Technical details
Endpoint
GEThttps://aizamon.com/x402/v1/book?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time prediction market order book data from both Kalshi and Polymarket in a single call, especially for comparing odds across platforms or finding the highest-volume markets on a given topic. Prefer it over scraping individual exchange UIs or using exchange-specific APIs when you want a unified cross-platform view with bid/ask and volume in one response.
Side effects
- No markets returned for obscure or misspelled topic query — returns empty arrays
- Payment failure or 402 not resolved — endpoint not accessible
- Kalshi or Polymarket data source unavailable — partial or empty result
- Malformed query parameter — may return top markets as fallback or error
- Rate limiting if too many calls made in short succession
