Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/predictions/kalshi/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-money prediction market probabilities from a US-regulated exchange (Kalshi) for economic indicators (CPI, Fed decisions, jobs), political events, weather, crypto prices, or sports. Prefer this over Polymarket when US regulatory compliance or legitimacy of the source is important, or when events are specifically listed on Kalshi but not Polymarket.
Side effects
- No markets found for the search query — returns empty results
- Query too vague returns unrelated markets
- Kalshi API downtime causes upstream errors
- Limit parameter outside 1-30 range may be rejected or clamped
- Markets may close between search and display, making results stale
