Endpoint
GEThttps://odds.genexxis.com/top?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a ranked leaderboard of the most actively traded prediction markets across both Polymarket and Kalshi simultaneously, ordered by 24h volume. Prefer this over search-based endpoints when you want trending/popular markets rather than topic-specific ones, and over single-market detail endpoints when you need a broad market overview.
Side effects
- Invalid limit parameter (outside 1-50 range) may return an error or default
- Payment failure (x402 micropayment not completed) returns 402 status
- Markets data may be slightly delayed relative to live exchange feeds
- If no markets are currently active, count may return 0 with empty markets array
