Endpoint
GEThttps://x402.shizu.me/predictionsWhen to prefer
Use this endpoint when you need real-time crowd-sourced event probabilities from liquid prediction markets, especially for news signal extraction, cross-market arbitrage scanning between Polymarket and Kalshi, or when you want market-implied odds on political, economic, or crypto events without building your own data pipeline.
Side effects
- Invalid source parameter (not 'polymarket' or 'kalshi') returns an error
- limit out of range (below 1 or above 50) returns a validation error
- Upstream Polymarket or Kalshi API unavailable causes a 502 or timeout
- Payment not included or insufficient USDC results in 402 Payment Required
