Technical details
Endpoint
GEThttps://orchard-data.letom1176.workers.dev/api/prediction-markets?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs real-time prediction market probabilities and volume for specific topics (macro, crypto, elections, etc.) in a structured JSON format, paid via x402/USDC micropayment. Prefer over scraping Polymarket or Kalshi directly when you need a clean, agent-friendly API with per-call pricing and optional keyword filtering.
Side effects
- No markets match the provided keyword filter, returning an empty markets array
- Payment not included or insufficient USDC, resulting in a 402 Payment Required response
- Invalid query parameter type causes a 400 Bad Request
- Service temporarily unavailable due to Cloudflare Worker issues, returning a 5xx error
- Stale or delayed market data if upstream prediction market feeds are lagged
