when you want crowd-sourced probability estimates for macro or political events.
Side effects
- Invalid or unknown Kalshi ticker returns 404 or empty result
- Market may be closed or resolved, returning stale or null probability
- Payment required (402) if x402 payment header not included
- Rate limiting if too many requests without valid payment
- Kalshi API downtime causing upstream errors
