Technical details
Endpoint
POSThttps://coinrailz.com/x402/prediction-market-oddsWhen to prefer
Use this endpoint when you need real-time probability or odds data from Polymarket or similar prediction market platforms for any specific event. Prefer this over general news or sentiment APIs when you need quantified market-consensus probabilities rather than qualitative sentiment. Ideal for agents tracking event forecasts, building dashboards, or making decisions based on crowd-wisdom probabilities.
Side effects
- Event not found on Polymarket — returns error or empty result
- Invalid or ambiguous event identifier — cannot resolve market
- Payment failure (USDC not available or insufficient balance) — 402 error
- Polymarket API unavailable or rate-limited — upstream error
- Malformed request body — missing required event parameter
