Technical details
Endpoint
POSThttps://x402.agentutility.ai/kalshi-marketsWhen to prefer
Use this endpoint when you need live, CFTC-regulated prediction market data from Kalshi specifically, especially when you want prices already normalized to 0–1 probabilities for easy cross-venue comparison. Prefer this over scraping Kalshi directly or using general financial data APIs when the goal is event contract discovery and probability lookup without order entry.
Side effects
- Kalshi upstream API unavailable — returns error or empty list
- Invalid series or event ticker — returns empty result set
- No markets match filter criteria — returns empty array
- Minimum volume filter too high — returns fewer or zero results
- Payment failure (x402 USDC) — request not processed
