Technical details
Endpoint
GEThttps://odds.genexxis.com/market?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need deep detail on a single known prediction market — particularly when you already have the market id, slug, or ticker from a prior search. Prefer this over the search endpoint when you want bid/ask spreads, open interest, or granular 24h price history rather than just top-level odds across many markets.
Side effects
- Invalid or unknown market id/slug/ticker returns an error or empty response
- Wrong venue specified (e.g. passing a Kalshi ticker as polymarket) causes lookup failure
- Market may be closed or resolved, returning no active bid/ask
- Rate limit or payment failure returns a 402 error
- Stale or missing price history if the market has low activity
